Mux's digital surface is the closest a developer-tools company comes to a typographic magazine. The discipline is quirky-editorial filtered through a developer-aware sensibility: warm light-cream canvas (a distinctive choice in a sea of white-canvas SaaS), Rotonto display (humanist-display with quirky letterforms), Aeonik body (geometric clarity), JetBrainsMono CTAs (developer-typographic stamp), sharp 0px corners (typographic-precision discipline). The Mux orange `#ff5d00` voltage is used scarcely — the wordmark period, accent moments, syntax-highlight keywords. The cream-on-cream-on-cream surface variation (canvas → cream-elevated → cream-soft) creates depth without leaving the warm-tone family. What it rejects: white SaaS canvas, Inter-everywhere typography, pill CTAs, drop-shadow elevation, marketing-jargon, anything that competes with the typographic editorial atmosphere.
- Single-color brand voltage discipline (orange vs purple), developer-tools editorial pacing
- Typographic-precision sharp corners, developer-tools editorial confidence
- Editorial-typographic magazine influences, humanist-display approach
- Editorial design tradition, warm-tone canvas as differentiator
- JetBrainsMono typeface — direct typographic alliance with the developer-tooling lineage

description: 'Mux''s site reads as a developer-tools editorial — closer to a typographic magazine than a typical SaaS marketing surface. The base canvas is **`#e2e4dd` warm light-cream** (a distinctive desaturated sage-green that distinguishes Mux from the white-canvas SaaS default), carrying display headlines in pure black `#000000` **Rotonto** — a humanist-display typeface with quirky letterforms that signals "design-aware tech company" rather than "enterprise SaaS." Body copy runs **Aeonik** (a geometric sans), and CTA labels render in **JetBrainsMono** — a developer-typographic stamp that ties the brand to the engineer audience. Sharp 0px corners on every CTA, card, and content block reinforce the typographic-precision identity. Section rhythm alternates light-cream editorial bands with rare dark zones for code-content. The signature **Mux orange `#ff5d00`** voltage appears on the wordmark, accent moments, and selected interactive states — used scarcely, the way a financial-broadsheet uses a single accent across an issue.'

---
## 1. Visual Theme & Atmosphere
Mux's website is what happens when a developer-tools company hires a typographer instead of a brand agency. The page opens onto a warm light-cream canvas (`#e2e4dd` — a desaturated sage-green that distinguishes Mux from the white-canvas SaaS default within the first second of visual contact). The headline "Video for developers" appears at 96px in **Rotonto** at weight 400 — a humanist-display typeface with quirky terminals, generous bowls, and an editorial-typographic confidence that signals "design-aware tech company" rather than "enterprise SaaS." The negative tracking (`-1.92px` at 96px) compresses the text into magazine-cover geometry.
The chromatic discipline is committed-monochrome with a single orange voltage. Pure black `#000000` for ink, warm cream `#e2e4dd` for canvas, and **Mux orange `#ff5d00`** appearing scarcely — the wordmark period (`mux.`), syntax-highlight keywords inside code samples, accent moments on selected interactive states. The orange is so committed when it appears that you remember it; it is so withheld between appearances that you anticipate it.
Typography stacks three families with different roles. **Rotonto** carries display sizes — humanist-display, weight 400, never bold, generous negative tracking on display sizes. **Aeonik** carries body — geometric sans, weight 400 default, weight 500 for emphasis, weight 700 for strong-display body in marketing copy. **JetBrainsMono** carries CTAs, eyebrows, code, and stylistic-stamp moments — the developer-typographic alliance with the JetBrains tooling lineage. Using JetBrainsMono for CTA labels is the brand's signature move: the engineer audience reads the buttons in their daily editor's font.
Sharp 0px corners on every CTA, card, band, and hero. Mux refuses softened radius. The typographic-precision identity demands hard rectangles — closer to letterpress slab than to consumer-tech rounded buttons. Text inputs are 4px (functional), pills appear only on rare avatar plates. The dominant geometry is the rectangle.
Section rhythm alternates light-cream editorial bands with rare dark zones used for code-content (live syntax-highlighted code samples in JetBrainsMono on `#000000` ground) and certain product-launch heroes. Mux refuses drop-shadow tiers — depth comes entirely from cream-tone variation (canvas `#e2e4dd` → surface `#d4d6cf` → soft `#ecebe7`), hairline 1px solid black borders, and the dark-cream contrast of code-content bands.
**Key Characteristics:**
- Warm light-cream `#e2e4dd` canvas — the brand's most distinctive choice in a SaaS landscape of white canvases
- Single chromatic voltage: Mux orange `#ff5d00` — used scarcely (wordmark period, syntax keywords, selected states)
- Three-family typography: Rotonto (display) + Aeonik (body) + JetBrainsMono (CTAs/code)
- JetBrainsMono on CTAs — developer-typographic stamp, brand signature
- Sharp 0px corners on every CTA, card, band — typographic-precision identity
- Negative letter-spacing on display (-1.92px at 96px) — magazine-cover compression
- 1px solid black hairlines as border default — no soft greys
- No drop-shadow tiers — depth via cream-tone variation + hairlines + contrast
- Three-tier cream surface ladder (canvas → cream-elevated → cream-soft)
- Dark `#000000` zones used scarcely for code-content and certain heroes
## 2. Color Palette & Roles
### Primary
- **Cream Canvas** (`#e2e4dd`): The page floor. Warm light-cream — the brand's most distinctive color choice. Distinguishes Mux from the white-canvas SaaS default.
- **Pure Black** (`#000000`): Primary ink. Display headlines, body strong, hairline borders, button-primary fill. Mux uses pure black where competitors use charcoal.
- **Mux Orange** (`#ff5d00`): The single high-voltage chromatic moment. Wordmark period, syntax-highlight keywords, accent moments, focus ring.
### Brand & Dark
- **Orange Hover** (`#e54e00`): Press state.
- **Orange Active** (`#c54100`): Deep press feedback.
- **Orange Soft** (`#ffe5d4`): Selected-state background, badge tint.
- **Cinema Black** (`#000000`): Same hex as ink — used for code-content bands, dark hero variants, button-primary fill.
- **Dark Soft** (`#1a1a1a`): Code blocks; one tier above pure black.
### Accent
- **Accent Blue** (`#0066ff`): Rare info-badge accent. Used scarcely.
- **Accent Green** (`#00b364`): Rare success accent. Used scarcely.
- No other saturated colors. Mux deliberately refuses chromatic variety.
### Interactive
- **Link** (`#000000`): Inline links inherit ink + underline.
- **Link Hover** (`#ff5d00`): Orange shift on hover for inline links.
- **Button Primary** (`#000000`): Primary CTA fill — pure black on cream.
- **Button Hover** (`#1a1a1a`): Subtle press state.
- **Disabled** (`#8a8a8a`): Faint — disabled CTAs and form fields.
### Neutral Scale
- **Ink** `#000000` — display, headlines, button-primary fill, hairline borders
- **Body** `#1a1a1a` — running paragraph text on cream canvas
- **Muted** `#5a5a5a` — captions, photo metadata
- **Faint** `#8a8a8a` — disabled, footer secondary, form placeholder
- **Border Soft** `#a0a29a` — softer divider on cream (rare; default border is solid black)
- **Surface** `#d4d6cf` — cream-elevated, one tier above canvas
- **Surface Soft** `#ecebe7` — softer cream variant
- **Surface Strong** `#c8caBF` — heavier cream panel
- **Cream Canvas** `#e2e4dd` — page floor
### Surface & Borders
- **bg** is `#e2e4dd` warm light-cream — the canonical canvas.
- **bg-paper** `#ffffff` — used only for inset cards on cream (the card-on-cream contrast IS the elevation).
- **bg-dark** `#000000` for scoped code-content bands, certain heroes.
- **surface** `#d4d6cf` — one tier above canvas in the cream family.
- **border** is `#000000` 1px solid — Mux uses solid black hairlines as default, not soft greys. The hairline IS the typographic discipline.
- **border-on-dark** `#2a2a2a` 1px on dark.
### Shadow Colors
Mux uses **no drop-shadow tiers**. Depth comes from:
- **Cream-tone variation** (`#e2e4dd` → `#d4d6cf` → `#ecebe7` → `#c8caBF`)
- **Hairlines** (1px solid black on cream, 1px `#2a2a2a` on dark)
- **Card-on-cream contrast** (white inset cards `#ffffff` against the cream canvas)
- **Dark-on-cream contrast** (code-content bands `#000000` against the cream canvas)
- **Focus ring** is the only chrome shadow: `0 0 0 2px #ff5d00`.
### Semantic
- **Success** (`#00b364`): Confirmation states.
- **Warning** (`#ff8c00`): Validation warnings.
- **Danger** (`#e6483d`): Form errors.
- **Info** (`#0066ff`): Info badges, callouts.
## 3. Typography Rules
### Font Family
- **Display**: `Rotonto` — humanist-display typeface with quirky terminals, generous bowls, and editorial-typographic confidence. Weight 400 carries display; weight 500 carries title-md component-title sizes.
- **Body**: `Aeonik` — geometric sans, more conventional than Rotonto, engineered for paragraph reading. Weight 400 default, 500 emphasis, 700 strong-display body.
- **Mono / CTA / Stamp**: `JetBrainsMono` — the developer-typographic stamp. CTA labels, eyebrows, code blocks, technical stamps. OpenType `ss01` and `ss02` enabled for the alternate-glyph stylistic sets that give JetBrainsMono its developer-IDE character.
- **Fallback chains**: `"Rotonto Fallback", Helvetica` / `"Aeonik Fallback", Helvetica` / `"JetBrainsMono Fallback", monaco, monospace`.
- **No italics** — Mux brand voice is always upright.

### Principles
- **Display weight stays at 400.** Rotonto carries enough humanist-display character at regular weight; bolding it would lose the editorial confidence.
- **Negative letter-spacing on display only.** -0.36px to -1.92px on display sizes; body stays at 0. Magazine-cover compression.
- **JetBrainsMono on CTAs is the brand signature.** Using a developer-IDE typeface for CTA labels is the typographic alliance with the engineer audience. The CTA literally renders in their daily editor's font.
- **Three-family discipline.** Rotonto + Aeonik + JetBrainsMono — display + body + stamp. No second sans, no serif accent, no decorative type beyond these three.
- **OpenType `ss01`/`ss02` on JetBrainsMono.** The alternate-glyph stylistic sets give JetBrainsMono its IDE character — distinctive `g`, `l`, `0` glyphs that are non-negotiable.
- **Sentence-case CTAs.** "Get started", "Talk to us", "Sign up". Never uppercase; the JetBrainsMono is already doing the typographic stamping work.
- **No italics.** Voice is always upright.
- **Rotonto and Aeonik are licensed.** Open-source substitutes: **Inter** at 400 for body (closest to Aeonik), **Editorial New** for display (closest to Rotonto humanist-display), **JetBrainsMono** itself (open-source).
## 4. Component Stylings
### Buttons
All buttons use **0px sharp corners** — the typographic-precision identity.
**Primary (Black on Cream)** — the singular high-voltage action:
- Background `#000000`, text `#e2e4dd` (cream — the canvas color), font `JetBrainsMono 14/500 sentence-case`
- Padding `12px 24px`, height `44px`, border-radius `0`, no border
- Transition `background-color 200ms ease`
- Hover: background `#1a1a1a` (subtle, color-only)
- Active: background drops further
- Use case: Get started, Talk to us, Sign up
**Secondary (Outline)** — alternative action paired with primary:
- Background transparent, text `#000000`, border `1px solid #000000`
- Padding `11px 23px` (1px less for border), height `44px`, radius `0`
- Same `JetBrainsMono 14/500 sentence-case` typography
- Hover: background fills to `rgba(0,0,0,0.06)` (subtle)
- Use case: secondary CTA paired with primary
**Tertiary (Text)** — inline editorial actions:
- Background transparent, text `#000000`, no border
- Same `JetBrainsMono 14/500`
- Decoration: `underline-offset: 2px` underline always-on; arrow → indicator slides in on hover
- Use case: "Read more", "Try another video", "View documentation"
**Primary on Dark** — primary CTA on dark hero band:
- Background `#e2e4dd` cream, text `#000000`
- Same dimensions and typography
- Use case: primary CTA on code-content hero / dark band
### Hero Bands
**Light Hero** — primary hero on most pages:
- Background `#e2e4dd` cream, text `#000000`
- Display headline in `Rotonto 96/400 -1.92px` pure black
- Eyebrow above in JetBrainsMono 12/500 0.6px uppercase (e.g. "VIDEO API")
- One black primary CTA + one outline secondary, side-by-side

- Background `#ffffff` pure white, text `#000000`, radius `0`, border `1px solid #000000`, padding `32px`
- Title in `display-md 36/400 -0.36px` Rotonto + body in Aeonik 16/400 + button-tertiary text below
- Hover: border-color shifts to `#ff5d00` over 200ms (color-only, no transform, no shadow)
- Use case: feature grid on homepage, product cards
**Feature Card (Cream Elevated)** — variant in cream-only sections:
- Background `#d4d6cf` cream-elevated, text `#000000`, radius `0`, border `1px solid #000000`, padding `32px`
- Same content geometry as white inset variant
**Code Card** — live syntax-highlighted code sample:

- Font `JetBrainsMono 14/400 1.6 line-height`
- Syntax highlighting: Mux orange `#ff5d00` for keywords, cream `#e2e4dd` for strings, muted grey for comments
- Use case: API code samples, embed code demonstrations
### Spec Surfaces
**Spec Cell** — engineering-spec callout:
- Transparent background
- Value in `Rotonto 64/400 -0.64px` pure black
- Label below in `eyebrow JetBrainsMono 12/500 0.6px uppercase`
- Padding `24px 0`

- Background `#000000`, text `#e2e4dd`
- Centered display headline `Rotonto 48/400 -0.96px`
- Single cream CTA centered below
- Padding `96px` vertical
### Navigation
**Top Nav** — default nav on every page:
- Background `#e2e4dd` cream (matches canvas), text `#000000`, height `64px`, border-bottom `1px solid #000000`, sticky
- Layout: Mux wordmark top-left ("mux." with orange period at the end) + horizontal menu (Products / Solutions / Docs / Pricing / Resources) center + utilities (Sign in, Get started) right
- Menu items in `Aeonik 14/500`
- Hover: subtle underline grows beneath active item over 150ms
### Footer
**Footer Light** — closing footer on every page:
- Background `#e2e4dd` cream, text `#5a5a5a`, border-top `1px solid #000000`
- 5-column link list at desktop covering Product / Developers / Company / Resources / Legal
- Padding `64px 48px`
- Mux wordmark bottom-left below link columns
## 5. Layout Principles
### Spacing System
- **Base unit:** 4px.
- **Scale:** `4 / 8 / 16 / 24 / 32 / 48 / 64 / 96 / 128`.
- **Section padding:** 96px for major bands; 128px for the homepage hero.
- **Card internal padding:** 32px for feature cards.
- **Gutters:** 24px between cards in 3-up grids; 32px in 2-up hero splits.
### Grid & Container
- Max content width: **1280px** on editorial bands.
- Editorial body: 12-column grid.
- Feature card grids: 2-up at desktop for hero splits, 3-up for benefit grids.
- Footer: 5-column at desktop.
### Whitespace Philosophy
Generous editorial-typographic pacing. The hero band runs at viewport-height (100vh) on the homepage. Body sections sit in tighter editorial layouts with 96px section padding — enough to let typography breathe, not so much that the page feels empty. The cream canvas reads warmer than white, allowing tighter content density without feeling cramped.
### Section Cadence
The homepage rhythm: light hero → editorial-band (cream) → feature-grid (white inset cards) → code-card hero (dark) → spec-band → CTA-band-dark → footer-light. Each section's role is signalled by its background color.
## 6. Shapes & Radius Scale
| Tier | Token | Value | Use |
|------|-------|-------|-----|
| None | `none` | 0 | Every CTA, card, band, hero — dominant radius |
| Tight | `xs` | 2 | Tight chips (rare) |
| Standard | `sm` | 4 | Text inputs only |
| Comfortable | `md` | 6 | Compact UI (rare) |
| Relaxed | `lg` | 8 | Mobile-only collapse cards (rare) |
| Pill | `pill` | 9999 | Avatar plates only (very rare) |
The radius vocabulary is **sharp by default**. 0px corners are the brand button shape. There is no compound-radius geometry on the site.
## 7. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| 0 (Flat) | `#e2e4dd` cream canvas, no shadow | Body bands, footer, content surfaces |
| 1 (Cream-Elevated) | `#d4d6cf` background, no shadow | Cream-elevated cards inside cream sections |
| 2 (White Inset) | `#ffffff` white background on cream canvas, 1px solid black border | Feature cards — the contrast IS the elevation |
| 3 (Dark Inset) | `#000000` background on cream canvas | Code-content cards, dark hero zones |
| 4 (Hairline) | 1px solid `#000000` borders | All card borders, dividers |
| 5 (Photographic) | — | Mux uses minimal photography; depth is typographic |
### Shadow Philosophy
Mux refuses drop-shadow tiers. The system uses **typographic depth + cream-tone variation + hairlines + dark-on-cream contrast**. White inset cards on the cream canvas are the primary card depth treatment; dark inset cards (`#000000` on cream) are the secondary. There are no soft drop shadows under cards. The single chrome shadow is the focus ring (`0 0 0 2px #ff5d00`).
### Decorative Depth
- **White inset cards on cream** — the brand's primary card depth.
- **Dark inset zones** — code-content bands `#000000` on the cream canvas.
- **Cream-tone variation** (`#e2e4dd` → `#d4d6cf` → `#ecebe7`) carries structural elevation.
- **No gradients.** The brand refuses gradient backgrounds.
## 8. Interaction & Motion
### Easing Curves
- **Standard**: `cubic-bezier(0.4, 0, 0.2, 1)` — default ease for most micro-interactions
- **Emphasized**: `cubic-bezier(0.2, 0, 0, 1)` — stronger entrance for hero text reveals
### Duration Buckets
- **Fast** (150ms): button background-color transitions, link underline-grow
- **Standard** (200ms): card border-color shift, hover state changes
- **Slow** (300ms): section entrance fades, modal entrance
- **Hero Reveal** (600ms): staggered word-fade-in on hero headline
### Per-Component Micro-States
- **Button Primary** — hover: background-color transitions to `#1a1a1a` over 150ms (subtle, almost imperceptible). No transform.
- **Button Secondary** — hover: background fills to `rgba(0,0,0,0.06)` over 150ms.
- **Button Tertiary (Text)** — hover: arrow → indicator slides in from the right over 200ms.
- **Feature Card** — hover: border-color shifts from `#000000` to `#ff5d00` over 200ms (color-only, no transform, no shadow).
- **Link** — hover: color shifts from `#000000` to `#ff5d00` over 150ms.
- **Hero Headline** — first paint: words stagger-fade-in from invisible to visible over 600ms emphasized ease, 80ms delay between words.
### Page Transitions
Page-to-page: 200ms cross-fade. No parallax — Mux is typographic, not cinematic.
### Reduced Motion Strategy
Respects `prefers-reduced-motion: reduce`. Under reduced motion:
- Hero stagger-fade collapses to single fade-in over 200ms
- All transitions become opacity-only
- Hover states remain (color shifts are not motion-coded)
## 9. Accessibility & A11y
### Contrast Pairs (WCAG)
- **Text on Cream**: `#000000` on `#e2e4dd` = 16.2:1 — AAA at all sizes
- **Body on Cream**: `#1a1a1a` on `#e2e4dd` = 13.8:1 — AAA at all sizes
- **Text on Brand**: `#000000` on `#ff5d00` = 7.2:1 — AAA
- **Text on Dark**: `#e2e4dd` on `#000000` = 16.0:1 — AAA
- **Muted on Cream**: `#5a5a5a` on `#e2e4dd` = 5.7:1 — AA Normal
- **Faint on Cream**: `#8a8a8a` on `#e2e4dd` = 3.0:1 — fails AA at body sizes; reserved for caption-uppercase 12px+ where AA Large applies, or non-essential metadata
### Focus Indicators
- **Ring color**: `#ff5d00` (Mux orange)
- **Ring style**: `2px solid` at `2px` offset from element's outer edge
- **Focus-visible only**: ring appears only on keyboard focus, not mouse-click focus
- **0px rectangles** receive a square ring (no pill-corner softening)
### ARIA Patterns
- **Combobox** (search, select dropdowns): `role="combobox"` with `aria-expanded`, `aria-controls`, `aria-activedescendant`.
- **Listbox** (dropdown options): `role="listbox"` with `aria-selected`.
- **Dialog** (modals): `role="dialog"` with `aria-modal="true"`, `aria-labelledby`, focus trap.
- **Tabs** (docs navigation, pricing-tier toggle): `role="tablist"` with `aria-selected`. Arrow-key navigation.
- **Code block**: `<pre><code>` with `aria-label="Code sample, JavaScript"` for syntax-highlighted examples.
### Keyboard Nav Order
Tab order: skip-to-content → Mux wordmark (home) → primary nav (Products, Solutions, Docs, Pricing, Resources) → utilities (Sign in, Get started) → hero CTAs → editorial body content → footer columns.
### Screen Reader Hints
- Mux wordmark: `aria-label="Mux home"`.
- Code samples: wrapped in `<pre><code>` with appropriate `aria-label` describing language.
- Decorative typographic elements use `aria-hidden="true"`.
### Reduced Motion Handling
`@media (prefers-reduced-motion: reduce)` overrides the hero stagger-fade and all scroll-triggered transitions. Documented in §8.
## 10. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | < 640px | Hero h1 96→40px; feature card grid 1-up; nav collapses to hamburger |
| Tablet | 640–1024px | Hero h1 66px; feature card grid 2-up; nav still hamburger |
| Desktop | 1024–1280px | Hero h1 96px; feature card grid 3-up; horizontal nav appears |
| Wide | > 1280px | Editorial body content caps at 1280px |
### Touch Targets
- Primary CTA at 44px height — meets WCAG 44 × 44.
- Nav items render with 20px vertical padding for an effective 48px tap area.
### Collapsing Strategy
- **Top nav** switches to hamburger below 1024px.
- **Feature card grid**: 3-up → 2-up → 1-up.
- **Footer**: 5-column at desktop, accordion-collapsed at mobile.
- **Hero text**: maintains aspect ratio with proportional size reduction.
### Image Behavior
- Mux uses minimal photography. Any imagery (case-study screenshots, customer logos) uses AVIF + WebP fallback + JPEG floor with `loading="lazy"` except above-the-fold.
### Container Queries
Used selectively on docs-sidebar layouts where the sidebar reflows based on container width.
## 11. Content & Voice
### Tone
**Developer-confident, typographic, slightly playful.** The voice reads like a senior engineer who genuinely enjoys their craft — direct, technical, occasionally witty. There is no marketing-jargon, no "innovative" or "revolutionary." Mux talks about specific technical concerns: latency, encoding profiles, real-world video delivery edge cases. The tone respects the reader's technical literacy.
### Microcopy Patterns
- **Buttons**: action-verb + noun, sentence-case in JetBrainsMono. "Get started", "Talk to us", "Sign up", "Read the docs", "Try another video". Never uppercase, never "Click here."
- **Eyebrows**: uppercase context cue in JetBrainsMono. "VIDEO API", "MUX DATA", "LIVE STREAMING".
- **Error message recipe**: `[What went wrong]. [What to do.]` — direct and technical. "Couldn't fetch playback ID. Check your environment variables and try again."
- **Success confirmations**: terse and dry. "Asset created." "Stream is live." No exclamation marks — Mux is too dry for them.
- **Form labels**: lowercase technical-style labels above pill inputs in some contexts; capitalized noun phrases in others. Both work; the brand voice is direct.
### Empty States
- **No assets**: "No assets yet. Create your first one to get started."
- **API errors**: "Mux API returned an error. Check your auth token and try again."
- **Empty search**: "No results — try a different query."
### CTA Verb Conventions
- **Get started** — primary verb on signup CTAs (sentence-case)
- **Talk to us** — for sales/contact (Mux uses "Talk to us" rather than "Contact sales" — friendlier)
- **Read the docs** — for documentation (not "View docs" — Mux uses "Read")
- **Try another video** — interactive demos (the "another" implies the demo is already running)
- **Sign in** — for returning users (never "Login")
## 12. Dark Mode & Theming
Mux has **no global user-facing dark/light toggle**. The site is light-cream-by-default. Dark sections are scoped contextual surfaces — code-content bands at `#000000`, code blocks, certain hero variants for product launches. The token swap is local and predictable:
- `bg`: `#e2e4dd` → `#000000`
- `text`: `#000000` → `#e2e4dd`
- `text-body`: `#1a1a1a` → `#e2e4dd`
- `border`: `#000000` → `#e2e4dd`
- `surface`: `#d4d6cf` → `#1a1a1a`
- `brand` and `on-brand` stay unchanged: orange voltage renders identically on both grounds.
When dark zones appear, they're scoped — code samples, code-content product launches, certain CTA bands. The site never inverts globally.
## 13. Lineage & Influences
Mux's digital surface is the closest a developer-tools company comes to a typographic magazine. The discipline is quirky-editorial filtered through a developer-aware sensibility: warm light-cream canvas, Rotonto humanist-display, Aeonik geometric body, JetBrainsMono CTAs, sharp 0px corners. The cream canvas is the boldest brand choice — a distinctive choice in a sea of white-canvas SaaS that distinguishes Mux from competitors within the first second of visual contact.
Influences run from Stripe's single-color brand voltage discipline to Linear's typographic-precision sharp corners, with editorial roots in the It's Nice That / Pentagram / Werner Design Werks tradition. The JetBrainsMono CTA usage is a direct typographic alliance with the JetBrains tooling lineage — engineers reading their own daily editor's font on the marketing buttons.
What it rejects: white SaaS canvas, Inter-everywhere typography, pill CTAs, drop-shadow elevation, marketing-jargon, anything that competes with the typographic editorial atmosphere.
**Named influences:**
- Stripe — single-color brand voltage discipline (https://stripe.com)
- Linear — typographic-precision sharp corners, developer-tools editorial confidence (https://linear.app)
- It's Nice That / The Type Directors Club — editorial-typographic magazine influences (https://www.itsnicethat.com)
- Werner Design Werks / Pentagram — editorial design tradition (https://www.pentagram.com)
- JetBrains — JetBrainsMono typeface, direct typographic alliance (https://www.jetbrains.com/lp/mono/)
## 14. Do's and Don'ts
### Do
- Use warm light-cream `#e2e4dd` as the canvas — the brand's most distinctive choice. Refuse white SaaS canvas.
- Reserve Mux orange `#ff5d00` for the wordmark period, syntax-highlight keywords, accent moments, focus ring — used scarcely.
- Use JetBrainsMono on every CTA label — the developer-typographic stamp is the brand signature.
- Use Rotonto for display sizes at weight 400 with negative tracking — humanist-display character.
- Use Aeonik for body at 16/400 normal tracking.
- Set every CTA at 0px sharp corners — the typographic-precision identity.
- Use 1px solid black hairlines as the default border — never soft greys.
- Place white inset cards on cream canvas as the primary card treatment — the contrast IS the elevation.
- Render the Mux wordmark with the orange period after "mux." — non-negotiable.
- Use sentence-case CTAs ("Get started", "Talk to us").
### Don't
- Don't use white as the primary canvas. Cream `#e2e4dd` is the brand voice.
- Don't introduce a saturated brand color other than Mux orange.
- Don't bold display copy. Rotonto at 400 is the editorial-humanist confidence.
- Don't use pill CTAs. Sharp 0px corners are the brand button.
- Don't use drop-shadow tiers. Depth comes from cream-tone variation + hairlines + contrast.
- Don't use uppercase CTA labels. JetBrainsMono is doing the typographic-stamp work; uppercase would over-stamp.
- Don't use Inter or system-ui for body. Aeonik is the brand sans.
- Don't use ornamental gradients. The site is cream + black + orange.
- Don't translate "Talk to us" to "Contact Sales" — too transactional.
- Don't use exclamation marks in microcopy. Mux is dry.
- Don't add italic display copy. Rotonto is always upright.
- Don't use soft-grey hairlines `#e0e0e0`-style. Mux uses solid black hairlines as the default.

### Example Component Prompts
- "Create a Mux hero band on warm light-cream `#e2e4dd` canvas, 100vh tall. Above the headline, an uppercase JetBrainsMono eyebrow 'VIDEO API' in 12/500 with 0.6px tracking. The headline 'Video for developers' renders in Rotonto 96px weight 400 with -1.92px letter-spacing in pure black `#000000`. Words stagger-fade-in over 600ms on first paint. Below the headline, two side-by-side CTAs: a black `#000000` 'Get started' button (JetBrainsMono 14/500 sentence-case, 12×24 padding, 44px tall, 0px corners, cream `#e2e4dd` text) and a transparent outline 'Talk to us' button (1px solid black border, black text, same dimensions)."
- "Design a Mux feature card: white `#ffffff` paper background inset on the cream `#e2e4dd` canvas, 0px sharp corners, 1px solid `#000000` border, 32px padding. Title in Rotonto 36px weight 400 with -0.36px tracking pure black, 16px gap, body copy in Aeonik 16/400 black, 24px gap, and a 'Read more →' tertiary text button in JetBrainsMono 14/500 with always-on underline-offset 2px. Hover: border-color shifts from black to Mux orange `#ff5d00` over 200ms — color-only, no transform, no shadow."
- "Build a Mux code card: pure black `#000000` background, 0px sharp corners, 32px padding. Code rendered in JetBrainsMono 14/400 with 1.6 line-height. Syntax highlighting: keywords (`const`, `function`, `return`) in Mux orange `#ff5d00`, strings in cream `#e2e4dd`, comments in muted grey `#5a5a5a`. Display a working API code sample (Mux Asset creation in JavaScript)."

- "Build a Mux top nav: 64px tall on `#e2e4dd` cream (matches canvas), 1px solid `#000000` border-bottom, sticky. Wordmark top-left rendered as 'mux.' in Aeonik 18/700 black with the period in Mux orange `#ff5d00` (the period is the only orange element in the wordmark). Horizontal menu (Products / Solutions / Docs / Pricing / Resources) center in Aeonik 14/500 black. Right side: 'Sign in' (text button) and 'Get started' (black primary CTA, 44px tall, 0px corners)."
- "Design a Mux pre-footer CTA band: pure black `#000000` background, centered display headline 'Build with Mux.' in Rotonto 48/400 -0.96px cream `#e2e4dd`, 96px vertical padding. Single cream-on-dark CTA centered below: cream `#e2e4dd` background, black text in JetBrainsMono 14/500 ('Get started'), 12×24 padding, 44px tall, 0px corners."
### Iteration Guide
1. Focus on ONE component at a time. Reference its YAML key (`button-primary`, `feature-card`, `code-card`).
2. Variants live as separate entries inside `components:`.
3. CTAs default to 0px sharp corners — typographic-precision identity. Never pill, never softened.
4. Use color tokens (`brand`, `text`, `surface`) — never inline hex on multiple components.
5. Hover states change color only — feature cards shift border-color from black to Mux orange.
6. Three-family typography discipline: Rotonto (display) + Aeonik (body) + JetBrainsMono (CTAs/code/eyebrows). Never substitute.
7. Mux orange stays scarce — wordmark period, syntax keywords, focus ring, hover-border-shift only.
8. Use the explicit spacing ladder (4 / 8 / 16 / 24 / 32 / 48 / 64 / 96 / 128). Section padding 96px; hero 128px.
9. Cream canvas + white inset cards is the primary card pattern — the contrast IS the elevation.
10. Solid black hairlines (1px solid #000000) are the default border — never soft greys.
1. Visual Theme & Atmosphere
Mux’s website is what happens when a developer-tools company hires a typographer instead of a brand agency. The page opens onto a warm light-cream canvas (#e2e4dd — a desaturated sage-green that distinguishes Mux from the white-canvas SaaS default within the first second of visual contact). The headline “Video for developers” appears at 96px in Rotonto at weight 400 — a humanist-display typeface with quirky terminals, generous bowls, and an editorial-typographic confidence that signals “design-aware tech company” rather than “enterprise SaaS.” The negative tracking (-1.92px at 96px) compresses the text into magazine-cover geometry.
The chromatic discipline is committed-monochrome with a single orange voltage. Pure black #000000 for ink, warm cream #e2e4dd for canvas, and Mux orange #ff5d00 appearing scarcely — the wordmark period (mux.), syntax-highlight keywords inside code samples, accent moments on selected interactive states. The orange is so committed when it appears that you remember it; it is so withheld between appearances that you anticipate it.
Typography stacks three families with different roles. Rotonto carries display sizes — humanist-display, weight 400, never bold, generous negative tracking on display sizes. Aeonik carries body — geometric sans, weight 400 default, weight 500 for emphasis, weight 700 for strong-display body in marketing copy. JetBrainsMono carries CTAs, eyebrows, code, and stylistic-stamp moments — the developer-typographic alliance with the JetBrains tooling lineage. Using JetBrainsMono for CTA labels is the brand’s signature move: the engineer audience reads the buttons in their daily editor’s font.
Sharp 0px corners on every CTA, card, band, and hero. Mux refuses softened radius. The typographic-precision identity demands hard rectangles — closer to letterpress slab than to consumer-tech rounded buttons. Text inputs are 4px (functional), pills appear only on rare avatar plates. The dominant geometry is the rectangle.
Section rhythm alternates light-cream editorial bands with rare dark zones used for code-content (live syntax-highlighted code samples in JetBrainsMono on #000000 ground) and certain product-launch heroes. Mux refuses drop-shadow tiers — depth comes entirely from cream-tone variation (canvas #e2e4dd → surface #d4d6cf → soft #ecebe7), hairline 1px solid black borders, and the dark-cream contrast of code-content bands.
Key Characteristics:
- Warm light-cream
#e2e4ddcanvas — the brand’s most distinctive choice in a SaaS landscape of white canvases - Single chromatic voltage: Mux orange
#ff5d00— used scarcely (wordmark period, syntax keywords, selected states) - Three-family typography: Rotonto (display) + Aeonik (body) + JetBrainsMono (CTAs/code)
- JetBrainsMono on CTAs — developer-typographic stamp, brand signature
- Sharp 0px corners on every CTA, card, band — typographic-precision identity
- Negative letter-spacing on display (-1.92px at 96px) — magazine-cover compression
- 1px solid black hairlines as border default — no soft greys
- No drop-shadow tiers — depth via cream-tone variation + hairlines + contrast
- Three-tier cream surface ladder (canvas → cream-elevated → cream-soft)
- Dark
#000000zones used scarcely for code-content and certain heroes
2. Color Palette & Roles
Primary
- Cream Canvas (
#e2e4dd): The page floor. Warm light-cream — the brand’s most distinctive color choice. Distinguishes Mux from the white-canvas SaaS default. - Pure Black (
#000000): Primary ink. Display headlines, body strong, hairline borders, button-primary fill. Mux uses pure black where competitors use charcoal. - Mux Orange (
#ff5d00): The single high-voltage chromatic moment. Wordmark period, syntax-highlight keywords, accent moments, focus ring.
Brand & Dark
- Orange Hover (
#e54e00): Press state. - Orange Active (
#c54100): Deep press feedback. - Orange Soft (
#ffe5d4): Selected-state background, badge tint. - Cinema Black (
#000000): Same hex as ink — used for code-content bands, dark hero variants, button-primary fill. - Dark Soft (
#1a1a1a): Code blocks; one tier above pure black.
Accent
- Accent Blue (
#0066ff): Rare info-badge accent. Used scarcely. - Accent Green (
#00b364): Rare success accent. Used scarcely. - No other saturated colors. Mux deliberately refuses chromatic variety.
Interactive
- Link (
#000000): Inline links inherit ink + underline. - Link Hover (
#ff5d00): Orange shift on hover for inline links. - Button Primary (
#000000): Primary CTA fill — pure black on cream. - Button Hover (
#1a1a1a): Subtle press state. - Disabled (
#8a8a8a): Faint — disabled CTAs and form fields.
Neutral Scale
- Ink
#000000— display, headlines, button-primary fill, hairline borders - Body
#1a1a1a— running paragraph text on cream canvas - Muted
#5a5a5a— captions, photo metadata - Faint
#8a8a8a— disabled, footer secondary, form placeholder - Border Soft
#a0a29a— softer divider on cream (rare; default border is solid black) - Surface
#d4d6cf— cream-elevated, one tier above canvas - Surface Soft
#ecebe7— softer cream variant - Surface Strong
#c8caBF— heavier cream panel - Cream Canvas
#e2e4dd— page floor
Surface & Borders
- bg is
#e2e4ddwarm light-cream — the canonical canvas. - bg-paper
#ffffff— used only for inset cards on cream (the card-on-cream contrast IS the elevation). - bg-dark
#000000for scoped code-content bands, certain heroes. - surface
#d4d6cf— one tier above canvas in the cream family. - border is
#0000001px solid — Mux uses solid black hairlines as default, not soft greys. The hairline IS the typographic discipline. - border-on-dark
#2a2a2a1px on dark.
Shadow Colors
Mux uses no drop-shadow tiers. Depth comes from:
- Cream-tone variation (
#e2e4dd→#d4d6cf→#ecebe7→#c8caBF) - Hairlines (1px solid black on cream, 1px
#2a2a2aon dark) - Card-on-cream contrast (white inset cards
#ffffffagainst the cream canvas) - Dark-on-cream contrast (code-content bands
#000000against the cream canvas) - Focus ring is the only chrome shadow:
0 0 0 2px #ff5d00.
Semantic
- Success (
#00b364): Confirmation states. - Warning (
#ff8c00): Validation warnings. - Danger (
#e6483d): Form errors. - Info (
#0066ff): Info badges, callouts.
3. Typography Rules
Font Family
- Display:
Rotonto— humanist-display typeface with quirky terminals, generous bowls, and editorial-typographic confidence. Weight 400 carries display; weight 500 carries title-md component-title sizes. - Body:
Aeonik— geometric sans, more conventional than Rotonto, engineered for paragraph reading. Weight 400 default, 500 emphasis, 700 strong-display body. - Mono / CTA / Stamp:
JetBrainsMono— the developer-typographic stamp. CTA labels, eyebrows, code blocks, technical stamps. OpenTypess01andss02enabled for the alternate-glyph stylistic sets that give JetBrainsMono its developer-IDE character. - Fallback chains:
"Rotonto Fallback", Helvetica/"Aeonik Fallback", Helvetica/"JetBrainsMono Fallback", monaco, monospace. - No italics — Mux brand voice is always upright.

Principles
- Display weight stays at 400. Rotonto carries enough humanist-display character at regular weight; bolding it would lose the editorial confidence.
- Negative letter-spacing on display only. -0.36px to -1.92px on display sizes; body stays at 0. Magazine-cover compression.
- JetBrainsMono on CTAs is the brand signature. Using a developer-IDE typeface for CTA labels is the typographic alliance with the engineer audience. The CTA literally renders in their daily editor’s font.
- Three-family discipline. Rotonto + Aeonik + JetBrainsMono — display + body + stamp. No second sans, no serif accent, no decorative type beyond these three.
- OpenType
ss01/ss02on JetBrainsMono. The alternate-glyph stylistic sets give JetBrainsMono its IDE character — distinctiveg,l,0glyphs that are non-negotiable. - Sentence-case CTAs. “Get started”, “Talk to us”, “Sign up”. Never uppercase; the JetBrainsMono is already doing the typographic stamping work.
- No italics. Voice is always upright.
- Rotonto and Aeonik are licensed. Open-source substitutes: Inter at 400 for body (closest to Aeonik), Editorial New for display (closest to Rotonto humanist-display), JetBrainsMono itself (open-source).

5. Layout Principles
Spacing System
- Base unit: 4px.
- Scale:
4 / 8 / 16 / 24 / 32 / 48 / 64 / 96 / 128. - Section padding: 96px for major bands; 128px for the homepage hero.
- Card internal padding: 32px for feature cards.
- Gutters: 24px between cards in 3-up grids; 32px in 2-up hero splits.
Grid & Container
- Max content width: 1280px on editorial bands.
- Editorial body: 12-column grid.
- Feature card grids: 2-up at desktop for hero splits, 3-up for benefit grids.
- Footer: 5-column at desktop.
Whitespace Philosophy
Generous editorial-typographic pacing. The hero band runs at viewport-height (100vh) on the homepage. Body sections sit in tighter editorial layouts with 96px section padding — enough to let typography breathe, not so much that the page feels empty. The cream canvas reads warmer than white, allowing tighter content density without feeling cramped.
Section Cadence
The homepage rhythm: light hero → editorial-band (cream) → feature-grid (white inset cards) → code-card hero (dark) → spec-band → CTA-band-dark → footer-light. Each section’s role is signalled by its background color.
6. Shapes & Radius Scale
| Tier | Token | Value | Use |
|---|---|---|---|
| None | none | 0 | Every CTA, card, band, hero — dominant radius |
| Tight | xs | 2 | Tight chips (rare) |
| Standard | sm | 4 | Text inputs only |
| Comfortable | md | 6 | Compact UI (rare) |
| Relaxed | lg | 8 | Mobile-only collapse cards (rare) |
| Pill | pill | 9999 | Avatar plates only (very rare) |
The radius vocabulary is sharp by default. 0px corners are the brand button shape. There is no compound-radius geometry on the site.
7. Depth & Elevation
| Level | Treatment | Use |
|---|---|---|
| 0 (Flat) | #e2e4dd cream canvas, no shadow | Body bands, footer, content surfaces |
| 1 (Cream-Elevated) | #d4d6cf background, no shadow | Cream-elevated cards inside cream sections |
| 2 (White Inset) | #ffffff white background on cream canvas, 1px solid black border | Feature cards — the contrast IS the elevation |
| 3 (Dark Inset) | #000000 background on cream canvas | Code-content cards, dark hero zones |
| 4 (Hairline) | 1px solid #000000 borders | All card borders, dividers |
| 5 (Photographic) | — | Mux uses minimal photography; depth is typographic |
Shadow Philosophy
Mux refuses drop-shadow tiers. The system uses typographic depth + cream-tone variation + hairlines + dark-on-cream contrast. White inset cards on the cream canvas are the primary card depth treatment; dark inset cards (#000000 on cream) are the secondary. There are no soft drop shadows under cards. The single chrome shadow is the focus ring (0 0 0 2px #ff5d00).
Decorative Depth
- White inset cards on cream — the brand’s primary card depth.
- Dark inset zones — code-content bands
#000000on the cream canvas. - Cream-tone variation (
#e2e4dd→#d4d6cf→#ecebe7) carries structural elevation. - No gradients. The brand refuses gradient backgrounds.
8. Interaction & Motion
Easing Curves
- Standard:
cubic-bezier(0.4, 0, 0.2, 1)— default ease for most micro-interactions - Emphasized:
cubic-bezier(0.2, 0, 0, 1)— stronger entrance for hero text reveals
Duration Buckets
- Fast (150ms): button background-color transitions, link underline-grow
- Standard (200ms): card border-color shift, hover state changes
- Slow (300ms): section entrance fades, modal entrance
- Hero Reveal (600ms): staggered word-fade-in on hero headline
Per-Component Micro-States
- Button Primary — hover: background-color transitions to
#1a1a1aover 150ms (subtle, almost imperceptible). No transform. - Button Secondary — hover: background fills to
rgba(0,0,0,0.06)over 150ms. - Button Tertiary (Text) — hover: arrow → indicator slides in from the right over 200ms.
- Feature Card — hover: border-color shifts from
#000000to#ff5d00over 200ms (color-only, no transform, no shadow). - Link — hover: color shifts from
#000000to#ff5d00over 150ms. - Hero Headline — first paint: words stagger-fade-in from invisible to visible over 600ms emphasized ease, 80ms delay between words.
Page Transitions
Page-to-page: 200ms cross-fade. No parallax — Mux is typographic, not cinematic.
Reduced Motion Strategy
Respects prefers-reduced-motion: reduce. Under reduced motion:
- Hero stagger-fade collapses to single fade-in over 200ms
- All transitions become opacity-only
- Hover states remain (color shifts are not motion-coded)
9. Accessibility & A11y
Contrast Pairs (WCAG)
- Text on Cream:
#000000on#e2e4dd= 16.2:1 — AAA at all sizes - Body on Cream:
#1a1a1aon#e2e4dd= 13.8:1 — AAA at all sizes - Text on Brand:
#000000on#ff5d00= 7.2:1 — AAA - Text on Dark:
#e2e4ddon#000000= 16.0:1 — AAA - Muted on Cream:
#5a5a5aon#e2e4dd= 5.7:1 — AA Normal - Faint on Cream:
#8a8a8aon#e2e4dd= 3.0:1 — fails AA at body sizes; reserved for caption-uppercase 12px+ where AA Large applies, or non-essential metadata
Focus Indicators
- Ring color:
#ff5d00(Mux orange) - Ring style:
2px solidat2pxoffset from element’s outer edge - Focus-visible only: ring appears only on keyboard focus, not mouse-click focus
- 0px rectangles receive a square ring (no pill-corner softening)
ARIA Patterns
- Combobox (search, select dropdowns):
role="combobox"witharia-expanded,aria-controls,aria-activedescendant. - Listbox (dropdown options):
role="listbox"witharia-selected. - Dialog (modals):
role="dialog"witharia-modal="true",aria-labelledby, focus trap. - Tabs (docs navigation, pricing-tier toggle):
role="tablist"witharia-selected. Arrow-key navigation. - Code block:
<pre><code>witharia-label="Code sample, JavaScript"for syntax-highlighted examples.
Keyboard Nav Order
Tab order: skip-to-content → Mux wordmark (home) → primary nav (Products, Solutions, Docs, Pricing, Resources) → utilities (Sign in, Get started) → hero CTAs → editorial body content → footer columns.
Screen Reader Hints
- Mux wordmark:
aria-label="Mux home". - Code samples: wrapped in
<pre><code>with appropriatearia-labeldescribing language. - Decorative typographic elements use
aria-hidden="true".
Reduced Motion Handling
@media (prefers-reduced-motion: reduce) overrides the hero stagger-fade and all scroll-triggered transitions. Documented in §8.
10. Responsive Behavior
Breakpoints
| Name | Width | Key Changes |
|---|---|---|
| Mobile | < 640px | Hero h1 96→40px; feature card grid 1-up; nav collapses to hamburger |
| Tablet | 640–1024px | Hero h1 66px; feature card grid 2-up; nav still hamburger |
| Desktop | 1024–1280px | Hero h1 96px; feature card grid 3-up; horizontal nav appears |
| Wide | > 1280px | Editorial body content caps at 1280px |
Touch Targets
- Primary CTA at 44px height — meets WCAG 44 × 44.
- Nav items render with 20px vertical padding for an effective 48px tap area.
Collapsing Strategy
- Top nav switches to hamburger below 1024px.
- Feature card grid: 3-up → 2-up → 1-up.
- Footer: 5-column at desktop, accordion-collapsed at mobile.
- Hero text: maintains aspect ratio with proportional size reduction.
Image Behavior
- Mux uses minimal photography. Any imagery (case-study screenshots, customer logos) uses AVIF + WebP fallback + JPEG floor with
loading="lazy"except above-the-fold.
Container Queries
Used selectively on docs-sidebar layouts where the sidebar reflows based on container width.
11. Content & Voice
Tone
Developer-confident, typographic, slightly playful. The voice reads like a senior engineer who genuinely enjoys their craft — direct, technical, occasionally witty. There is no marketing-jargon, no “innovative” or “revolutionary.” Mux talks about specific technical concerns: latency, encoding profiles, real-world video delivery edge cases. The tone respects the reader’s technical literacy.
Microcopy Patterns
- Buttons: action-verb + noun, sentence-case in JetBrainsMono. “Get started”, “Talk to us”, “Sign up”, “Read the docs”, “Try another video”. Never uppercase, never “Click here.”
- Eyebrows: uppercase context cue in JetBrainsMono. “VIDEO API”, “MUX DATA”, “LIVE STREAMING”.
- Error message recipe:
[What went wrong]. [What to do.]— direct and technical. “Couldn’t fetch playback ID. Check your environment variables and try again.” - Success confirmations: terse and dry. “Asset created.” “Stream is live.” No exclamation marks — Mux is too dry for them.
- Form labels: lowercase technical-style labels above pill inputs in some contexts; capitalized noun phrases in others. Both work; the brand voice is direct.
Empty States
- No assets: “No assets yet. Create your first one to get started.”
- API errors: “Mux API returned an error. Check your auth token and try again.”
- Empty search: “No results — try a different query.”
CTA Verb Conventions
- Get started — primary verb on signup CTAs (sentence-case)
- Talk to us — for sales/contact (Mux uses “Talk to us” rather than “Contact sales” — friendlier)
- Read the docs — for documentation (not “View docs” — Mux uses “Read”)
- Try another video — interactive demos (the “another” implies the demo is already running)
- Sign in — for returning users (never “Login”)
12. Dark Mode & Theming
Mux has no global user-facing dark/light toggle. The site is light-cream-by-default. Dark sections are scoped contextual surfaces — code-content bands at #000000, code blocks, certain hero variants for product launches. The token swap is local and predictable:
bg:#e2e4dd→#000000text:#000000→#e2e4ddtext-body:#1a1a1a→#e2e4ddborder:#000000→#e2e4ddsurface:#d4d6cf→#1a1a1abrandandon-brandstay unchanged: orange voltage renders identically on both grounds.
When dark zones appear, they’re scoped — code samples, code-content product launches, certain CTA bands. The site never inverts globally.
13. Lineage & Influences
Mux’s digital surface is the closest a developer-tools company comes to a typographic magazine. The discipline is quirky-editorial filtered through a developer-aware sensibility: warm light-cream canvas, Rotonto humanist-display, Aeonik geometric body, JetBrainsMono CTAs, sharp 0px corners. The cream canvas is the boldest brand choice — a distinctive choice in a sea of white-canvas SaaS that distinguishes Mux from competitors within the first second of visual contact.
Influences run from Stripe’s single-color brand voltage discipline to Linear’s typographic-precision sharp corners, with editorial roots in the It’s Nice That / Pentagram / Werner Design Werks tradition. The JetBrainsMono CTA usage is a direct typographic alliance with the JetBrains tooling lineage — engineers reading their own daily editor’s font on the marketing buttons.
What it rejects: white SaaS canvas, Inter-everywhere typography, pill CTAs, drop-shadow elevation, marketing-jargon, anything that competes with the typographic editorial atmosphere.
Named influences:
- Stripe — single-color brand voltage discipline (https://stripe.com)
- Linear — typographic-precision sharp corners, developer-tools editorial confidence (https://linear.app)
- It’s Nice That / The Type Directors Club — editorial-typographic magazine influences (https://www.itsnicethat.com)
- Werner Design Werks / Pentagram — editorial design tradition (https://www.pentagram.com)
- JetBrains — JetBrainsMono typeface, direct typographic alliance (https://www.jetbrains.com/lp/mono/)
14. Do’s and Don’ts
Do
- Use warm light-cream
#e2e4ddas the canvas — the brand’s most distinctive choice. Refuse white SaaS canvas. - Reserve Mux orange
#ff5d00for the wordmark period, syntax-highlight keywords, accent moments, focus ring — used scarcely. - Use JetBrainsMono on every CTA label — the developer-typographic stamp is the brand signature.
- Use Rotonto for display sizes at weight 400 with negative tracking — humanist-display character.
- Use Aeonik for body at 16/400 normal tracking.
- Set every CTA at 0px sharp corners — the typographic-precision identity.
- Use 1px solid black hairlines as the default border — never soft greys.
- Place white inset cards on cream canvas as the primary card treatment — the contrast IS the elevation.
- Render the Mux wordmark with the orange period after “mux.” — non-negotiable.
- Use sentence-case CTAs (“Get started”, “Talk to us”).
Don’t
- Don’t use white as the primary canvas. Cream
#e2e4ddis the brand voice. - Don’t introduce a saturated brand color other than Mux orange.
- Don’t bold display copy. Rotonto at 400 is the editorial-humanist confidence.
- Don’t use pill CTAs. Sharp 0px corners are the brand button.
- Don’t use drop-shadow tiers. Depth comes from cream-tone variation + hairlines + contrast.
- Don’t use uppercase CTA labels. JetBrainsMono is doing the typographic-stamp work; uppercase would over-stamp.
- Don’t use Inter or system-ui for body. Aeonik is the brand sans.
- Don’t use ornamental gradients. The site is cream + black + orange.
- Don’t translate “Talk to us” to “Contact Sales” — too transactional.
- Don’t use exclamation marks in microcopy. Mux is dry.
- Don’t add italic display copy. Rotonto is always upright.
- Don’t use soft-grey hairlines
#e0e0e0-style. Mux uses solid black hairlines as the default.

Iteration Guide
- Focus on ONE component at a time. Reference its YAML key (
button-primary,feature-card,code-card). - Variants live as separate entries inside
components:. - CTAs default to 0px sharp corners — typographic-precision identity. Never pill, never softened.
- Use color tokens (
brand,text,surface) — never inline hex on multiple components. - Hover states change color only — feature cards shift border-color from black to Mux orange.
- Three-family typography discipline: Rotonto (display) + Aeonik (body) + JetBrainsMono (CTAs/code/eyebrows). Never substitute.
- Mux orange stays scarce — wordmark period, syntax keywords, focus ring, hover-border-shift only.
- Use the explicit spacing ladder (4 / 8 / 16 / 24 / 32 / 48 / 64 / 96 / 128). Section padding 96px; hero 128px.
- Cream canvas + white inset cards is the primary card pattern — the contrast IS the elevation.
- Solid black hairlines (1px solid #000000) are the default border — never soft greys.
