PropelAuth's marketing site is the canonical B2B-multi-tenant auth canvas — a white ground anchored on body slate (`#343a40`) with hero display in SF Pro Rounded at 60/900 (Heavy weight). The two-colour brand system — deep-navy (`#151531`) for gravitas paired with indigo-violet (`#5d5cf5`) for emphasis — is the move that distinguishes PropelAuth from single-brand-colour peers. Display in SF Pro Rounded is the typographic signature: Heavy weight at large display sizes gives the page an Apple-product-marketing softness that is unique in the auth space, while body Inter handles the modern dev-tool foundation. The role-badge system (Admin red, Member green, Viewer violet) extends the chromatic discipline into the multi-tenant feature surface area. The signature illustration is the live organization dashboard preview — showing PropelAuth's actual multi-tenant UI with org switcher, role hierarchies, invitations, SSO, and audit logs.
- SF Pro Rounded at Heavy weight (900) is Apple's signature display move post-2017.
- Confidence-via-restraint chromatic discipline and hairline-bordered cards.
- Predecessor in identity-platform aesthetic — PropelAuth differentiates with B2B-multi-tenant focus.
- Frosted-glass navbar, restraint discipline, modern dev-tool foundation.
- B2B-enterprise-ready positioning — PropelAuth differentiates with the multi-tenant + role-badge focus.

description: 'PropelAuth''s marketing site is the canonical B2B-multi-tenant auth canvas — a white ground (`#ffffff`) anchored on body slate (`#343a40`) with hero display in **SF Pro Rounded** at 60/900 carrying near-zero tracking. The brand colour is **deep-navy `#151531`** for headings — a confident dark indigo that carries the B2B-platform gravitas without reaching for corporate-blue cliché. Display flips into white on darker bands where deep-blue cards (`#252550`) anchor the brand-emphasized "Organizations, Roles, RBAC" feature blocks. The SF Pro Rounded display weight at 900 (Heavy) is the most distinctive type move — it gives the page an Apple-product-marketing softness that distinguishes PropelAuth from Inter-default peers like WorkOS, Clerk, and Stytch. Body runs in **Inter** at 16/400. Where competitors plant their flag on auth-as-utility, PropelAuth''s positioning is explicitly "B2B multi-tenant from day one" — the entire page architecture (organizations dashboards, role hierarchies, SAML SSO, audit logs) is designed for B2B SaaS founders building multi-tenant products. The result is the only auth platform that successfully combines Apple-marketing-polished display typography with B2B-multi-tenant-platform feature density.'

## 1. Visual Theme & Atmosphere
PropelAuth's marketing site is the canonical **B2B-multi-tenant auth canvas** — a white ground (`#ffffff`) anchored on body slate (`#343a40`) with hero display in **SF Pro Rounded** at 60/900 — a Heavy weight that immediately signals "Apple-marketing polished" while the underlying brand colour deep-navy (`#151531`) signals "B2B-platform serious". This combination — Apple-rounded display + deep-navy ink — is the most distinctive type-and-colour pairing in the auth space. The page reads as a B2B-multi-tenant platform built by founders who care about polish: confident, considered, slightly playful in the type, completely rigorous in the feature set.
The chromatic system is **white + deep-navy + indigo-violet**. The canvas is pure `#ffffff`. Body text runs in `#343a40` (slate, slightly warmer than gray). Display headlines and the primary CTA fill use **`#151531` deep-navy** — a confident dark indigo that has slight purple undertones, reading as enterprise without enterprise-blue cliché. The accent colour is **`#5d5cf5` indigo-violet** — used for the brand mark, focus rings, eyebrow pills, role-viewer badges, and brand-emphasized "Try free" CTAs. Where most B2B-identity sites use a single brand colour, PropelAuth maintains a **two-colour brand system**: deep-navy carries the gravitas, violet carries the brand emphasis. The two work as a duet rather than competing.
Type runs **SF Pro Rounded** for display and **Inter** for body. SF Pro Rounded is Apple's rounded variant of SF Pro Display — used here at weight 900 (Heavy) for hero copy and h1, weight 700 for h3/h4, and 600 for h5. The 900 weight is the typographic signature: it's heavier than any conventional B2B-identity display weight (most run 500–700), and it gives the page a distinctly Apple-marketing-polished feel that distinguishes PropelAuth from Inter-default peers like WorkOS, Clerk, and Stytch. Body type is Inter at 16/400. Code blocks use JetBrains Mono.
Shape language is **8–16px radii** with a sweet-spot at 8px for buttons and 16px for feature cards. Buttons round at **8px** (more rounded than Stripe's 6px or WorkOS's 2px, less than Linear's 12px). Inputs at 8px. Cards at 16px. Organization tiles in the multi-tenant dashboard preview round at 12px. The radius scale reads as friendly-modern — softer than enterprise, sharper than consumer.
The signature visual element is the **multi-tenant organization dashboard preview** — a screenshot or live mockup of PropelAuth's actual organization-management UI, showing org switcher, role hierarchies (Admin / Member / Viewer), invitations, and SSO management. This is PropelAuth's brand-defining feature: the marketing page literally shows the multi-tenant interface that competitors don't ship out-of-the-box. Where Clerk shows the live `<SignIn />` component, PropelAuth shows the `<OrganizationDashboard />` — a deeper, more B2B-specific demo.
**Key Characteristics:**
- White canvas (`#ffffff`) with light slate alt sections (`#f8f9fa`, `#f1f3f5`)
- Hero display in **SF Pro Rounded 60/900** (Heavy) — the typographic signature
- Body in Inter 16/400 — modern dev-tool foundation
- Deep-navy `#151531` for headings and primary CTA — Apple-rounded but B2B-serious
- Indigo-violet `#5d5cf5` for brand emphasis — focus ring, eyebrow pills, accent CTA

## 3. Typography Rules
### Font Family
**Display**: `SF Pro Rounded` (Apple, 2017) with `SF Pro Display` as the standard fallback and `SN Pro` as the licensed alternative. SF Pro Rounded is Apple's rounded variant — its terminals soften slightly, giving the type a friendly-Apple-product feel. PropelAuth runs SF Pro Rounded at weight **900 (Heavy)** for hero and h1 — the most distinctive typographic move. h3–h5 step down to 700 (Bold) and 600 (Semibold).
**Body**: `Inter` with the system stack as fallback. Inter handles all body, button, label, and caption sizes at 400, 500, 600.
**Mono**: `JetBrains Mono`, fallback `SF Mono`, `Fira Code`. Used for code blocks.
**OpenType features**: `ss01` enabled on display SF Pro Rounded for the alternate-`a` form (which is the rounded variant's most distinctive glyph).
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | OT Features | Notes |
|------|------|------|--------|-------------|----------------|-------------|-------|
| hero-display | SF Pro Rounded | 80 | 900 | 1.0 | 0 | ss01 | Hero — Heavy weight is the signature |
| h1 | SF Pro Rounded | 60 | 900 | 1.0 | 0 | ss01 | Page title — observed 60/60 |
| h2 | SF Pro Rounded | 40 | 900 | 1.25 | 0 | — | Section opener |
| h3 | SF Pro Rounded | 28 | 700 | 1.30 | -0.005em | — | Sub-section — Bold |
| h4 | SF Pro Rounded | 22 | 700 | 1.35 | -0.005em | — | Feature card title |
| h5 | SF Pro Rounded | 18 | 600 | 1.40 | 0 | — | Sub-feature — Semibold |
| eyebrow | Inter | 12 | 600 | 1.50 | 0.08em uppercase | — | "MULTI-TENANT", "ENTERPRISE READY" |
| body-lg | Inter | 18 | 400 | 1.60 | 0 | — | Hero sub-copy |
| body-md | Inter | 16 | 400 | 1.50 | 0 | — | Default body |
| body-sm | Inter | 14 | 400 | 1.50 | 0 | — | Secondary |
| label | Inter | 13 | 500 | 1.40 | 0 | — | Form labels |
| button-label | Inter | 15 | 600 | 1.0 | 0 | — | CTA text — note 15/600 |
| nav-link | Inter | 15 | 500 | 1.20 | 0 | — | Top nav |
| caption | Inter | 13 | 400 | 1.40 | 0 | — | Captions |
| micro | Inter | 12 | 400 | 1.40 | 0 | — | Footer legal |
| code-inline | JetBrains Mono | 14 | 400 | 1.50 | 0 | — | Inline `<code>` |
| code-block | JetBrains Mono | 13 | 400 | 1.55 | 0 | — | Code panel |
| org-tag | Inter | 12 | 600 | 1.0 | 0 | — | "Acme Inc." organization chip |
| role-badge | Inter | 11 | 700 | 1.0 | 0.04em uppercase | — | "ADMIN", "MEMBER", "VIEWER" |
| quote | SF Pro Rounded | 22 | 400 | 1.40 | -0.005em | italic | Pull quote |
### Principles
- **SF Pro Rounded 900 is the typographic signature.** Heavy weight at large display sizes. Substitute `SN Pro` (similar rounded sans) or fall back to Inter Black at the same metrics. The Apple-product polish is what distinguishes PropelAuth.
- **Two typefaces, two registers.** SF Pro Rounded handles display (display polish), Inter handles body (dev-tool foundation). The split is the brand voice.
- **Display weight steps: 900 → 700 → 600.** Hero/h1/h2 at 900, h3/h4 at 700, h5 at 600. Bold-as-display is the discipline.
- **Near-zero tracking on display.** Most B2B-identity sites use negative tracking; PropelAuth's SF Pro Rounded already reads tight at 900, so tracking stays at 0.
- **Body Inter at 16/400.** Modern dev-tool foundation. No surprises.
- **Eyebrows in body Inter, not display.** 12/600 uppercase Inter — the multi-tenant signature.
- **Role badges at 11/700 uppercase 0.04em tracking.** Tighter and bolder than eyebrows because they communicate critical permission state.
## 4. Component Stylings

**`role-hierarchy-diagram`** — line-art SVG of role hierarchies showing Admin > Member > Viewer relationships. Used in the "Roles & Permissions" feature section.
## 5. Layout Principles
### Spacing System
- Base unit: **4px**
- Scale: `4 · 8 · 12 · 16 · 20 · 24 · 32 · 40 · 48 · 64 · 80 · 96 · 128 · 160`
- Hero padding (vertical): **128px** at desktop
- Section padding: **96–128px** between major sections
- Card internal padding: **32px** for feature cards
- Gutter: **24px** between feature cards in 2-column
### Grid & Container
- Max content width: **1200px** centred
- Hero: full-width with copy capped at 720px prose
- Feature grid: 2-column at desktop with 24px gutter
- Pricing: 3-column tier comparison cards with recommended tier violet-bordered
- Organization dashboard preview: full-width single card
### Whitespace Philosophy
PropelAuth gives sections **modern dev-tool breath** — 96–128px between bands. The hero band is 128px tall. The organization dashboard preview takes a full editorial section to itself, generously padded.
### Section Cadence
The page alternates **white canvas → soft white → white → violet-tinted → white → deep-navy mood-zone → deepest footer**. The deep-navy mood-zone (`#151531`) appears 1–2 times per page for the brand-emphasized "Built for B2B" features. The deepest band (`#0a0a1f`) is the footer.
## 6. Shapes & Radius Scale
| Tier | Value | Use |
|------|-------|-----|
| Micro | 2px | Dense table corners |
| Small | 4px | Organization tags, role badges |
| Default | 6px | Tooltips |
| Standard | 8px | Buttons, inputs, dropdowns |
| Comfortable | 12px | Code blocks, mega-menu, organization cards |
| Card | 16px | Feature cards, modals, pricing |
| Pill | 9999px | Eyebrow pills, status pills |
The 8px button radius is the friendly-modern default. Organization tags and role badges use **4px** (slim rectangle) to read as "data tag" rather than "button". This split is intentional.
## 7. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| 0 — Flat | no shadow | Body sections |
| 1 — Hairline | `1px #dee2e6` border | Cards at rest |
| 2 — Hover | `rgba(21,21,49,0.04) 0 4px 12px` | Hovered cards, mega-menu |
| 3 — Elevated | `rgba(21,21,49,0.08) 0 16px 32px` | Mega-menu, sticky bars |
| 4 — Modal | `rgba(21,21,49,0.16) 0 24px 48px` | Centred dialog |
| 5 — Focus | `0 0 0 2px #5d5cf5` ring | Focused inputs and buttons |
### Shadow Philosophy
PropelAuth's shadows are **deep-navy tinted** (`rgba(21,21,49,...)`). The brand colour as the shadow source ties the elevated surfaces tonally to the page. Most cards have no shadow at rest — depth is the hairline border.
## 8. Interaction & Motion
### Easing
- **Standard**: `cubic-bezier(0.4, 0, 0.2, 1)` — default
- **Emphasized**: `cubic-bezier(0.2, 0, 0, 1)` — modal entry, mega-menu
### Durations
| Bucket | Value | Use |
|--------|-------|-----|
| Fast | 150ms | Hover colour swap, focus ring fade-in |
| Standard | 240ms | Card hover, mega-menu open |
| Slow | 320ms | Modal enter, hero reveal, org-switcher transition |
### Per-Component Recipes
- **CTA hover (primary)**: deep-navy brightens `#151531` → `#1f1f40` over 150ms.
- **CTA hover (violet)**: violet brightens `#5d5cf5` → `#7c7bf7` over 150ms.
- **Card hover**: 1px translateY(-1) + navy-tinted 4% shadow over 240ms; border deepens slightly.
- **Hero reveal**: sections fade-up from `translateY(16px)/opacity 0` → `0/1` over 320ms emphasized.
- **Org-switcher transition**: when user switches organizations, the dashboard preview slides smoothly with 320ms emphasized — multi-tenant signature motion.
- **Mega-menu open**: 240ms fade + 4px slide-down.
- **Modal enter**: scrim fades 240ms; dialog from `translateY(8px)/opacity(0)` → `0/1` over 320ms emphasized.
### Page Transitions
Page-to-page navigation uses no transition — hard navigation.
### Reduced Motion
Respects `prefers-reduced-motion: reduce`. Hero reveal, card hover translateY, and org-switcher transition suppress (opacity-only).
## 9. Accessibility & A11y
### Contrast Pairs
| Pair | Ratio | Level |
|------|-------|-------|
| #343a40 body on #ffffff | 11.7 | AAA |
| #151531 heading on #ffffff | 17.0 | AAA |
| #ffffff on #151531 deep-navy CTA | 17.0 | AAA |
| #ffffff on #5d5cf5 violet CTA | 4.6 | AA at body sizes |
| #5d5cf5 link on #ffffff | 4.6 | AA at body sizes |
| #6c757d muted on #ffffff | 5.5 | AA |
| #dc2626 admin role on #ffe3e3 | 4.7 | AA |
| #0f8a4d member role on #d3f9d8 | 4.6 | AA |
### Focus Indicators
Focus ring is **2px solid `#5d5cf5` (indigo-violet) with 2px outline-offset**. The violet doubles as brand affordance and accessibility indicator.
### ARIA Patterns
- **Top nav**: `role="navigation"`, `aria-label="Primary"`. Mega-menu uses `role="menu"`.
- **Pricing tier cards**: `<h3>` heading, recommended tier `aria-current="recommended"`.
- **Org-switcher**: `role="combobox"` with `role="listbox"` and `role="option"`. `aria-expanded` and `aria-activedescendant`.
- **Role badges**: visible text + screen reader announces "Admin role", "Member role", "Viewer role" via `aria-label`.
- **Modal**: `role="dialog"`, `aria-modal="true"`, focus trap, Esc closes.
- **Code blocks**: `role="region"`, `aria-label="Code example"`. Copy button `aria-live="polite"`.
### Keyboard Navigation
- Tab: logo → product → docs → pricing → customers → log in → primary CTA
- Org-switcher: Enter opens, arrow keys navigate, Enter selects, Esc closes
- Mega-menu: arrow keys navigate, Esc closes
- Modal: focus trap, Tab cycles
- Skip-to-main visible on first Tab
### Screen Reader Hints
- Organization tags announce "Organization: Acme Inc."
- Role badges announce role name and permission level
- Org-switcher announces "Switch organization" and current selection
### Reduced Motion
Hero reveal, card hover translateY, org-switcher transition suppress. Modal slide degrades to fade.
## 10. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Mobile | <640px | Nav collapses to hamburger; hero copy 36px; feature grid 1-up |
| Tablet | 640–1024px | Nav reveals product + log in; feature grid 2-up; org dashboard preview narrows |
| Desktop | 1024–1280px | Full mega-menu; container caps at 1200px |
| Wide | 1280–1440px | Container stays 1200px |
### Touch Targets
- Primary CTAs: 44px height — meets AA
- Nav links: 36×16px tap target at desktop, 44×20 on mobile
- Form inputs: 44px height
- Org-switcher rows: 40px height
### Collapsing Strategy
- Nav: product / docs / customers collapse to hamburger at <1024px
- Hero: 60px → 48px → 36px down breakpoints
- Feature grid: 3-up → 2-up → 1-up
- Pricing: 3-column → 1-column
- Organization dashboard preview: scales down with container queries
### Image Behavior
Organization dashboard preview is a high-fidelity SVG/PNG mockup with retina sources. Customer logos use SVG.
### Container Queries
Used in the organization dashboard preview: when card width drops below ~640px, the side-rail collapses and tabs stack.
## 11. Content & Voice
### Tone
Confident, considered, technically rigorous, B2B-focused. PropelAuth's voice positions auth as **the multi-tenant infrastructure your B2B SaaS needs from day one** — assumes the reader is a founder or senior engineer at an early- to mid-stage B2B SaaS company. Headlines lead with multi-tenant capability ("Authentication for B2B products", "Built for multi-tenant from day one"). The voice acknowledges the gap most auth products leave: "auth is hard, multi-tenant auth is harder, we ship both".
### Microcopy Patterns
- **Button verbs**: "Get started", "Book a demo", "Sign up free", "Try free", "Read the docs"
- **Eyebrow labels**: 12/600 uppercase Inter — "MULTI-TENANT", "B2B READY", "ENTERPRISE"
- **Error message recipe**: precise + actionable — "We couldn't add this user to the organization. Verify their email address or check your seat allowance."
- **Success confirmations**: B2B-specific — "Invitation sent. [Name] will receive an email to join [Organization]."
- **Field labels**: short and exact — "Organization name", "Domain", "Default role"
- **Doc links**: lead with verb — "Read the multi-tenant guide", "View role hierarchy docs"
### Empty States
- Empty organizations: "No organizations yet. Create your first organization to get started with multi-tenant auth."
- Empty members: "No members in this organization. Invite users by email or share a sign-up link."
- Empty roles: "No custom roles yet. Use the default Admin/Member/Viewer or define your own."
### CTA Verb Conventions
- Primary: "Get started", "Sign up free", "Book a demo"
- Secondary: "Read the docs", "Try free", "View pricing"
- Tertiary: "Learn more →", "View changelog"
- Avoided: "Click here", "Submit", "Buy now"
## 12. Dark Mode & Theming
**Light-only on the marketing canvas with deep-navy mood-zone bands.** The deep-navy `#151531` appears in 1–2 brand-emphasized sections per page (typically the "Built for B2B" feature band). The deepest near-black `#0a0a1f` is the footer. No full dark theme on marketing.
### Dark Mood-Zone Treatment
```yaml
bg-dark: '#151531'
bg-deeper: '#252550'
bg-deepest: '#0a0a1f'
text-on-dark: '#ffffff'
text-muted-on-dark: '#adb5bd'
border-on-dark: 'rgba(255,255,255,0.10)'
brand-on-dark: '#7c7bf7' # violet brightens slightly on dark
button-primary-on-dark: '#ffffff' # inverse — white CTA on dark
button-primary-text-on-dark: '#151531'
```
### Component Theming
The PropelAuth-branded components ship with both light and dark themes for embedding in customer apps:
```yaml
component-light:
bg: '#ffffff'
text: '#343a40'
brand: '#5d5cf5'
component-dark:
bg: '#151531'
text: '#ffffff'
brand: '#7c7bf7'
```
## 13. Lineage & Influences
PropelAuth's visual lineage runs through three traditions: **Apple-product-marketing polish** (SF Pro Rounded at Heavy weight is Apple's signature display move — used on Apple's product marketing pages from 2017 onwards); **B2B-multi-tenant-platform aesthetic** (the organization dashboard preview, the role-badge system, the SAML SSO callouts — all moves borrowed from enterprise B2B SaaS canon); and **modern dev-tool foundation** (Inter body, hairline cards, JetBrains Mono code blocks).
The **two-colour brand system** (deep-navy + indigo-violet) is the move that distinguishes PropelAuth. Most auth platforms commit to a single brand colour; PropelAuth's duet — navy for gravitas, violet for emphasis — works because the two operate at different luminance levels and serve different purposes. The role-badge system (Admin red, Member green, Viewer violet) extends this two-colour discipline into the feature surface area.
What PropelAuth rejects: **dark canvases as primary** (light-first with deep-navy mood-zones), **single-colour brand minimalism** (the duet is more expressive), **enterprise blue-trust cliché** (deep-navy with purple undertones), and **photographic product screenshots** (high-fidelity organization dashboard mockups instead).
**Influences:**
- Apple Product Marketing — SF Pro Rounded at Heavy weight, [apple.com](https://apple.com)
- Stripe — confidence-via-restraint, hairline cards, [stripe.com](https://stripe.com)
- Auth0 — predecessor in identity-platform aesthetic; PropelAuth differentiates with B2B-multi-tenant focus, [auth0.com](https://auth0.com)
- Vercel — frosted-glass navbar, restraint discipline, [vercel.com](https://vercel.com)
- WorkOS — B2B-enterprise-ready positioning, [workos.com](https://workos.com)
## 14. Do's and Don'ts
**Do**
- Anchor the canvas on white (`#ffffff`) with light slate alt sections (`#f8f9fa`, `#f1f3f5`)
- Run hero display in **SF Pro Rounded 60/900** (Heavy) — the typographic signature
- Use deep-navy `#151531` for headings, h1, and primary CTA fill
- Use indigo-violet `#5d5cf5` for brand emphasis — focus rings, eyebrow pills, accent CTA
- Maintain the two-colour brand system: deep-navy (gravitas) + indigo-violet (emphasis)
- Build the role-badge system: Admin red, Member green, Viewer violet — multi-tenant signature
- Use 8px button radius, 16px card radius — friendly-modern proportions
- Render the organization dashboard preview as the signature illustration
- Use Inter for all body, button, label, caption — modern dev-tool foundation
- Render code blocks on deep-navy `#151531` ground — matches brand CTA
**Don't**
- Don't substitute Inter for display — SF Pro Rounded 900 is the typographic discipline
- Don't run SF Pro Rounded below weight 700 for display — Heavy is the signature
- Don't introduce a third brand colour — the navy + violet duet is the discipline
- Don't make role badges into pills — 4px slim rectangle reads as data tag
- Don't tighten section padding below 96px — modern dev-tool breath
- Don't use button radius below 6px — 8px is the friendly-modern default
- Don't add atmospheric multi-layer shadows — navy-tinted hairline + 4% hover is the depth strategy
- Don't show photographic product screenshots — high-fidelity mockups of the organization dashboard instead
- Don't use serif type — SF Pro Rounded + Inter is the system
- Don't soften the multi-tenant voice — "organizations", "roles", "RBAC", "SAML SSO" are the brand vocabulary

Primary CTA inverts: white fill, deep-navy text."
### Iteration Guide
1. **SF Pro Rounded 900 is the typographic signature.** This is the most distinctive PropelAuth move. Substitute Inter Black at the same metrics if SF Pro Rounded isn't available.
2. **Two-colour brand: navy + violet.** Deep-navy `#151531` for gravitas (headings, primary CTA, dark sections). Indigo-violet `#5d5cf5` for emphasis (focus, eyebrow pills, accent CTA). Don't merge them into a single colour.
3. **Role-badge system is non-negotiable.** Admin red, Member green, Viewer violet. Communicate role at every multi-tenant moment.
4. **8px button radius / 16px card radius.** Friendly-modern proportions.
5. **Body in Inter, display in SF Pro Rounded.** Two typefaces, two registers — don't unify.
6. **Organization dashboard preview as hero.** The signature illustration is the multi-tenant UI itself.
7. **Deep-navy mood-zones for B2B emphasis.** 1–2 per page max — used for "Built for B2B" feature bands.
8. **Code blocks on deep-navy ground.** Matches brand CTA — ties code presentation to brand.
1. Visual Theme & Atmosphere
PropelAuth’s marketing site is the canonical B2B-multi-tenant auth canvas — a white ground (#ffffff) anchored on body slate (#343a40) with hero display in SF Pro Rounded at 60/900 — a Heavy weight that immediately signals “Apple-marketing polished” while the underlying brand colour deep-navy (#151531) signals “B2B-platform serious”. This combination — Apple-rounded display + deep-navy ink — is the most distinctive type-and-colour pairing in the auth space. The page reads as a B2B-multi-tenant platform built by founders who care about polish: confident, considered, slightly playful in the type, completely rigorous in the feature set.
The chromatic system is white + deep-navy + indigo-violet. The canvas is pure #ffffff. Body text runs in #343a40 (slate, slightly warmer than gray). Display headlines and the primary CTA fill use #151531 deep-navy — a confident dark indigo that has slight purple undertones, reading as enterprise without enterprise-blue cliché. The accent colour is #5d5cf5 indigo-violet — used for the brand mark, focus rings, eyebrow pills, role-viewer badges, and brand-emphasized “Try free” CTAs. Where most B2B-identity sites use a single brand colour, PropelAuth maintains a two-colour brand system: deep-navy carries the gravitas, violet carries the brand emphasis. The two work as a duet rather than competing.
Type runs SF Pro Rounded for display and Inter for body. SF Pro Rounded is Apple’s rounded variant of SF Pro Display — used here at weight 900 (Heavy) for hero copy and h1, weight 700 for h3/h4, and 600 for h5. The 900 weight is the typographic signature: it’s heavier than any conventional B2B-identity display weight (most run 500–700), and it gives the page a distinctly Apple-marketing-polished feel that distinguishes PropelAuth from Inter-default peers like WorkOS, Clerk, and Stytch. Body type is Inter at 16/400. Code blocks use JetBrains Mono.
Shape language is 8–16px radii with a sweet-spot at 8px for buttons and 16px for feature cards. Buttons round at 8px (more rounded than Stripe’s 6px or WorkOS’s 2px, less than Linear’s 12px). Inputs at 8px. Cards at 16px. Organization tiles in the multi-tenant dashboard preview round at 12px. The radius scale reads as friendly-modern — softer than enterprise, sharper than consumer.
The signature visual element is the multi-tenant organization dashboard preview — a screenshot or live mockup of PropelAuth’s actual organization-management UI, showing org switcher, role hierarchies (Admin / Member / Viewer), invitations, and SSO management. This is PropelAuth’s brand-defining feature: the marketing page literally shows the multi-tenant interface that competitors don’t ship out-of-the-box. Where Clerk shows the live <SignIn /> component, PropelAuth shows the <OrganizationDashboard /> — a deeper, more B2B-specific demo.

3. Typography Rules
Font Family
Display: SF Pro Rounded (Apple, 2017) with SF Pro Display as the standard fallback and SN Pro as the licensed alternative. SF Pro Rounded is Apple’s rounded variant — its terminals soften slightly, giving the type a friendly-Apple-product feel. PropelAuth runs SF Pro Rounded at weight 900 (Heavy) for hero and h1 — the most distinctive typographic move. h3–h5 step down to 700 (Bold) and 600 (Semibold).
Body: Inter with the system stack as fallback. Inter handles all body, button, label, and caption sizes at 400, 500, 600.
Mono: JetBrains Mono, fallback SF Mono, Fira Code. Used for code blocks.
OpenType features: ss01 enabled on display SF Pro Rounded for the alternate-a form (which is the rounded variant’s most distinctive glyph).

Principles
- SF Pro Rounded 900 is the typographic signature. Heavy weight at large display sizes. Substitute
SN Pro(similar rounded sans) or fall back to Inter Black at the same metrics. The Apple-product polish is what distinguishes PropelAuth. - Two typefaces, two registers. SF Pro Rounded handles display (display polish), Inter handles body (dev-tool foundation). The split is the brand voice.
- Display weight steps: 900 → 700 → 600. Hero/h1/h2 at 900, h3/h4 at 700, h5 at 600. Bold-as-display is the discipline.
- Near-zero tracking on display. Most B2B-identity sites use negative tracking; PropelAuth’s SF Pro Rounded already reads tight at 900, so tracking stays at 0.
- Body Inter at 16/400. Modern dev-tool foundation. No surprises.
- Eyebrows in body Inter, not display. 12/600 uppercase Inter — the multi-tenant signature.
- Role badges at 11/700 uppercase 0.04em tracking. Tighter and bolder than eyebrows because they communicate critical permission state.

5. Layout Principles
Spacing System
- Base unit: 4px
- Scale:
4 · 8 · 12 · 16 · 20 · 24 · 32 · 40 · 48 · 64 · 80 · 96 · 128 · 160 - Hero padding (vertical): 128px at desktop
- Section padding: 96–128px between major sections
- Card internal padding: 32px for feature cards
- Gutter: 24px between feature cards in 2-column
Grid & Container
- Max content width: 1200px centred
- Hero: full-width with copy capped at 720px prose
- Feature grid: 2-column at desktop with 24px gutter
- Pricing: 3-column tier comparison cards with recommended tier violet-bordered
- Organization dashboard preview: full-width single card
Whitespace Philosophy
PropelAuth gives sections modern dev-tool breath — 96–128px between bands. The hero band is 128px tall. The organization dashboard preview takes a full editorial section to itself, generously padded.
Section Cadence
The page alternates white canvas → soft white → white → violet-tinted → white → deep-navy mood-zone → deepest footer. The deep-navy mood-zone (#151531) appears 1–2 times per page for the brand-emphasized “Built for B2B” features. The deepest band (#0a0a1f) is the footer.
6. Shapes & Radius Scale
| Tier | Value | Use |
|---|---|---|
| Micro | 2px | Dense table corners |
| Small | 4px | Organization tags, role badges |
| Default | 6px | Tooltips |
| Standard | 8px | Buttons, inputs, dropdowns |
| Comfortable | 12px | Code blocks, mega-menu, organization cards |
| Card | 16px | Feature cards, modals, pricing |
| Pill | 9999px | Eyebrow pills, status pills |
The 8px button radius is the friendly-modern default. Organization tags and role badges use 4px (slim rectangle) to read as “data tag” rather than “button”. This split is intentional.
7. Depth & Elevation
| Level | Treatment | Use |

Shadow Philosophy
PropelAuth’s shadows are deep-navy tinted (rgba(21,21,49,...)). The brand colour as the shadow source ties the elevated surfaces tonally to the page. Most cards have no shadow at rest — depth is the hairline border.
8. Interaction & Motion
Easing
- Standard:
cubic-bezier(0.4, 0, 0.2, 1)— default - Emphasized:
cubic-bezier(0.2, 0, 0, 1)— modal entry, mega-menu
Durations
| Bucket | Value | Use |
|---|---|---|
| Fast | 150ms | Hover colour swap, focus ring fade-in |
| Standard | 240ms | Card hover, mega-menu open |
| Slow | 320ms | Modal enter, hero reveal, org-switcher transition |
Per-Component Recipes
- CTA hover (primary): deep-navy brightens
#151531→#1f1f40over 150ms. - CTA hover (violet): violet brightens
#5d5cf5→#7c7bf7over 150ms. - Card hover: 1px translateY(-1) + navy-tinted 4% shadow over 240ms; border deepens slightly.
- Hero reveal: sections fade-up from
translateY(16px)/opacity 0→0/1over 320ms emphasized. - Org-switcher transition: when user switches organizations, the dashboard preview slides smoothly with 320ms emphasized — multi-tenant signature motion.
- Mega-menu open: 240ms fade + 4px slide-down.
- Modal enter: scrim fades 240ms; dialog from
translateY(8px)/opacity(0)→0/1over 320ms emphasized.
Page Transitions
Page-to-page navigation uses no transition — hard navigation.
Reduced Motion
Respects prefers-reduced-motion: reduce. Hero reveal, card hover translateY, and org-switcher transition suppress (opacity-only).
9. Accessibility & A11y
Contrast Pairs
| Pair | Ratio | Level |
|---|---|---|
| #343a40 body on #ffffff | 11.7 | AAA |
| #151531 heading on #ffffff | 17.0 | AAA |
| #ffffff on #151531 deep-navy CTA | 17.0 | AAA |
| #ffffff on #5d5cf5 violet CTA | 4.6 | AA at body sizes |
| #5d5cf5 link on #ffffff | 4.6 | AA at body sizes |
| #6c757d muted on #ffffff | 5.5 | AA |
| #dc2626 admin role on #ffe3e3 | 4.7 | AA |
| #0f8a4d member role on #d3f9d8 | 4.6 | AA |
Focus Indicators
Focus ring is 2px solid #5d5cf5 (indigo-violet) with 2px outline-offset. The violet doubles as brand affordance and accessibility indicator.
ARIA Patterns
- Top nav:
role="navigation",aria-label="Primary". Mega-menu usesrole="menu". - Pricing tier cards:
<h3>heading, recommended tieraria-current="recommended". - Org-switcher:
role="combobox"withrole="listbox"androle="option".aria-expandedandaria-activedescendant. - Role badges: visible text + screen reader announces “Admin role”, “Member role”, “Viewer role” via
aria-label. - Modal:
role="dialog",aria-modal="true", focus trap, Esc closes. - Code blocks:
role="region",aria-label="Code example". Copy buttonaria-live="polite".
Keyboard Navigation
- Tab: logo → product → docs → pricing → customers → log in → primary CTA
- Org-switcher: Enter opens, arrow keys navigate, Enter selects, Esc closes
- Mega-menu: arrow keys navigate, Esc closes
- Modal: focus trap, Tab cycles
- Skip-to-main visible on first Tab
Screen Reader Hints
- Organization tags announce “Organization: Acme Inc.”
- Role badges announce role name and permission level
- Org-switcher announces “Switch organization” and current selection
Reduced Motion
Hero reveal, card hover translateY, org-switcher transition suppress. Modal slide degrades to fade.
10. Responsive Behavior
Breakpoints
| Name | Width | Key Changes |
|---|---|---|
| Mobile | <640px | Nav collapses to hamburger; hero copy 36px; feature grid 1-up |
| Tablet | 640–1024px | Nav reveals product + log in; feature grid 2-up; org dashboard preview narrows |
| Desktop | 1024–1280px | Full mega-menu; container caps at 1200px |
| Wide | 1280–1440px | Container stays 1200px |
Touch Targets
- Primary CTAs: 44px height — meets AA
- Nav links: 36×16px tap target at desktop, 44×20 on mobile
- Form inputs: 44px height
- Org-switcher rows: 40px height
Collapsing Strategy
- Nav: product / docs / customers collapse to hamburger at <1024px
- Hero: 60px → 48px → 36px down breakpoints
- Feature grid: 3-up → 2-up → 1-up
- Pricing: 3-column → 1-column
- Organization dashboard preview: scales down with container queries
Image Behavior
Organization dashboard preview is a high-fidelity SVG/PNG mockup with retina sources. Customer logos use SVG.
Container Queries
Used in the organization dashboard preview: when card width drops below ~640px, the side-rail collapses and tabs stack.
11. Content & Voice
Tone
Confident, considered, technically rigorous, B2B-focused. PropelAuth’s voice positions auth as the multi-tenant infrastructure your B2B SaaS needs from day one — assumes the reader is a founder or senior engineer at an early- to mid-stage B2B SaaS company. Headlines lead with multi-tenant capability (“Authentication for B2B products”, “Built for multi-tenant from day one”). The voice acknowledges the gap most auth products leave: “auth is hard, multi-tenant auth is harder, we ship both”.
Microcopy Patterns
- Button verbs: “Get started”, “Book a demo”, “Sign up free”, “Try free”, “Read the docs”
- Eyebrow labels: 12/600 uppercase Inter — “MULTI-TENANT”, “B2B READY”, “ENTERPRISE”
- Error message recipe: precise + actionable — “We couldn’t add this user to the organization. Verify their email address or check your seat allowance.”
- Success confirmations: B2B-specific — “Invitation sent. [Name] will receive an email to join [Organization].”
- Field labels: short and exact — “Organization name”, “Domain”, “Default role”
- Doc links: lead with verb — “Read the multi-tenant guide”, “View role hierarchy docs”
Empty States
- Empty organizations: “No organizations yet. Create your first organization to get started with multi-tenant auth.”
- Empty members: “No members in this organization. Invite users by email or share a sign-up link.”
- Empty roles: “No custom roles yet. Use the default Admin/Member/Viewer or define your own.”
CTA Verb Conventions
- Primary: “Get started”, “Sign up free”, “Book a demo”
- Secondary: “Read the docs”, “Try free”, “View pricing”
- Tertiary: “Learn more →”, “View changelog”
- Avoided: “Click here”, “Submit”, “Buy now”
12. Dark Mode & Theming
Light-only on the marketing canvas with deep-navy mood-zone bands. The deep-navy #151531 appears in 1–2 brand-emphasized sections per page (typically the “Built for B2B” feature band). The deepest near-black #0a0a1f is the footer. No full dark theme on marketing.

PropelAuth’s visual lineage runs through three traditions: Apple-product-marketing polish (SF Pro Rounded at Heavy weight is Apple’s signature display move — used on Apple’s product marketing pages from 2017 onwards); B2B-multi-tenant-platform aesthetic (the organization dashboard preview, the role-badge system, the SAML SSO callouts — all moves borrowed from enterprise B2B SaaS canon); and modern dev-tool foundation (Inter body, hairline cards, JetBrains Mono code blocks).
The two-colour brand system (deep-navy + indigo-violet) is the move that distinguishes PropelAuth. Most auth platforms commit to a single brand colour; PropelAuth’s duet — navy for gravitas, violet for emphasis — works because the two operate at different luminance levels and serve different purposes. The role-badge system (Admin red, Member green, Viewer violet) extends this two-colour discipline into the feature surface area.
What PropelAuth rejects: dark canvases as primary (light-first with deep-navy mood-zones), single-colour brand minimalism (the duet is more expressive), enterprise blue-trust cliché (deep-navy with purple undertones), and photographic product screenshots (high-fidelity organization dashboard mockups instead).
Influences:
- Apple Product Marketing — SF Pro Rounded at Heavy weight, apple.com
- Stripe — confidence-via-restraint, hairline cards, stripe.com
- Auth0 — predecessor in identity-platform aesthetic; PropelAuth differentiates with B2B-multi-tenant focus, auth0.com
- Vercel — frosted-glass navbar, restraint discipline, vercel.com
- WorkOS — B2B-enterprise-ready positioning, workos.com
14. Do’s and Don’ts
Do
- Anchor the canvas on white (
#ffffff) with light slate alt sections (#f8f9fa,#f1f3f5) - Run hero display in SF Pro Rounded 60/900 (Heavy) — the typographic signature
- Use deep-navy
#151531for headings, h1, and primary CTA fill - Use indigo-violet
#5d5cf5for brand emphasis — focus rings, eyebrow pills, accent CTA - Maintain the two-colour brand system: deep-navy (gravitas) + indigo-violet (emphasis)
- Build the role-badge system: Admin red, Member green, Viewer violet — multi-tenant signature
- Use 8px button radius, 16px card radius — friendly-modern proportions
- Render the organization dashboard preview as the signature illustration
- Use Inter for all body, button, label, caption — modern dev-tool foundation
- Render code blocks on deep-navy
#151531ground — matches brand CTA
Don’t
- Don’t substitute Inter for display — SF Pro Rounded 900 is the typographic discipline
- Don’t run SF Pro Rounded below weight 700 for display — Heavy is the signature
- Don’t introduce a third brand colour — the navy + violet duet is the discipline
- Don’t make role badges into pills — 4px slim rectangle reads as data tag
- Don’t tighten section padding below 96px — modern dev-tool breath
- Don’t use button radius below 6px — 8px is the friendly-modern default
- Don’t add atmospheric multi-layer shadows — navy-tinted hairline + 4% hover is the depth strategy
- Don’t show photographic product screenshots — high-fidelity mockups of the organization dashboard instead
- Don’t use serif type — SF Pro Rounded + Inter is the system
- Don’t soften the multi-tenant voice — “organizations”, “roles”, “RBAC”, “SAML SSO” are the brand vocabulary

Iteration Guide
- SF Pro Rounded 900 is the typographic signature. This is the most distinctive PropelAuth move. Substitute Inter Black at the same metrics if SF Pro Rounded isn’t available.
- Two-colour brand: navy + violet. Deep-navy
#151531for gravitas (headings, primary CTA, dark sections). Indigo-violet#5d5cf5for emphasis (focus, eyebrow pills, accent CTA). Don’t merge them into a single colour. - Role-badge system is non-negotiable. Admin red, Member green, Viewer violet. Communicate role at every multi-tenant moment.
- 8px button radius / 16px card radius. Friendly-modern proportions.
- Body in Inter, display in SF Pro Rounded. Two typefaces, two registers — don’t unify.
- Organization dashboard preview as hero. The signature illustration is the multi-tenant UI itself.
- Deep-navy mood-zones for B2B emphasis. 1–2 per page max — used for “Built for B2B” feature bands.
- Code blocks on deep-navy ground. Matches brand CTA — ties code presentation to brand.
