# Design System: Cohere
## 1. Visual Theme & Atmosphere
Cohere's interface is a polished enterprise command deck — confident, clean, and designed to make AI feel like serious infrastructure rather than a consumer toy. The experience lives on a bright white canvas where content is organized into generously rounded cards (22px radius) that create an organic, cloud-like containment language. This is a site that speaks to CTOs and enterprise architects: professional without being cold, sophisticated without being intimidating.
The design language bridges two worlds with a dual-typeface system: CohereText, a custom display serif with tight tracking, gives headlines the gravitas of a technology manifesto, while Unica77 Cohere Web handles all body and UI text with geometric Swiss precision. This serif/sans pairing creates a "confident authority meets engineering clarity" personality that perfectly reflects an enterprise AI platform.
Color is used with extreme restraint — the interface is almost entirely black-and-white with cool gray borders (`#d9d9dd`, `#e5e7eb`). Purple-violet appears only in photographic hero bands, gradient sections, and the interactive blue (`#1863dc`) that signals hover and focus states. This chromatic restraint means that when color DOES appear — in product screenshots, enterprise photography, and the deep purple section — it carries maximum visual weight.
**Key Characteristics:**
- Bright white canvas with cool gray containment borders
- 22px signature border-radius — the distinctive "Cohere card" roundness
- Dual custom typeface: CohereText (display serif) + Unica77 (body sans)
- Enterprise-grade chromatic restraint: black, white, cool grays, minimal purple-blue accent
- Deep purple/violet hero sections providing dramatic contrast
- Ghost/transparent buttons that shift to blue on hover
- Enterprise photography showing diverse real-world applications
- CohereMono for code and technical labels with uppercase transforms
## 2. Color Palette & Roles
### Primary
- **Cohere Black** (`#000000`): Primary headline text and maximum-emphasis elements.
- **Near Black** (`#212121`): Standard body link color — slightly softer than pure black.
- **Deep Dark** (`#17171c`): A blue-tinted near-black for navigation and dark-section text.
### Secondary & Accent
- **Interaction Blue** (`#1863dc`): The primary interactive accent — appears on button hover, focus states, and active links. The sole chromatic action color.
- **Ring Blue** (`#4c6ee6` at 50%): Tailwind ring color for keyboard focus indicators.
- **Focus Purple** (`#9b60aa`): Input focus border color — a muted violet.
### Surface & Background
- **Pure White** (`#ffffff`): The primary page background and card surface.
- **Snow** (`#fafafa`): Subtle elevated surfaces and light-section backgrounds.
- **Lightest Gray** (`#f2f2f2`): Card borders and the softest containment lines.
### Neutrals & Text
- **Muted Slate** (`#93939f`): De-emphasized footer links and tertiary text — a cool-toned gray with a slight blue-violet tint.
- **Border Cool** (`#d9d9dd`): Standard section and list-item borders — a cool, slightly purple-tinted gray.
- **Border Light** (`#e5e7eb`): Lighter border variant — Tailwind's standard gray-200.
### Gradient System
- **Purple-Violet Hero Band**: Deep purple gradient sections that create dramatic contrast against the white canvas. These appear as full-width bands housing product screenshots and key messaging.
- **Dark Footer Gradient**: The page transitions through deep purple/charcoal to the black footer, creating a "dusk" effect.
## 3. Typography Rules
### Font Family
- **Display**: `CohereText`, with fallbacks: `Space Grotesk, Inter, ui-sans-serif, system-ui`
- **Body / UI**: `Unica77 Cohere Web`, with fallbacks: `Inter, Arial, ui-sans-serif, system-ui`
- **Code**: `CohereMono`, with fallbacks: `Arial, ui-sans-serif, system-ui`
- **Icons**: `CohereIconDefault` (custom icon font)
### Hierarchy
| Role | Font | Size | Weight | Line Height | Letter Spacing | Notes |
|------|------|------|--------|-------------|----------------|-------|
| Display / Hero | CohereText | 72px (4.5rem) | 400 | 1.00 (tight) | -1.44px | Maximum impact, serif authority |
| Display Secondary | CohereText | 60px (3.75rem) | 400 | 1.00 (tight) | -1.2px | Large section headings |
| Section Heading | Unica77 | 48px (3rem) | 400 | 1.20 (tight) | -0.48px | Feature section titles |
| Sub-heading | Unica77 | 32px (2rem) | 400 | 1.20 (tight) | -0.32px | Card headings, feature names |
| Feature Title | Unica77 | 24px (1.5rem) | 400 | 1.30 | normal | Smaller section titles |
| Body Large | Unica77 | 18px (1.13rem) | 400 | 1.40 | normal | Intro paragraphs |
| Body / Button | Unica77 | 16px (1rem) | 400 | 1.50 | normal | Standard body, button text |
| Button Medium | Unica77 | 14px (0.88rem) | 500 | 1.71 (relaxed) | normal | Smaller buttons, emphasized labels |
| Caption | Unica77 | 14px (0.88rem) | 400 | 1.40 | normal | Metadata, descriptions |
| Uppercase Label | Unica77 / CohereMono | 14px (0.88rem) | 400 | 1.40 | 0.28px | Uppercase section labels |
| Small | Unica77 | 12px (0.75rem) | 400 | 1.40 | normal | Smallest text, footer links |
| Code Micro | CohereMono | 8px (0.5rem) | 400 | 1.40 | 0.16px | Tiny uppercase code labels |
### Principles
- **Serif for declaration, sans for utility**: CohereText carries the brand voice at display scale — its serif terminals give headlines the authority of published research. Unica77 handles everything functional with Swiss-geometric neutrality.
- **Negative tracking at scale**: CohereText uses -1.2px to -1.44px letter-spacing at 60–72px, creating dense, impactful text blocks.
- **Single body weight**: Nearly all Unica77 usage is weight 400. Weight 500 appears only for small button emphasis. The system relies on size and spacing, not weight contrast.
- **Uppercase code labels**: CohereMono uses uppercase with positive letter-spacing (0.16–0.28px) for technical tags and section markers.
## 4. Component Stylings
### Buttons
**Ghost / Transparent**
- Background: transparent (`rgba(255, 255, 255, 0)`)
- Text: Cohere Black (`#000000`)
- No border visible
- Hover: text shifts to Interaction Blue (`#1863dc`), opacity 0.8
- Focus: solid 2px outline in Interaction Blue
- The primary button style — invisible until interacted with
**Dark Solid**
- Background: dark/black
- Text: Pure White
- For CTA on light surfaces
- Pill-shaped or standard radius
**Outlined**
- Border-based containment
- Used in secondary actions
### Cards & Containers
- Background: Pure White (`#ffffff`)
- Border: thin solid Lightest Gray (`1px solid #f2f2f2`) for subtle cards; Cool Border (`#d9d9dd`) for emphasized
- Radius: **22px** — the signature Cohere radius for primary cards, images, and dialog containers. Also 4px, 8px, 16px, 20px for smaller elements
- Shadow: minimal — Cohere relies on background color and borders rather than shadows
- Special: `0px 0px 22px 22px` radius (bottom-only rounding) for section containers
- Dialog: 8px radius for modal/dialog boxes
### Inputs & Forms
- Text: white on dark input, black on light
- Focus border: Focus Purple (`#9b60aa`) with `1px solid`
- Focus shadow: red ring (`rgb(179, 0, 0) 0px 0px 0px 2px`) — likely for error state indication
- Focus outline: Interaction Blue solid 2px
### Navigation
- Clean horizontal nav on white or dark background
- Logo: Cohere wordmark (custom SVG)
- Links: Dark text at 16px Unica77
- CTA: Dark solid button
- Mobile: hamburger collapse
### Image Treatment
- Enterprise photography with diverse subjects and environments
- Purple-tinted hero photography for dramatic sections
- Product UI screenshots on dark surfaces
- Images with 22px radius matching card system
- Full-bleed purple gradient sections
### Distinctive Components
**22px Card System**
- The 22px border-radius is Cohere's visual signature
- All primary cards, images, and containers use this radius
- Creates a cloud-like, organic softness that's distinctive from the typical 8–12px
**Enterprise Trust Bar**
- Company logos displayed in a horizontal strip
- Demonstrates enterprise adoption
- Clean, monochrome logo treatment
**Purple Hero Bands**
- Full-width deep purple sections housing product showcases
- Create dramatic visual breaks in the white page flow
- Product screenshots float within the purple environment
**Uppercase Code Tags**
- CohereMono in uppercase with letter-spacing
- Used as section markers and categorization labels
- Creates a technical, structured information hierarchy
## 5. Layout Principles
### Spacing System
- Base unit: 8px
- Scale: 2px, 6px, 8px, 10px, 12px, 16px, 20px, 22px, 24px, 28px, 32px, 36px, 40px, 56px, 60px
- Button padding varies by variant
- Card internal padding: approximately 24–32px
- Section vertical spacing: generous (56–60px between sections)
### Grid & Container
- Max container width: up to 2560px (very wide) with responsive scaling
- Hero: centered with dramatic typography
- Feature sections: multi-column card grids
- Enterprise sections: full-width purple bands
- 26 breakpoints detected — extremely granular responsive system
### Whitespace Philosophy
- **Enterprise clarity**: Each section presents one clear proposition with breathing room between.
- **Photography as hero**: Large photographic sections provide visual interest without requiring decorative design elements.
- **Card grouping**: Related content is grouped into 22px-rounded cards, creating natural information clusters.
### Border Radius Scale
- Sharp (4px): Navigation elements, small tags, pagination
- Comfortable (8px): Dialog boxes, secondary containers, small cards
- Generous (16px): Featured containers, medium cards
- Large (20px): Large feature cards
- Signature (22px): Primary cards, hero images, main containers — THE Cohere radius
- Pill (9999px): Buttons, tags, status indicators
## 6. Depth & Elevation
| Level | Treatment | Use |
|-------|-----------|-----|
| Flat (Level 0) | No shadow, no border | Page background, text blocks |
| Bordered (Level 1) | `1px solid #f2f2f2` or `#d9d9dd` | Standard cards, list separators |
| Purple Band (Level 2) | Full-width dark purple background | Hero sections, feature showcases |
**Shadow Philosophy**: Cohere is nearly shadow-free. Depth is communicated through **background color contrast** (white cards on purple bands, white surface on snow), **border containment** (cool gray borders), and the dramatic **light-to-dark section alternation**. When elements need elevation, they achieve it through being white-on-dark rather than through shadow casting.
## 7. Do's and Don'ts
### Do
- Use 22px border-radius on all primary cards and containers — it's the visual signature
- Use CohereText for display headings (72px, 60px) with negative letter-spacing
- Use Unica77 for all body and UI text at weight 400
- Keep the palette black-and-white with cool gray borders
- Use Interaction Blue (#1863dc) only for hover/focus interactive states
- Use deep purple sections for dramatic visual breaks and product showcases
- Apply uppercase + letter-spacing on CohereMono for section labels
- Maintain enterprise-appropriate photography with diverse subjects
### Don't
- Don't use border-radius other than 22px on primary cards — the signature radius matters
- Don't introduce warm colors — the palette is strictly cool-toned
- Don't use heavy shadows — depth comes from color contrast and borders
- Don't use bold (700+) weight on body text — 400–500 is the range
- Don't skip the serif/sans hierarchy — CohereText for headlines, Unica77 for body
- Don't use purple as a surface color for cards — purple is reserved for full-width sections
- Don't reduce section spacing below 40px — enterprise layouts need breathing room
- Don't use decoration on buttons by default — ghost/transparent is the base state
## 8. Responsive Behavior
### Breakpoints
| Name | Width | Key Changes |
|------|-------|-------------|
| Small Mobile | <425px | Compact layout, minimal spacing |
| Mobile | 425–640px | Single column, stacked cards |
| Large Mobile | 640–768px | Minor spacing adjustments |
| Tablet | 768–1024px | 2-column grids begin |
| Desktop | 1024–1440px | Full multi-column layout |
| Large Desktop | 1440–2560px | Maximum container width |
*26 breakpoints detected — one of the most granularly responsive sites in the dataset.*
### Touch Targets
- Buttons adequately sized for touch interaction
- Navigation links with comfortable spacing
- Card surfaces as touch targets
### Collapsing Strategy
- **Navigation**: Full nav collapses to hamburger
- **Feature grids**: Multi-column → 2-column → single column
- **Hero text**: 72px → 48px → 32px progressive scaling
- **Purple sections**: Maintain full-width, content stacks
- **Card grids**: 3 → 2 → 1 column
### Image Behavior
- Photography scales proportionally within 22px-radius containers
- Product screenshots maintain aspect ratio
- Purple sections scale background proportionally
## 9. Agent Prompt Guide
### Quick Color Reference
- Primary Text: "Cohere Black (#000000)"
- Page Background: "Pure White (#ffffff)"
- Secondary Text: "Near Black (#212121)"
- Hover Accent: "Interaction Blue (#1863dc)"
- Muted Text: "Muted Slate (#93939f)"
- Card Borders: "Lightest Gray (#f2f2f2)"
- Section Borders: "Border Cool (#d9d9dd)"
### Example Component Prompts
- "Create a hero section on Pure White (#ffffff) with CohereText at 72px weight 400, line-height 1.0, letter-spacing -1.44px. Cohere Black text. Subtitle in Unica77 at 18px weight 400, line-height 1.4."
- "Design a feature card with 22px border-radius, 1px solid Lightest Gray (#f2f2f2) border on white. Title in Unica77 at 32px, letter-spacing -0.32px. Body in Unica77 at 16px, Muted Slate (#93939f)."
- "Build a ghost button: transparent background, Cohere Black text in Unica77 at 16px. On hover, text shifts to Interaction Blue (#1863dc) with 0.8 opacity. Focus: 2px solid Interaction Blue outline."
- "Create a deep purple full-width section with white text. CohereText at 60px for the heading. Product screenshot floats within using 22px border-radius."
- "Design a section label using CohereMono at 14px, uppercase, letter-spacing 0.28px. Muted Slate (#93939f) text."
### Iteration Guide
1. Focus on ONE component at a time
2. Always use 22px radius for primary cards — "the Cohere card roundness"
3. Specify the typeface — CohereText for headlines, Unica77 for body, CohereMono for labels
4. Interactive elements use Interaction Blue (#1863dc) on hover only
5. Keep surfaces white with cool gray borders — no warm tones
6. Purple is for full-width sections, never card backgrounds
