Design System Inspired by 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

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

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

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

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
