Coinbase Design System

Overview

Coinbase reads like an institutional financial brand that happens to trade crypto — the marketing surfaces are quiet, white-canvas, editorially-spaced, and almost monochromatic. The single brand voltage is Coinbase Blue ({colors.primary} — #0052ff), used scarcely: every primary CTA pill, the brand wordmark, and inline emphasis links. Beyond that one blue, the system is white canvas + ink + soft gray elevation bands + a deep near-black editorial canvas ({colors.surface-dark} — #0a0b0d) for full-bleed product-mockup heroes.

Type pairs CoinbaseDisplay for hero headlines with CoinbaseSans for body, captions, and navigation. Display sits at weight 400 — not the 700+ typical of trading platforms. The choice signals editorial calm and institutional trust rather than fintech urgency.

The page rhythm rotates three modes: bright white editorial sections, soft-gray elevation bands, and full-bleed dark editorial heroes carrying layered product-UI mockup cards. The dark hero with floating dashboard mockups is the single most distinctive component.

Key Characteristics:

• Single accent color: {colors.primary} (#0052ff Coinbase Blue) carries every primary CTA, wordmark, and inline brand link. Used scarcely.
• Modest display weights — CoinbaseDisplay at weight 400, never 700+.
• Editorial pill geometry: every CTA is {rounded.pill} (100px), every asset glyph is {rounded.full}, every card is {rounded.xl} (24px). Sharp corners absent.
• Full-bleed dark heroes with floating product-UI cards: {component.hero-band-dark} plus inline {component.product-ui-card-dark} mockups is the brand's strongest signature pattern.
• Trading semantics: {colors.semantic-up} (#05b169) and {colors.semantic-down} (#cf202f) — text color only, never background fills.
• 96px section rhythm — generous editorial pacing.

Colors

Brand & Accent

• Coinbase Blue ({colors.primary} — #0052ff): The single brand color. Every primary CTA pill, the Coinbase wordmark, and inline brand links.
• Coinbase Blue Active ({colors.primary-active} — #003ecc): Press-state darken on the primary pill.
• Coinbase Blue Disabled ({colors.primary-disabled} — #a8b8cc): Faded-blue tint for disabled CTAs.
• Accent Yellow ({colors.accent-yellow} — #f4b000): A small sub-brand accent used very sparingly on Bitcoin/asset glyph fills inside feature cards. Illustrative-only, not an action color.

Surface

• Canvas ({colors.canvas} — #ffffff): The default page floor.
• Surface Soft ({colors.surface-soft} — #f7f7f7): Subtle alternating band surface.
• Surface Strong ({colors.surface-strong} — #eef0f3): The light-gray fill behind secondary buttons, search pills, asset-icon plates.
• Surface Dark ({colors.surface-dark} — #0a0b0d): Deep near-black canvas for full-bleed dark heroes, CTA bands. Same hex as {colors.ink} — page-floor and text-color share the value.
• Surface Dark Elevated ({colors.surface-dark-elevated} — #16181c): One step lighter, used for floating product-UI mockup cards inside dark heroes.

Hairlines

• Hairline ({colors.hairline} — #dee1e6): Default 1px divider on white surfaces.
• Hairline Soft ({colors.hairline-soft} — #eef0f3): Lighter divider — same hex as {colors.surface-strong}.

Text

• Ink ({colors.ink} — #0a0b0d): Display headings, primary nav, body emphasis.
• Body ({colors.body} — #5b616e): Default running-text — slightly cool gray.
• Body Strong ({colors.body-strong} — #0a0b0d): Same as ink, used for stronger emphasis.
• Muted ({colors.muted} — #7c828a): Sub-titles, breadcrumbs, footer secondary.
• Muted Soft ({colors.muted-soft} — #a8acb3): Disabled link text.
• On Primary ({colors.on-primary} — #ffffff): White text on Coinbase Blue CTAs.
• On Dark ({colors.on-dark} — #ffffff): White text on dark heroes.
• On Dark Soft ({colors.on-dark-soft} — #a8acb3): Muted off-white for secondary text on dark.

Trading Semantics

• Semantic Up ({colors.semantic-up} — #05b169): "Price up" green, text color only.
• Semantic Down ({colors.semantic-down} — #cf202f): "Price down" red, text color only.

Typography

Font Family

The system runs CoinbaseDisplay (display headlines), CoinbaseSans (body, navigation, captions, buttons), CoinbaseIcons (icon font), and CoinbaseMono for tabular numerical data. Fallback stack: -apple-system, system-ui, "Segoe UI", Roboto, Helvetica, Arial, sans-serif.

The display/body split is functional: CoinbaseDisplay carries hero headlines only; CoinbaseSans carries everything else.

Hierarchy

Principles

• Display weight stays at 400. The single most distinctive typographic choice — signals "calm institutional brand" rather than "trading-platform urgency."
• Negative letter-spacing on display only. Display uses -1px to -2px tracking; body stays at 0.
• CoinbaseMono on every number. Asset prices, percent changes — anything tabular renders in CoinbaseMono.

Note on Font Substitutes

CoinbaseDisplay, CoinbaseSans, and CoinbaseMono are licensed Coinbase typefaces.

• CoinbaseDisplay → Inter at weight 400, letter-spacing -1.5%.
• CoinbaseSans → Inter at weight 400/600.
• CoinbaseMono → JetBrains Mono or Geist Mono at weight 500.

Layout

Spacing System

• Base unit: 4px.
• Tokens: {spacing.xxs} 4px · {spacing.xs} 8px · {spacing.sm} 12px · {spacing.base} 16px · {spacing.md} 20px · {spacing.lg} 24px · {spacing.xl} 32px · {spacing.xxl} 48px · {spacing.section} 96px.
• Section padding: {spacing.section} (96px) for every major editorial band.
• Card internal padding: {spacing.xl} (32px) for feature cards and product-UI mockups.

Grid & Container

• Max content width: ~1200px centered. Hero photography full-bleed.
• Editorial body: Single 12-column grid.
• Feature card grids: 2-up at desktop for hero splits, 3-up for benefit grids.
• Footer: 6-column link list at desktop.

Whitespace Philosophy

Generous editorial pacing — closer to Bloomberg or the Financial Times than to a trading dashboard. 96px between bands; cards inside bands sit 24px apart. Density lives behind login walls, not on marketing.

Elevation & Depth

Decorative Depth

• Layered product-UI cards inside dark heroes is the most distinctive decorative pattern — a {component.product-ui-card-dark} floats above a darker base canvas, often with a second smaller card overlapping at an angle.
• Geometric brand illustrations carry illustrative depth where shadows would otherwise.

Shapes

Border Radius Scale

Pill for interactive, card-radius (24px) for containers, full circle for icons. Sharp corners absent.

Do's and Don'ts

Do

• Reserve {colors.primary} (Coinbase Blue) for primary CTAs, wordmark, brand-glyph illustrations, inline accent links.
• Set every CTA as {rounded.pill} (100px); every asset glyph as {rounded.full}.
• Keep CoinbaseDisplay headlines at weight 400.
• Use the dark/light band rotation as page rhythm.
• Render every numerical value in CoinbaseMono via {typography.number-display}.
• Pair every dark hero with a layered product-UI mockup card stack.

Don't

• Don't introduce a secondary brand color. Coinbase Blue is the only action color; trading green/red are semantic-only.
• Don't bold display copy — display sits at weight 400; bolding shifts the brand voice.
• Don't add drop shadow tiers — system has one shadow tier.
• Don't use sharp {rounded.none} (0px) on CTAs.
• Don't mix CoinbaseDisplay and CoinbaseSans inside the same headline.
• Don't use trading green/red as a button background.
• Don't extract a CTA color from a third-party widget (cookie consent, OneTrust). The brand's CTA color is what appears on actual product CTAs, not on injected modals.

Responsive Behavior

Breakpoints

Touch Targets

• Primary CTA pill at 44px height — at WCAG AAA.
• Larger hero pill ({component.button-pill-cta}) at 56px — well above AAA.
• Asset icon circles at 32px — borderline; padded 8px row creates effective 48px tap zone.
• Search pill at 44px height — at AAA.

Collapsing Strategy

• Top nav switches to hamburger sheet below 768px. Sign Up CTA stays visible.
• Hero h1 steps down: 80 → 64 → 52 → 44 → 36px on smallest screens.
• Layered product-UI mockup cards collapse from 2-3 stacked into a single card on mobile.
• Pricing tier rows: 3-up → 2-up → 1-up.
• Asset rows on mobile stack vertically: ticker line on top, price + change line beneath.

Iteration Guide

1. Focus on a single component at a time. Reference YAML keys directly.
2. New CTAs default to {rounded.pill} (100px); new icon plates default to {rounded.full}. Cards use {rounded.xl}.
3. Variants live as separate entries inside the components: block.
4. Use {token.refs} everywhere — never inline hex.
5. Hover state never documented. Only Default and Active/Pressed.
6. CoinbaseDisplay 400 for display, CoinbaseSans 400/600/700 for body. CoinbaseMono on every number.
7. Coinbase Blue stays scarce — one or two blue moments per band.

Known Gaps

• CoinbaseDisplay, CoinbaseSans, CoinbaseMono are licensed; Inter and JetBrains Mono are documented substitutes.
• In-product trading surfaces (order book, charts, order forms) are behind login walls — this document covers marketing only.
• Animation timings out of scope.
• Form validation states beyond focus not visible on captured surfaces.
• Accent yellow appears only inside Bitcoin asset glyph illustrations; documented as illustrative-only.
