Decoded design system

Coinbase's decoded design system: background #FFFFFF, text #000000, accent #0052FF, link #FFFFFF, primary #0667D0; type scale h1 80px / h2 64px / body 16px; 8px spacing base; 16px base radius. The single interactive/action color is #0052FF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0052FF — the single interactive color; only on things you click or must notice, never large fills.
• accent, button_bg are all #0052FF — one role, not several (the action color).
• accent #0052FF — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
• primary #0667D0 — a brand color — but the call-to-action uses #0052FF, not this.
• link #FFFFFF — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
• secondary #578BFA — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Coinbase — Design System

> light, professional, medium, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#0667D0` |
| accent | `#0052FF` |
| link | `#FFFFFF` |
| secondary | `#578BFA` |
| button_bg | `#0052FF` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#0052FF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#0052FF` — one role, not several (your action color).
- **accent** `#0052FF` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#0667D0` — a brand color — but the call-to-action uses #0052FF, not this.
- **link** `#FFFFFF` — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#578BFA` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 62.7% · `#EEF0F3` 30.4% · `#2B3A5A` 4% · `#C9CCD3` 2.9%

## Typography

- Heading: **Coinbase Display** _(free fallback: Newsreader)_
- Body: **Coinbase Sans** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 80px / 400 · lh 80px |
| h2 | 64px / 400 · lh 64px |
| h3 | 52px / 400 · lh 52px |
| body | 16px / 400 · lh 24px |
| small | 14px / 400 · lh 21px |

- Weight ladder: 400 · 600 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Coinbase Display may be proprietary — safe free fallback: Newsreader (Google Fonts). Coinbase Sans may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 12px, 16px, 24px, 30px, 32px, 48px — snap all gaps/padding to these

## Radius
- base: 16px
- button: 56px
- card: 16px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0052FF` / `#FFFFFF` | none | 56px | 0px 24px 0px 24px | 600 16px | none |
| secondary | `#0A0B0D` / `#FFFFFF` | 1px solid rgb(10, 11, 13) | 40px | 8px 16px 8px 16px | 600 16px / 0.16px | none |

**States (measured, not guessed)**

- primary hover: background `rgba(0, 72, 224, 0.88)`
- primary focus: outline `2px solid rgb(0, 82, 255)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 0px 18px 0px`

## Motion
- durations: 300ms (dominant) · 200ms
- easings: `ease-in-out` (dominant)
- animated properties: width, transform, background-color, opacity

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Their own tokens (verbatim from :root)

| Token | Value |
|-------|-------|
| `--full-view-height` | `900px` |
| `--full-view-width` | `1440px` |

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1600px · common grid: 2-col
- nav: 0px

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 110 | 803 | 2 | 48 | 0/0 | — |
| 442 | 572 | 2 | — | 0/0 | 57/43 |
| 913 | 702 | — | — | 0/0 | — |
| 1615 | 800 | — | — | 0/0 | — |
| 2415 | 596 | — | — | 0/0 | — |
| 3011 | 624 | — | — | 0/0 | — |
| 3635 | 705 | 2 | 16 | 0/0 | — |
| 4339 | 1136 | 2 | 16 | 0/0 | — |

## Motion choreography (measured)
Load order: `a.GlobalNavLink__StyledLin` @0ms
- overlay dialog (auto-opened): panel rgba(0, 0, 0, 0) · r 0px

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #5B616E · underline

## Responsive (measured)
- breakpoints: 400px · 426px · 550px · 600px · 768px · 896px
- mobile (390px): hero 52px · body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
