Tokens

Gmail Mobile's decoded design system: background #FFFFFF, text #000000, accent #EB8D87, link #EB8D87, primary #EB8D87; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #EB8D87 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #EB8D87 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #EB8D87 — one role, not several (the action color).
• accent #EB8D87 — 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.

# Gmail Mobile — Design System

> light, consumer, high — deep decode (measured live)

Gmail Mobile — palette measured from official store listing screenshots (colors only; no font claims). Type scale shown is the platform HIG default.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#EB8D87` |
| accent | `#EB8D87` |
| link | `#EB8D87` |
| button_bg | `#EB8D87` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#EB8D87` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `link`, `button_bg` are all `#EB8D87` — one role, not several (your action color).
- **accent** `#EB8D87` — 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.
- **Page coverage** (full-page screenshot pixels): `#F0F4F9` 98.8% · `#B5C1D4` 1.2%

## Typography

- h1: 34px
- h2: 22px
- body: 17px

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 3px, 8px, 9px, 12px, 14px, 16px, 24px, 36px, 48px, 108px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0B57D0` / `#FFFFFF` | none | 20px | 0px 24px 0px 24px | 500 14px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#0B57D0` | none | 20px | 0px 16px 0px 16px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: box-shadow `rgba(60, 64, 67, 0.3) 0px 1px 2px 0px, rgba(60, 64, 67, 0.15) 0px 1px 3px 1px`
- transition: `border 0.28s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 280ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)
- animated properties: opacity, transform, border, box-shadow

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)

| `--gm3-sys-color-error-container` | `rgb(249 222 220 / 1)` |
| `--gm3-sys-color-inverse-on-surface` | `rgb(242 242 242 / 1)` |

| `--gm3-sys-color-on-secondary` | `rgb(255 255 255 / 1)` |

_…and 24 more measured on the page._

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

## Layout (measured)
- container max 1408px

## Motion choreography (measured)
Load order: `div.AxOyFc` @0ms → `div.OabDMe` @0ms
- scroll reveal: 1 elements rest at opacity 0, animate in over 0.1s cubic-bezier(0.2, 0, 0, 1) (0 revealed during the drive).

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

## Components (measured)
- input: h 28px · r 4px · bg rgba(0, 0, 0, 0) · placeholder #1F1F1F
- link: #0B57D0 · no underline

## Themes (both measured)
- dark counterpart: bg `#0E0E0E` · text `#E3E3E3`

## Responsive (measured)
- breakpoints: 481px · 592px · 600px · 672px · 720px · 960px
- mobile (390px): hero 32px · body 14px · 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.
