Tokens

WhatsApp Mobile's decoded design system: background #FFFFFF, text #000000, accent #005B5B, link #005B5B, primary #005B5B; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #005B5B — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#EFEFEF`
border	`#D8D8D8`
text	`#000000`
text_muted	`#606060`
primary	`#005B5B`
accent	`#005B5B`
link	`#005B5B`
button_bg	`#005B5B`
button_text	`#FFFFFF`

Using these colors

Action color #005B5B — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #005B5B — one role, not several (the action color).
accent #005B5B — 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.

# WhatsApp Mobile — Design System

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

WhatsApp 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 | `#005B5B` |
| accent | `#005B5B` |
| link | `#005B5B` |
| button_bg | `#005B5B` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#005B5B` — 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 `#005B5B` — one role, not several (your action color).
- **accent** `#005B5B` — 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): `#FCF5EB` 32.6% · `#272C27` 22% · `#4D483D` 16.3% · `#7A634F` 15.7%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 80px / 400 · lh 80px |
| h2 | 60px / 400 · lh 60px |
| h3 | 48px / 400 · lh 48px |
| body | 18px / 400 · lh 25px |
| small | 16px / 500 · lh 16px |

- Weight ladder: 400 · 500 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 13px, 16px, 20px, 24px, 28px, 32px, 40px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 50px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#25D366` / `#1C1E21` | 1px solid rgb(28, 30, 33) | 50px | 16px 28px 16px 28px | 400 16px | none |
| secondary | `#FFFFFF` / `#1C1E21` | 1px solid rgb(28, 30, 33) | 50px | 16px 28px 16px 28px | 400 16px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `color 0.33s linear`

## Motion
- durations: 330ms (dominant) · 1000ms · 500ms
- easings: `cubic-bezier(0.33, 0, 0, 1)` (dominant) · `linear`
- animated properties: color, border-color, background-color

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

## Layout (measured)
- container max 1080px · common grid: 2-col
- nav: 80px fixed · bg #FCF5EB

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 80 | 760 | — | — | 0/0 | — |
| 840 | 291 | — | — | 0/0 | — |
| 1131 | 304 | — | — | 0/0 | — |
| 1435 | 266 | — | — | 0/0 | — |
| 1701 | 802 | — | — | 0/0 | — |
| 2503 | 620 | 2 | 32 | 0/0 | 58/42 |
| 3123 | 846 | — | — | 0/0 | — |
| 3969 | 826 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div._wauiAnimationWrapper__c`×4 @0ms → `div._wauiAnimationWrapper__c`×4 @0ms
- scroll reveal: 10 elements rest at opacity 0, translateY(120px), animate in over 1s cubic-bezier(0.33, 0, 0, 1) (10 revealed during the drive).

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

## Components (measured)
- link: #1C1E21 · no underline

## Responsive (measured)
- breakpoints: 520px · 768px · 1024px · 1096px · 1176px · 1200px
- mobile (390px): hero 44px · body 12px · 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.
