Tokens

Uber Mobile's decoded design system: background #FFFFFF, text #000000, accent #236BF1, link #236BF1, primary #236BF1; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #236BF1 — 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	`#236BF1`
accent	`#236BF1`
link	`#236BF1`
button_bg	`#236BF1`
button_text	`#FFFFFF`

Using these colors

Action color #236BF1 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #236BF1 — one role, not several (the action color).
accent #236BF1 — 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.

# Uber Mobile — Design System

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

Uber 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 | `#236BF1` |
| accent | `#236BF1` |
| link | `#236BF1` |
| button_bg | `#236BF1` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#236BF1` — 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 `#236BF1` — one role, not several (your action color).
- **accent** `#236BF1` — 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): `#FFFFFF` 71.2% · `#150302` 10.7% · `#7D2E20` 6.4% · `#928083` 5.4%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 52px / 700 · lh 64px |
| h2 | 36px / 700 · lh 44px |
| h3 | 28px / 700 · lh 36px |
| body | 16px / 400 · lh 24px |
| small | 14px / 400 · lh 20px |

- Weight ladder: 400 · 500 · 700 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 12px, 14px, 16px, 24px, 25px, 32px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 8px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#000000` | none | 9999px | 10px 12px 10px 12px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: box-shadow `rgba(255, 255, 255, 0.1) 999px 999px 0px 0px inset` · background `#E2E2E2`
- primary focus: box-shadow `rgb(255, 255, 255) 0px 0px 0px 2px inset, rgb(39, 110, 241) 0px 0px 0px 2px` · background `#E2E2E2`
- transition: `background 0.2s cubic-bezier(0, 0, 1, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.16) 0px 4px 16px 0px`

## Motion
- durations: 200ms (dominant) · 500ms · 300ms
- easings: `cubic-bezier(0.22, 1, 0.36, 1)` (dominant) · `cubic-bezier(0, 0, 1, 1)`
- animated properties: backgroundSize, background, border, 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 1280px
- nav: 64px sticky · bg #000000

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 64 | 587 | — | — | 0/0 | — |
| 651 | 252 | — | — | 0/0 | — |
| 903 | 500 | — | — | 0/0 | — |
| 1403 | 534 | — | — | 0/0 | — |
| 1937 | 500 | — | — | 0/0 | — |
| 2437 | 686 | — | — | 0/0 | — |
| 3123 | 686 | — | — | 0/0 | — |
| 3809 | 500 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.css-kvneza` @0ms → `div.css-copPLX` @1ms → `div.css-hxrHKS`×3 @1ms → `div.css-fWlmLG`×3 @1ms → `div.css-eGUOWt`×3 @1ms → `div.css-lcusNn`×3 @1ms
- 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)
- input: h 44px · r 0px · bg rgba(0, 0, 0, 0) · placeholder #5E5E5E
- card ×3: pad 0px 0px 0px 0px · r 8px · bg #F3F3F3
  - hover: font-weight `400` · letter-spacing `normal`
- link: #FFFFFF · no underline

## Responsive (measured)
- breakpoints: 320px · 600px · 768px · 1120px · 1136px
- mobile (390px): hero 36px · body 16px · nav: hamburger

## 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.
