Tokens

Twitch Mobile's decoded design system: background #0E0E10, text #FFFFFF, accent #008D8F, link #008D8F, primary #008D8F; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #008D8F — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #008D8F — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #008D8F — one role, not several (the action color).
• accent #008D8F — 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.

# Twitch Mobile — Design System

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

Twitch 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 | `#0E0E10` |
| surface | `#1C1C1E` |
| border | `#323233` |
| text | `#FFFFFF` |
| text_muted | `#A3A3A4` |
| primary | `#008D8F` |
| accent | `#008D8F` |
| link | `#008D8F` |
| button_bg | `#008D8F` |
| button_text | `#0E0E10` |

**Using these colors**

- **Action color** `#008D8F` — 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 `#008D8F` — one role, not several (your action color).
- **accent** `#008D8F` — 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): `#F7F7F8` 38.1% · `#451092` 21% · `#010001` 15.9% · `#6B387A` 11.6%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 18px / 500 · lh 20px · tracking -0.18px |
| body | 14px / 400 · lh 20px |
| small | 12px / 600 · lh 17px |

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 3px, 4px, 5px, 6px, 8px, 12px, 15px, 16px, 20px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 4px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#9147FF` / `#FFFFFF` | none | 9999px | 0px 0px 0px 0px | 600 14px | none |
| secondary | `#FFFFFF` / `#000000` | none | 9999px | 0px 0px 0px 0px | 600 14px | none |

**States (measured, not guessed)**

- primary hover: background `#772CE8`
- primary focus: box-shadow `rgb(119, 44, 232) 0px 0px 6px 0px` · background `#772CE8` · outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `rgba(255, 255, 255, 0.9)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.13) 0px 1px 2px 0px, rgba(0, 0, 0, 0.08) 0px 0px 2px 0px`
- card: `rgba(0, 0, 0, 0.22) 0px 6px 16px 0px, rgba(0, 0, 0, 0.08) 0px 0px 4px 0px`

## Motion
- durations: 100ms (dominant) · 200ms · 150ms
- easings: `ease` (dominant) · `ease-in`
- animated properties: transform, opacity, none, border

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 |
|-------|-------|

| `--color-brand-accent-cuddle` | `#fa1ed2` |
| `--color-brand-accent-dragon` | `#8205b3` |

| `--color-brand-accent-peach` | `#ea7179` |
| `--color-brand-accent-pylon` | `#00fafa` |

_…and 108 more measured on the page._

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

## Layout (measured)
- nav: 50px

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|

## Motion choreography (measured)
Load order: `div.shell-loader__spinner` @0ms → `div.shell-loader` @279ms → `div.ScLoadingSpinnerCircle-s`×2 @989ms → `span.ScPlaceholderFill-sc-wb1`×69 @1511ms → `div.ScLoadingSpinner-sc-bvza` @2351ms → `div.ScTransitionBase-sc-hx4q`×10 @2416ms
- `div.ScAnimation-sc-s60rmz-0` — transform scale3d(0.3, 0.3, 0.3)→scale3d(1.1, 1.1, 1.1) — 300ms cubic-bezier(0.215, 0.61, 0.355, 1)
- `span.ScPlaceholderFill-sc-wb1` ×16 — transform translateX(-100%)→translateX(0%) — 2000ms ease-out (delay 300ms)
- `div.ScLoadingSpinner-sc-bvza` — opacity 0→1 — 150ms ease (delay 300ms)
- `div.ScLoadingSpinnerCircle-s` — transform rotate(0deg)→rotate(360deg) — 1000ms · loops
- 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 36px · r 8px 0px 0px 8px · bg #FFFFFF · placeholder rgba(0, 0, 0, 0.7)
  - focus ring: `rgb(119, 44, 232) 0px 0px 0px 2px, rgb(119, 44, 232) 0px 0px 0px 2px inset` — this exact construction, don't invent your own
- link: #FFFFFF · underline — hover rgba(255, 255, 255, 0.8)
- disabled: bg rgba(173, 173, 184, 0.22) · text #0E0E10

## Responsive (measured)
- breakpoints: 768px · 1440px
- mobile (390px): hero 18px · 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.
