Decoded design system

TikTok Mobile's decoded design system: background #000000, text #FFFFFF, accent #A24500, link #F0F0F0, primary #A24500; type scale h1 17px / h2 16px / body 12px; 4px spacing base; 12px base radius. The single interactive/action color is #FE2C55 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FE2C55 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #A24500 — one role, not several (the action color).
• accent #A24500 — accent for emphasis — keep it rare on the page.
• link #F0F0F0 — reads as a neutral UI color, not a link accent — verify against the reference (action = #FE2C55).

# TikTok Mobile — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#000000` |
| surface | `#0F0F0F` |
| border | `#262626` |
| text | `#FFFFFF` |
| text_muted | `#9E9E9E` |
| primary | `#A24500` |
| accent | `#A24500` |
| link | `#F0F0F0` |
| button_bg | `#FE2C55` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#FE2C55` — 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` are all `#A24500` — one role, not several.
- **accent** `#A24500` — accent for emphasis — keep it rare on the page.
- **link** `#F0F0F0` — reads as a neutral UI color, not a link accent — verify against the reference (action = #FE2C55).
- **Page coverage** (full-page screenshot pixels): `#000000` 51.8% · `#10A2C5` 19.3% · `#4D4141` 16.3% · `#292C2B` 7.2%

## Typography

- Heading: **TikTokFont** _(free fallback: Newsreader)_
- Body: **TikTokFont** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 17px / 500 · lh 22px |
| h2 | 16px / 500 · lh 21px · tracking 0.15px |
| h3 | 15px / 700 · lh 22px |
| body | 12px / 700 · lh 16px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 12px, 15px, 16px, 48px, 64px, 80px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 6px
- card: 6px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FE2C55` / `#FFFFFF` | none | 6px | 1px 16px 1px 16px | 500 16px / 0.15px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#F6F6F6` | none | 6px | 0px 0px 0px 0px | 500 16px / 0.15px | none |

**States (measured, not guessed)**

- primary hover: background `#EA284E`
- primary focus: outline `2px solid rgb(250, 250, 250)`
- secondary hover: background `rgba(255, 255, 255, 0.13)`

## Shadows (elevation)
- subtle: `rgba(255, 255, 255, 0.12) 0px 0px 1px 1px`
- card: `rgba(0, 0, 0, 0.07) 0px 2px 10px 0px`

## Motion
- durations: 300ms (dominant) · 250ms · 400ms
- easings: `ease` (dominant) · `cubic-bezier(0.25, 0, 0.25, 1)`
- animated properties: color, width, height, opacity

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

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

## Layout (measured)

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

## Motion choreography (measured)
Load order: `circle.css-ekyh5y-5e6d46e3--Cir` @0ms → `circle.css-qo7tz1-5e6d46e3--Cir` @0ms → `circle.css-1qqiap1-5e6d46e3--Ci` @0ms → `circle.css-3zkl3g-5e6d46e3--Cir` @1ms → `circle.css-12k1pbc-5e6d46e3--Ci` @1ms

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

## Components (measured)
- link: #F0F0F0 · no underline
- disabled: bg rgba(255, 255, 255, 0.13) · text #F6F6F6

## Responsive (measured)
- mobile (390px): 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.
