Decoded design system

Bumble Mobile's decoded design system: background #FFFFFF, text #202020, accent #FFDB5B, link #FFFFFF, primary #FFDB5B; type scale h1 68px / h2 40px / body 20px; 4px spacing base; 12px base radius. The single interactive/action color is #202020 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #202020 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent are all #FFDB5B — one role, not several (the action color).
• accent #FFDB5B — accent for emphasis — keep it rare on the page.
• link #FFFFFF — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).

# Bumble Mobile — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F1F1F1` |
| border | `#DDDDDD` |
| text | `#202020` |
| text_muted | `#747474` |
| primary | `#FFDB5B` |
| accent | `#FFDB5B` |
| link | `#FFFFFF` |
| button_bg | `#202020` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#202020` — 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 `#FFDB5B` — one role, not several.
- **accent** `#FFDB5B` — accent for emphasis — keep it rare on the page.
- **link** `#FFFFFF` — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **Page coverage** (full-page screenshot pixels): `#FFDB5B` 33.8% · `#FFFFFF` 28.7% · `#4B3D36` 20% · `#E8ECE2` 8.5%

## Typography

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

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 68px / 600 · lh 70px · tracking 0.46px |
| h2 | 40px / 400 · lh 40px |
| h3 | 34px / 600 · lh 34px · tracking 0.4px |
| body | 20px / 400 · lh 25px · tracking 0.32px |
| small | 18px / 500 · lh 22px |
| eyebrow | 17px / 500 · tracking 0.3px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 8px, 10px, 12px, 14px, 15px, 16px, 20px, 22px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 40px top/bottom padding per section (measured)

## Radius
- base: 12px
- button: 16px
- card: 16px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#202020` / `#FFFFFF` | none | 16px | 14px 24px 14px 24px | 400 16px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#202020` | 1px solid rgba(0, 0, 0, 0) | — | 14px 22px 14px 22px | 500 17px / 0.3px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `opacity 0.2s ease`

## Shadows (elevation)
- subtle: `rgba(255, 255, 255, 0) 0px 0px 0px 0px`
- card: `rgba(32, 32, 32, 0.12) 0px 1px 8px 0px`

## Motion
- durations: 200ms (dominant) · 250ms · 400ms
- easings: `ease` (dominant) · `ease-in-out`
- animated properties: color, opacity, position, top

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

## Motion choreography (measured)
Load order: `div.animation-card__QRX4J`×3 @0ms → `div.animation-card__QRX4J` @1516ms → `div.animation-card__QRX4J` @1516ms → `div.animation-card__QRX4J` @1516ms → `div.animation-card__QRX4J` @1516ms

- `div.animation-card__QRX4J` ×3 — opacity 1→0 · transform scale(1) translate(0px)→scale(1.1) translate(-100px) — 400ms ease-in-out (delay 2500ms)
- `div.animation-card__QRX4J` ×3 — transform scale(0.75) translate(250px)→scale(1) translate(0px) — 400ms ease-in-out (delay 2500ms)
- `div.animation-card__QRX4J` ×3 — transform scale(0.5) translate(680px)→scale(0.75) translate(250px) — 400ms ease-in-out (delay 2500ms)
- `div.animation-card__QRX4J` ×3 — opacity 0→1 · transform scale(0.4) translate(900px)→scale(0.5) translate(680px) — 400ms ease-in-out (delay 2500ms)
- stagger: `div` ×6 — 1350ms apart

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

## Components (measured)
- card ×3: pad 0px 0px 0px 0px · r 16px · bg rgba(0, 0, 0, 0)
  - hover: font-weight `400` · letter-spacing `normal`

## Responsive (measured)
- breakpoints: 600px · 640px · 768px · 1024px · 1260px · 1360px
- mobile (390px): hero 32px · 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.
