Tokens

Signal Mobile's decoded design system: background #000000, text #FFFFFF, accent #2267F5, link #2267F5, primary #2267F5; type scale h1 34px / h2 22px / body 17px; 6px spacing base; 12px base radius. The single interactive/action color is #2267F5 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#000000`
surface	`#0F0F0F`
border	`#262626`
text	`#FFFFFF`
text_muted	`#9E9E9E`
primary	`#2267F5`
accent	`#2267F5`
link	`#2267F5`
button_bg	`#2267F5`
button_text	`#000000`

Using these colors

Action color #2267F5 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #2267F5 — one role, not several (the action color).
accent #2267F5 — 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.

# Signal Mobile — Design System

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

Signal 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 | `#000000` |
| surface | `#0F0F0F` |
| border | `#262626` |
| text | `#FFFFFF` |
| text_muted | `#9E9E9E` |
| primary | `#2267F5` |
| accent | `#2267F5` |
| link | `#2267F5` |
| button_bg | `#2267F5` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#2267F5` — 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 `#2267F5` — one role, not several (your action color).
- **accent** `#2267F5` — 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): `#9DBBF8` 49.4% · `#FFFFFF` 22.9% · `#19191B` 16.9% · `#70718A` 6.6%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 60px / 800 · lh 64px |
| h2 | 40px / 800 · lh 44px |
| h3 | 28px / 800 · lh 32px |
| body | 20px / 400 · lh 28px |
| small | 16px / 400 · lh 22px |

- Weight ladder: 400 · 600 · 800 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 6px (inferred from the measured scale)
- measured scale: 8px, 9px, 12px, 16px, 19px, 20px, 24px, 30px, 48px, 96px — snap all gaps/padding to these
- section rhythm: 48px top/bottom padding per section (measured)

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

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#2C6BED` | none | 8px | 0px 20px 0px 20px | 600 20px | rgba(51, 51, 51, 0.05) 0px 1.25px 2.5px 0px, rgba(51, 51, 51, 0.05) 0px 2.5px 5px 0px |
| secondary | `rgba(255, 255, 255, 0)` / `#1B1B1B` | none | — | 8px 12px 8px 12px | 400 16px | none |

**States (measured, not guessed)**

- primary hover: color `#1851B4`
- primary focus: box-shadow `rgba(66, 88, 255, 0.25) 0px 0px 0px 3.75px`
- secondary hover: background `rgba(0, 0, 0, 0)` · color `#2C6BED`
- transition: `background-color 0.294s ease`

## Shadows (elevation)
- subtle: `rgba(51, 51, 51, 0.05) 0px 1.25px 2.5px 0px, rgba(51, 51, 51, 0.05) 0px 2.5px 5px 0px`
- card: `rgba(0, 0, 0, 0.12) 0px 4px 12px 0px, rgba(0, 0, 0, 0.08) 0px 0px 2px 0px`

## Motion
- durations: 294ms (dominant)
- easings: `ease` (dominant)
- animated properties: color, background-color, border-color, box-shadow

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

## 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.
