Tokens

Gemini Mobile's decoded design system: background #000000, text #FFFFFF, accent #1F3DA0, link #1F3DA0, primary #1F3DA0; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #1F3DA0 — 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	`#1F3DA0`
accent	`#1F3DA0`
link	`#1F3DA0`
button_bg	`#1F3DA0`
button_text	`#000000`

Using these colors

Action color #1F3DA0 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #1F3DA0 — one role, not several (the action color).
accent #1F3DA0 — 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.

# Gemini Mobile — Design System

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

Gemini 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 | `#1F3DA0` |
| accent | `#1F3DA0` |
| link | `#1F3DA0` |
| button_bg | `#1F3DA0` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#1F3DA0` — 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 `#1F3DA0` — one role, not several (your action color).
- **accent** `#1F3DA0` — 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): `#ABABAB` 74.4% · `#FFFFFF` 23.2% · `#BDBDBD` 2.4%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 36px / 320 · lh 44px |
| h2 | 20px / 470 · lh 24px |
| body | 15px / 400 · lh 20px |
| small | 14px / 500 |

- Weight ladder: 320 · 370 · 400 · 500 · 540 — use these exact measured weights, not the 400/600 defaults.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 12px, 15px, 16px, 20px, 24px, 40px, 52px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 12px
- card: 50px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#0B57D0` / `#FFFFFF` | none | 9999px | 0px 24px 0px 24px | 500 14px | none |
| secondary | `#FFFFFF` / `#444746` | 1px solid rgb(196, 199, 197) | 9999px | 0px 12px 0px 12px | 400 13.3333px | none |

**States (measured, not guessed)**

- transition: `box-shadow 0.28s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.16) 0px 2px 8px -2px`
- overlay: `rgba(0, 0, 0, 0.04) 0px 0px 20px 0px`

## Motion
- durations: 500ms (dominant) · 250ms · 280ms
- easings: `cubic-bezier(0.2, 0, 0, 1)` (dominant) · `ease`
- animated properties: opacity, box-shadow, transform, -webkit-transform

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 |
|-------|-------|
| `--mat-focus-indicator-border-width` | `1px` |

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

## Layout (measured)
- container max 640px

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 126 | 292 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `chat-window.center-input-layout` @0ms → `div.mic-button-container` @824ms → `h1.gds-display-m` @946ms → `div.nl-blob` @1577ms → `div.nl-blob` @1577ms → `div.nl-blob` @1577ms
- `chat-window.center-input-layout` — opacity 0→1 · transform translate(-50%, -45%) scale(0)→translate(-50%, -45%) scale(1) — 1000ms cubic-bezier(0.2, 0, 0, 1)
- `div.nl-blob` — scale 1→1 — 9100ms ease-in-out (delay -5500ms) · loops
- `div.nl-blob` — translate 140px -30px→-130px -10px — 4300ms cubic-bezier(0.45, 0, 0.55, 1) (delay -1200ms) · loops
- `div.nl-blob` — transform rotate(58deg)→rotate(58deg) — 11700ms ease-in-out · loops
- `div.nl-blob` — scale 0.87→0.87 — 9490ms ease-in-out · loops
- `div.nl-blob` — translate -200px→-200px — 6000ms cubic-bezier(0.76, 0, 0.24, 1) · loops
- scroll reveal: 2 elements rest at translateY(-24px) (2 revealed during the drive).
- 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)
- link: #444746 · underline
- disabled: bg rgba(0, 0, 0, 0) · text color(srgb 0.121569 0.121569 0.121569 / 0.38)

## Themes (both measured)
- dark counterpart: bg `#0F0F0F` · text `#E3E3E3`

## Responsive (measured)
- breakpoints: 480px · 600px · 768px · 960px · 1280px
- mobile (390px): hero 32px · body 16px · 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.
