Decoded design system

Instagram Mobile's decoded design system: background #FFFFFF, text #000000, accent #425BFF, link #425BFF, primary #425BFF; type scale h1 40px / h2 24px / body 14px; 4px spacing base; 12px base radius. The single interactive/action color is #F0F2F5 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F0F2F5 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link are all #425BFF — one role, not several (the action color).
• accent #425BFF — accent for emphasis — keep it rare on the page.

# Instagram Mobile — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#425BFF` |
| accent | `#425BFF` |
| link | `#425BFF` |
| button_bg | `#F0F2F5` |
| button_text | `#0C1014` |

**Using these colors**

- **Action color** `#F0F2F5` — 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` are all `#425BFF` — one role, not several.
- **accent** `#425BFF` — accent for emphasis — keep it rare on the page.
- **Page coverage** (full-page screenshot pixels): `#54575A` 69.6% · `#FFFFFF` 23.5% · `#333034` 6% · `#C8CACC` 0.9%

## Typography

- Heading: **Instagram Sans Regular** _(free fallback: Newsreader)_
- Body: **-apple-system**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 40px / 400 · lh 65px |
| h2 | 24px / 700 · lh 30px |
| h3 | 17px / 600 · lh 22px |
| body | 14px / 600 · lh 18px |
| small | 12px / 400 · lh 16px |

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

> **Fonts —** Instagram Sans Regular may be proprietary — safe free fallback: Newsreader (Google Fonts). -apple-system — system font, no web load needed.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 10px, 12px, 16px, 18px, 20px, 24px — snap all gaps/padding to these

## Radius
- base: 12px
- button: 8px
- card: 22px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F0F2F5` / `#0C1014` | none | 8px | 0px 16px 0px 16px | 600 14px | none |

**States (measured, not guessed)**

- primary hover: background `#E7EAEE`
- primary focus: box-shadow `rgb(255, 255, 255) 0px 0px 0px 2px, rgb(24, 119, 242) 0px 0px 0px 4px`

## Shadows (elevation)
- subtle: `rgb(255, 255, 255) 0px 0px 0px 2px, rgb(24, 119, 242) 0px 0px 0px 4px`

## Motion
- durations: 200ms (dominant) · 100ms · 150ms
- easings: `cubic-bezier(0.17, 0.17, 0, 1)` (dominant) · `cubic-bezier(0, 0, 1, 1)`
- animated properties: none

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 |
|-------|-------|
| `--fds-black` | `#000000` |
| `--fds-black-alpha-05` | `rgba(0, 0, 0, 0.05)` |
| `--fds-black-alpha-10` | `rgba(0, 0, 0, 0.1)` |
| `--fds-black-alpha-15` | `rgba(0, 0, 0, 0.15)` |
| `--fds-black-alpha-20` | `rgba(0, 0, 0, 0.2)` |
| `--fds-black-alpha-30` | `rgba(0, 0, 0, 0.3)` |
| `--fds-black-alpha-40` | `rgba(0, 0, 0, 0.4)` |
| `--fds-black-alpha-50` | `rgba(0, 0, 0, 0.5)` |
| `--fds-black-alpha-60` | `rgba(0, 0, 0, 0.6)` |
| `--fds-black-alpha-80` | `rgba(0, 0, 0, 0.8)` |
| `--fds-blue-05` | `#ECF3FF` |
| `--fds-blue-30` | `#AAC9FF` |

_…and 108 more measured on the page._

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

## Motion choreography (measured)
- 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 38px · r 0px · bg rgba(0, 0, 0, 0) · placeholder #111112
- disabled: bg rgba(0, 0, 0, 0) · text #000000

## Themes (both measured)
- dark counterpart: bg `#0C1014` · text `#F5F5F5`
- tokens that flip between modes:
  - `--fds-black`: `#000000` → `black`
  - `--fds-blue-05`: `#ECF3FF` → `black`
  - `--fds-blue-30`: `#AAC9FF` → `black`
  - `--fds-blue-40`: `#77A7FF` → `black`
  - `--fds-blue-60`: `#1877F2` → `black`
  - `--fds-blue-70`: `#2851A3` → `black`
  - `--fds-blue-80`: `#1D3C78` → `black`
  - `--fds-button-text`: `#444950` → `black`

## 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.
