Decoded design system

Bellroy's decoded design system: background #BFBFBF, text #000000, accent #CD4C20, link #666666, primary #CD4C20; type scale h1 70px / h2 32px / body 13px; 4px spacing base; 0px base radius. The single interactive/action color is #CD4C20 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #CD4C20 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #CD4C20 — one role, not several (the action color).
• accent #CD4C20 — 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.
• link #666666 — reads as a neutral UI color, not a link accent — verify against the reference (action = #CD4C20).
• secondary #B85021 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Bellroy — Design System

> light, modern, medium, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#BFBFBF` |
| surface | `#B3B3B3` |
| border | `#A2A2A2` |
| text | `#000000` |
| text_muted | `#484848` |
| primary | `#CD4C20` |
| accent | `#CD4C20` |
| link | `#666666` |
| secondary | `#B85021` |
| button_bg | `#CD4C20` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#CD4C20` — 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`, `button_bg` are all `#CD4C20` — one role, not several (your action color).
- **accent** `#CD4C20` — 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.
- **link** `#666666` — reads as a neutral UI color, not a link accent — verify against the reference (action = #CD4C20).
- **secondary** `#B85021` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#A5A5A5` 30.3% · `#FFFFFF` 23% · `#343035` 15.7% · `#504441` 11.5%

## Typography

- Heading: **GTUltra** _(free fallback: Newsreader)_
- Body: **Lato**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 70px / 900 · lh 77px |
| h2 | 32px / 400 · lh 42px |
| h3 | 25px / 400 · lh 31px |
| body | 13px / 400 · lh 21px · tracking 0.33px |
| small | 12px / 700 · lh 18px · tracking 1px |
| eyebrow | 13px / 800 · tracking 1.95px |

- Weight ladder: 400 · 700 · 800 · 900 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** GTUltra may be proprietary — safe free fallback: Newsreader (Google Fonts). Lato — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 3px, 4px, 5px, 7px, 11px, 14px, 18px, 21px, 28px — snap all gaps/padding to these

## Radius
- base: 0px
- button: 3.5px
- card: 5px
- pill: 9999px
- sharp: 3px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#CD4C20` / `#FFFFFF` | none | 3.5px | 7px 14px 7px 14px | 800 13px / 1.95px | rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.3) 0px 27px 15px -30px, rgba(0, 0, 0, 0.5) 0px 11px 9px -10px |
| secondary | `#FFFFFF` / `#CD4C20` | none | 0px | — | — | none |

**States (measured, not guessed)**

- primary hover: box-shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.3) 0px 20px 10px -35px, rgba(0, 0, 0, 0.5) 0px 4px 9px -5px` · background `#B85021`
- primary focus: outline `2px solid rgba(0, 0, 0, 0)`
- transition: `color 0.2s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.3) 0px 27px 15px -30px, rgba(0, 0, 0, 0.5) 0px 11px 9px -10px`
- card: `rgba(0, 0, 0, 0.5) 0px 17px 9px -15px`
- button: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.3) 0px 27px 15px -30px, rgba(0, 0, 0, 0.5) 0px 11px 9px -10px`

## Motion
- durations: 150ms (dominant) · 200ms · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- animated properties: transform, background-color, opacity, color

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

- overlay dialog (auto-opened): panel #FFFFFF · r 0px

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

## Components (measured)
- input: h 34px · r 0px · bg #FFFFFF · placeholder #B0B0B0
- link: #CD4C20 · underline

## Responsive (measured)

- mobile (390px): hero 32px · 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.
