Decoded design system

Glossier's decoded design system: background #FFFFFF, text #000000, accent #C8102E, link #C8102E, primary #0600FF; type scale h1 32px / h2 20px / body 14px; 4px spacing base; 0px base radius. The single interactive/action color is #F7F7F7 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #F7F7F7 — the single interactive color; only on things you click or must notice, never large fills.
• accent, link are all #C8102E — one role, not several (the action color).
• accent #C8102E — accent for emphasis — keep it rare on the page.
• primary #0600FF — a brand color — but the call-to-action uses #F7F7F7, not this.
• secondary #E3785E — 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.

# Glossier — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#0600FF` |
| accent | `#C8102E` |
| link | `#C8102E` |
| secondary | `#E3785E` |
| button_bg | `#F7F7F7` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#F7F7F7` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link` are all `#C8102E` — one role, not several.
- **accent** `#C8102E` — accent for emphasis — keep it rare on the page.
- **primary** `#0600FF` — a brand color — but the call-to-action uses #F7F7F7, not this.
- **secondary** `#E3785E` — 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): `#616365` 39.4% · `#FFFFFF` 17.9% · `#070607` 12.7% · `#16191D` 12.1%

## Typography

- Heading: **Gill Sans** _(free fallback: Newsreader)_
- Body: **Apercu** _(free fallback: Newsreader)_
- Mono: **Apercu Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 32px / 400 |
| h2 | 20px / 400 · lh 28px |
| body | 14px / 400 · lh 20px |
| small | 13px / 400 · lh 18px · tracking 0.66px |
| eyebrow | 12px / 400 · tracking 0.48px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 5px, 6px, 7px, 8px, 10px, 12px, 14px, 15px, 16px — snap all gaps/padding to these

## Radius
- base: 0px
- button: 0px
- card: 50px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#F7F7F7` / `#000000` | 1px solid rgb(0, 0, 0) | 0px | 0px 0px 0px 0px | 400 14px | none |
| secondary | `#FFFFFF` / `#000000` | 1px solid rgb(0, 0, 0) | 0px | 0px 0px 0px 0px | 400 14px | none |

**States (measured, not guessed)**

- primary hover: background `#E2E2E2`
- primary focus: outline `3px auto rgb(0, 0, 0)`
- secondary hover: background `#E2E2E2`

## Motion
- durations: 400ms (dominant) · 1500ms · 500ms
- easings: `ease-in-out` (dominant) · `linear`
- animated properties: font-size, opacity, padding, margin

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 |
|-------|-------|
| `--kl-reviews-color-light-gray` | `#e9e9eb` |
| `--rc-color` | `#040404` |
| `--rc-active-bg` | `#efefef` |
| `--rc-active-color` | `#000000` |
| `--header-height` | `2.5rem` |
| `--promo-bar-height` | `31.984375px` |

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

## Layout (measured)
- container max 730px
- nav: 40px fixed · border-bottom 1px solid rgba(0, 0, 0, 0.06) · bg #FFFFFF

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 96 | 785 | — | — | 0/0 | — |
| 881 | 429 | — | — | 0/0 | — |
| 1541 | 741 | — | — | 0/0 | — |
| 2282 | 570 | — | — | 0/0 | — |
| 2932 | 516 | — | — | 0/0 | — |
| 3544 | 684 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `label.swatch`×80 @0ms → `button.modal__close`×5 @395ms → `div.promo-bar__carousel-slid`×5 @585ms → `div.promo-bar__carousel-slid`×117 @585ms → `header.header` @585ms → `nav.nav` @585ms
- `div.promo-bar__carousel-slid` — color rgba(255, 255, 255, 0.996)→rgba(0, 0, 0, 0) — 898ms ease-in-out (delay 900ms)
- scroll reveal: 21 elements rest at opacity 0, animate in over 0.5s ease-in-out (2 revealed during the drive).
- overlay dialog (auto-opened): panel rgba(0, 0, 0, 0.6) · r 0px
  - enter: opacity from 0 · 350ms linear
  - exit: opacity from 1 · 350ms linear | transform+opacity from translate3d(0px, 10%, 0px),0 · 350ms linear

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

## Components (measured)
- input: h 46px · r 0px · border 1px solid rgb(232, 232, 232) · bg #FFFFFF · placeholder #666666
  - focus ring: `2px auto rgb(255, 255, 255)` — this exact construction, don't invent your own
- link: rgba(0, 0, 0, 0) · underline — hover #FFFFFF

## Responsive (measured)
- breakpoints: 425px · 550px · 600px · 640px · 700px · 768px
- mobile (390px): 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.
