Luma — decoded design system

lumalabs.ai · light · modern · tailwind · deep decode — measured live

Luma's design system, decoded live by Mozaika: measured color roles, type scale, buttons with real hover/focus states, motion and the brand's own tokens.

Decoded design system

Luma's decoded design system: background #FFFFFF, text #000000, accent #000000, link #FFFFFF, primary #000000; type scale h1 52px / h2 48px / body 22px; 4px spacing base; 0px base radius. The single interactive/action color is #000000 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #000000 — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #000000 — one role, not several (the action color).
• accent #000000 — 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 #FFFFFF — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).

# Luma — Design System

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

## Colors

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

**Using these colors**

- **Action color** `#000000` — 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 `#000000` — one role, not several (your action color).
- **accent** `#000000` — 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** `#FFFFFF` — fails contrast on the background (~1.0:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 61.1% · `#000000` 21.7% · `#EDEDED` 4.9% · `#9F9F9F` 2.9%

## Typography

- Heading: **Graphik** _(free fallback: Inter)_
- Body: **Graphik** _(free fallback: Inter)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 52px / 500 · lh 62px · tracking -2.08px |
| h2 | 48px / 500 · lh 58px · tracking -1.92px |
| h3 | 32px / 700 · lh 38px · tracking -1.28px |
| body | 22px / 500 · lh 31px · tracking -0.66px |
| small | 18px / 400 · lh 25px · tracking -0.54px |

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

> **Fonts —** Graphik is proprietary — closest free match: Inter (Google). Load Inter; keep Graphik first so licensed users still get it.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 6px, 8px, 10px, 12px, 14px, 16px, 20px, 24px, 32px, 40px — snap all gaps/padding to these
- section rhythm: 160px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 6px
- card: 24px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `oklch(1 0 0)` / `#000000` | 1px solid oklch(0.922 0 0) | 6px | 0px 10px 0px 10px | 500 14px / -0.4px | rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px |
| secondary | `#FFFFFF` / `#000000` | 1px solid rgba(0, 0, 0, 0) | 3.35544e+07px | 0px 16px 0px 16px | 500 14px / -0.4px | none |

**States (measured, not guessed)**

- primary hover: background `oklch(0.97 0 0)` · color `oklch(0.145 0 0)`
- primary focus: border `1px solid oklch(0.708 0 0)`
- secondary hover: background `#000000` · color `#FFFFFF`
- transition: `all 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

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

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)

| `--background` | `oklch(100% 0 0)` |

## Motion choreography (measured)
Load order: `span.pointer-events-none` @0ms

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

## Components (measured)
- input: h 75.5625px · r 0px · bg rgba(0, 0, 0, 0) · placeholder #000000
- link: #FFFFFF · no underline

## Responsive (measured)
- breakpoints: 500px · 640px · 768px · 1024px · 1280px · 1536px
- 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.
