Lovable — decoded design system

lovable.dev · light · modern · tailwind · deep decode — measured live

Lovable'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

Lovable's decoded design system: background #FAFAFA, text #030303, accent #1E1E1E, link #000000, primary #000000; type scale h1 60px / h2 48px / body 18px; 4px spacing base; 7px base radius. The single interactive/action color is #1E1E1E — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #1E1E1E — the single interactive color; only on things you click or must notice, never large fills.
• primary, link are all #000000 — one role, not several (the action color).
• accent, button_bg are all #1E1E1E — one role, not several (the action color).
• accent #1E1E1E — 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.

# Lovable — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#FAFAFA` |
| surface | `#EBEBEB` |
| border | `#D4D4D4` |
| text | `#030303` |
| text_muted | `#606060` |
| primary | `#000000` |
| accent | `#1E1E1E` |
| link | `#000000` |
| button_bg | `#1E1E1E` |
| button_text | `#FAFAFA` |

**Using these colors**

- **Action color** `#1E1E1E` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `link` are all `#000000` — one role, not several.
- `accent`, `button_bg` are all `#1E1E1E` — one role, not several (your action color).
- **accent** `#1E1E1E` — 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): `#FAFAF9` 29.8% · `#FE3C67` 24.6% · `#8D8BF0` 12.5% · `#FD759E` 12.2%

## Typography

- Heading: **Camera Plain Variable** _(free fallback: Newsreader)_
- Body: **Camera Plain Variable** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 60px / 480 · lh 60px |
| h2 | 48px / 600 · lh 53px · tracking -1.2px |
| h3 | 36px / 600 · lh 40px · tracking -0.9px |
| body | 18px / 400 · lh 25px |
| small | 16px / 400 · lh 24px |

- Weight ladder: 400 · 480 · 600 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Camera Plain Variable may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 10px, 12px, 16px, 20px, 24px, 56px — snap all gaps/padding to these
- section rhythm: 80px top/bottom padding per section (measured)

## Radius
- base: 7px
- button: 8px
- card: 12px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `lab(0 0 0 / 0.88)` / `lab(98.2716 0 0)` | none | 8px | 6px 10px 6px 10px | 400 14px | none |
| secondary | `#FAFAFA` / `#030303` | none | 0px | — | — | none |

**States (measured, not guessed)**

- primary focus: outline `2px solid lab(52.8042 18.2982 -74.3349 / 0.4)`

## Shadows (elevation)
- subtle: `oklch(0.2 0 0 / 0.12) 0px 2px 2px -1px, oklch(0.2 0 0 / 0.12) 0px 4px 4px -2px`
- card: `oklch(0 0 0 / 0.04) 0px 2px 2px -1px, oklch(0 0 0 / 0.02) 0px 4px 4px -2px`

## Motion
- durations: 150ms (dominant) · 200ms · 500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- animated properties: opacity, color, background-color, border-color

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

## 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.
