# Lucide Design System

## Overview

Lucide describes itself as: “Beautiful & consistent icon toolkit made by the community.” The interface is light, built on **White (#FFFFFF)** with **Cool Graphite (#3C3C43)** text, and **Light Red (#F67373)** as the main accent.

Type is set in **Inter**, with **ui-monospace** for code. Headlines run large; body text is 16px. Depth comes from soft drop shadows. Corners are mostly 8px.

Measured from [lucide.dev](https://lucide.dev/) on November 4, 2026 at 1440×900 and 390×844 from 315 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 12 roles.

- **White (#FFFFFF):** Page background, seen 70 times. Token `background`, CSS `--vp-local-nav-bg-color`.
- **Cool Graphite (#3C3C43):** Primary text and headings, seen 38 times. Token `on-surface`, CSS `--vp-code-tab-hover-text-color`.
- **Slate (#67676C):** Secondary text, seen 21 times. Token `on-surface-variant`, CSS `--vp-code-block-color`.
- **Snow (#F6F6F7):** Raised areas one step from the page, seen 8 times. Token `surface-container-low`, CSS `--vp-code-block-bg`.
- **Mist (#EBEBEF):** Cards and panels, seen 3 times. Token `surface-container`, CSS `--vp-c-default-3`.
- **Blue 14% (#8E96AA24):** Translucent fill for cards and controls, seen 2 times. Token `overlay`, CSS `--vp-badge-info-bg`.
- **Mist (#E2E2E3):** Borders and dividers, seen 9 times. Token `outline`, CSS `--vp-code-block-divider-color`.
- **Silver (#C2C2C4):** Secondary dividers, seen 2 times. Token `outline-variant`.
- **Light Red (#F67373):** Primary buttons and calls to action, seen 7 times. Token `primary`, CSS `--vp-c-note-1`.
- **Cool Graphite (#3C3C43):** Text and icons on primary. Token `on-primary`.
- **Red (#F56565):** Secondary buttons, seen 3 times. Token `secondary`, CSS `--vp-c-tip-3`.
- **Red (#DC5A5A):** Accent (CSS variable). Token `tertiary`.

## Typography

**Inter** and **ui-monospace** (monospace) share the interface. Fallback stack: `Inter, ui-sans-serif, system-ui, sans-serif`.

- **headline-display:** Inter 21px at weight 500, line height 1.14. Page title (h1).
- **body-md:** Inter 16px at weight 400, line height 1.5. Body text.
- **label-lg:** Inter 16px at weight 600, line height 1.5. Large buttons and tabs.
- **label-md:** Inter 14px at weight 500, line height 1.71. Buttons, navigation and labels.
- **label-sm:** Inter 13px at weight 600, line height 1.54. Small labels and badges.
- **code:** ui-monospace 13px at weight 400, line height 1.85, tracking 0.077em. Code and technical values.

## Layout

Spacing follows a 4px grid: 92% of measured gaps and paddings are multiples of 4px.

- **Scale:** xs 2px, sm 8px, md 12px, lg 24px, xl 48px.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Page margin:** 32px on each side of full-width sections.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(0, 0, 0, 0.04) 0px 1px 2px 0px, rgba(0, 0, 0, 0.06) 0px 1px 2px 0px`
- `rgba(0, 0, 0, 0.1) 0px 12px 32px 0px, rgba(0, 0, 0, 0.08) 0px 2px 6px 0px`
- `rgba(0, 0, 0, 0.12) 0px 14px 44px 0px, rgba(0, 0, 0, 0.12) 0px 3px 9px 0px`

## Shapes

Most elements use 8px corners. Measured radii, most used first:

- **md (8px):** 68 elements.
- **lg (12px):** 32 elements.
- **xl (20px):** 20 elements.
- **sm (6px):** 8 elements.
- **full (9999px):** 8 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Icons”):** #F67373 fill, #3C3C43 text, 14px/500, 2px radius, padding 0px 12px.
- **button-outline (“Get Started”):** #EBEBEF fill, #3C3C43 text, 14px/600, 20px radius, padding 0px 20px.
- **button-outline-hover:** background #E4E4E9, text #3C3C43 on hover.
- **button-secondary (“View all icons”):** #F56565 fill, #FFFFFF text, 14px/600, 20px radius, padding 0px 20px.
- **button-ghost (“Resources”):** transparent fill, #3C3C43 text, 13.3333px/400, padding 0px 12px.
- **input-field:** transparent fill, #67676C text, 13.3333px/400, padding 0px.
- **card:** #F6F6F7 fill, #3C3C43 text, 16px/400, 12px radius, padding 24px, border 1px solid #E2E2E3.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #F6F6F7, #EBEBEF.
- Do keep text in 2 levels: #3C3C43, #67676C.
- Do reserve #F67373 for primary actions and key highlights.
- Do keep spacing on the 4px grid.
- Do use 8px corners on most elements; larger surfaces also use 12px, 20px and 6px.
- Don't introduce new font families beyond Inter and ui-monospace.
- Don't use #F67373 for large backgrounds or body text.
- Don't make interface transitions slower than 0.5s.

## Motion

Interface transitions are quick: 0.25s, 0.15s, 0.5s, 0.4s.

- **Easing:** `ease`, `ease-in`, `cubic-bezier(0.34, 1.56, 0.64, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
