Excalidraw's brand is a handwriting: Virgil, the hand-drawn face of every sketch it exports, with Assistant at UI sizes running the chrome. The site is the whiteboard itself — wobbly rectangles, marker arrows, collaborative cursors — proof that a design tool can brand itself entirely through the artifacts its users make.

# Excalidraw — Design System

> light, modern, medium, custom

Excalidraw's brand is a handwriting: Virgil, the hand-drawn face of every sketch it exports, with Assistant at UI sizes running the chrome. The site is the whiteboard itself — wobbly rectangles, marker arrows, collaborative cursors — proof that a design tool can brand itself entirely through the artifacts its users make.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#6965DB` |
| accent | `#FA5252` |
| link | `#FA5252` |
| secondary | `#228BE6` |
| button_bg | `#6965DB` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#6965DB` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `button_bg` are all `#6965DB` — one role, not several (your action color).
- `accent`, `link` are all `#FA5252` — one role, not several.
- **accent** `#FA5252` — accent for emphasis — keep it rare on the page.
- **secondary** `#228BE6` — 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.

## Typography

- Heading: **Assistant** _(free fallback: Newsreader)_
- Body: **Arial**
- h1: 32px
- h2: 24px
- body: 16px

> **Fonts —** Assistant may be proprietary — safe free fallback: Newsreader (Google Fonts). Arial — system font, no web load needed.

## Spacing
- base unit: 4px
- scale: 2px, 4px, 6px, 8px, 12px, 16px, 24px, 32px

## Radius
- base: 8px
- button: 8px

## Primary button
- bg `#6965DB` · text `#FFFFFF` · radius 8px

## 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.
