## CSS Variables

For web projects, use these CSS custom properties:

```css
/* Cosmonic Brand */
:root {
  --cosmonic-slate-purple: #685BC7;
  --cosmonic-light-gray: #768692;
  --cosmonic-yellow: #FFB600;
  --cosmonic-space-blue: #002E5D;
  --cosmonic-gunmetal: #253746;
  --cosmonic-gainsboro: #D9E1E2;
}

/* wasmCloud Brand */
:root {
  --wasmcloud-green-aqua: #00C389;
  --wasmcloud-light-gray: #768692;
  --wasmcloud-yellow: #FFB600;
  --wasmcloud-space-blue: #002E5D;
  --wasmcloud-gunmetal: #253746;
  --wasmcloud-gainsboro: #D9E1E2;
}
```

## Tailwind Configuration

For Tailwind CSS projects:

```javascript
// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      colors: {
        cosmonic: {
          purple: '#685BC7',
          gray: '#768692',
          yellow: '#FFB600',
          blue: '#002E5D',
          gunmetal: '#253746',
          gainsboro: '#D9E1E2',
        },
        wasmcloud: {
          aqua: '#00C389',
          gray: '#768692',
          yellow: '#FFB600',
          blue: '#002E5D',
          gunmetal: '#253746',
          gainsboro: '#D9E1E2',
        },
      },
      fontFamily: {
        cosmonic: ['Work Sans', 'Arial', 'sans-serif'],
        wasmcloud: ['Lexend', 'Arial', 'sans-serif'],
      },
    },
  },
};
```

## Excalidraw Diagrams

When creating diagrams, use the official wasmCloud & Wasm Excalidraw library which contains reusable components including wasmCloud cluster diagrams and architecture diagram elements.

**Library URL:** `https://raw.githubusercontent.com/excalidraw/excalidraw-libraries/ricochet-wasmcloud-and-wasm-1770917744834/libraries/ricochet/wasmcloud-and-wasm.excalidrawlib?raw=true`

**Add to Excalidraw:** [Install Library](https://excalidraw.com/?addLibrary=https%3A%2F%2Fraw.githubusercontent.com%2Fexcalidraw%2Fexcalidraw-libraries%2Fricochet-wasmcloud-and-wasm-1770917744834%2Flibraries%2Fricochet%2Fwasmcloud-and-wasm.excalidrawlib%3Fraw%3Dtrue)

### Using with Excalidraw MCP Server

When drawing diagrams with the Excalidraw MCP server, always:

1. **Use the wasmCloud library** — load components from the library above rather than drawing from scratch
2. **Use wasmCloud brand colors** in all diagram elements:
   - Primary: Green Aqua (`#00C389`) for main elements, connections, and accents
   - Backgrounds: Light blue (`#e5f2ff`), light gray (`#f4f7fa`, `#f8f9fa`)
   - Dark elements: Deep green (`#007054`), teal (`#00bc8e`)
   - Text/outlines: Gunmetal (`#253746`) or Space Blue (`#002E5D`)
   - Borders/dividers: Gainsboro (`#D9E1E2`)
3. **Avoid default Excalidraw colors** — replace them with the brand palette above

## Usage Guidelines

### When to Use Cosmonic Branding
- Cosmonic product interfaces and dashboards
- Cosmonic marketing materials
- Cosmonic documentation and websites
- Enterprise and commercial content

### When to Use wasmCloud Branding
- wasmCloud open-source project materials
- wasmCloud documentation and tutorials
- Community content and contributions
- Technical demonstrations

### Color Combinations

**Cosmonic:**
- Primary: Slate Purple (`#685BC7`) on white or Gainsboro backgrounds
- Dark mode: Light text on Space Blue (`#002E5D`) or Gunmetal (`#253746`)
- Accents: Yellow (`#FFB600`) for highlights and CTAs

**wasmCloud:**
- Primary: Green Aqua (`#00C389`) on white or Gainsboro backgrounds
- Dark mode: Light text on Space Blue (`#002E5D`) or Gunmetal (`#253746`)
- Accents: Yellow (`#FFB600`) for highlights and CTAs

### Accessibility

Ensure sufficient color contrast for text readability:
- Use Gunmetal (`#253746`) or Space Blue (`#002E5D`) for body text on light backgrounds
- Use white or Gainsboro (`#D9E1E2`) for text on dark backgrounds
- Test color combinations with WCAG contrast checkers
