- exportAsTailwind() - Tailwind config module export
- exportAsJSON() - Structured JSON with color objects
- exportAsJavaScript() - JavaScript array of colors
- downloadAsFile() - Browser download helper
- ExportColor interface for typed exports
**ExportMenu Component:**
- Format selector dropdown (5 formats)
- Live preview of export code
- Syntax-highlighted code display

**Export Formats:**
