Erebos
Enter the Dark Side
Erebos provides dark theming for web applications. It generates WCAG-compliant palettes, manages CSS variables and design tokens, and enables runtime theme switching without page reload.
Use Erebos when you need dark mode support, accessible color palettes, or a theming system for your web app.
How Erebos Works
Erebos builds theme tokens from a base palette. It computes contrast ratios and validates accessibility before output. The engine supports:
- Palette generation — Produce dark backgrounds with sufficient contrast
- Preview mode — Visualize themes in browser or terminal
- Export — Output CSS variables, JSON tokens, or design-system formats
Theme Commands
Run the theme generator:
# Generate palette from seed colors
./scripts/theme-gen.sh --palette "#1a1a2e" "#16213e"
# Preview in browser (opens local HTML)
./scripts/theme-gen.sh --preview
# Export tokens to stdout or file
./scripts/theme-gen.sh --export --format cssArguments
| Argument | Purpose |
|---|---|
--palette | Base colors for palette generation |
--preview | Launch preview mode (no file output) |
--export | Export theme tokens (requires format choice) |
