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 css

Arguments

Argument	Purpose
--palette	Base colors for palette generation
--preview	Launch preview mode (no file output)
--export	Export theme tokens (requires format choice)
