Theme Generator

Give it your brand colors. Get back a complete design system with semantic tokens, shade scales, and ready-to-use CSS variables or Tailwind config. Stop manually picking 9 shades of blue.

One command. Zero config. Just works.

Quick Start

npx ai-theme --primary "#3B82F6" --secondary "#10B981"

What It Does

Generates full color shade scales from your base colors (50 through 950)
Creates semantic tokens like success, warning, error, info
Outputs CSS custom properties, Tailwind config, or both
Ensures accessible contrast ratios between foreground and background
Builds consistent spacing and typography scales

Usage Examples

# Generate from primary color only
npx ai-theme --primary "#6366F1"

# Full brand palette
npx ai-theme --primary "#3B82F6" --secondary "#10B981" --accent "#F59E0B"

# Output Tailwind config
npx ai-theme --primary "#8B5CF6" --format tailwind

# Include dark mode variants
npx ai-theme --primary "#EC4899" --dark-mode

# Export to file
npx ai-theme --primary "#14B8A6" -o ./theme.css

Best Practices

Start with your hero color - The primary color sets the tone. Get that right first
Don't fight the generated scales - They're mathematically balanced. Trust the output
Test in context - Paste the variables into your project and see how they look on real UI
Customize after generating - Use this as a starting point, then tweak individual shades

When to Use This

Starting a new project and need a color system fast
Client gave you one brand color and expects a full palette
Converting a messy codebase to consistent design tokens
Exploring color options during early design phases

Requirements

No install needed. Just run with npx. Node.js 18+ recommended.

npx ai-theme --help

How It Works

The tool takes your base colors and uses color theory principles to generate harmonious shade scales. It calculates luminance values to ensure each step in the scale has proper contrast, then maps these to semantic purposes like backgrounds, text, and interactive states.
