Image-to-Color-System Compiler for Claude Skills

---

Hexed

Hexed is a Claude skill that extracts structured color systems from images.

What It Does

• Accepts 1-5 images (PNG, JPG, WebP)
• Extracts dominant colors using histogram analysis
• Builds a complete design system with:
  • Core colors (primary, secondary, accent)
  • Neutral ramp (10 steps)
  • Semantic colors (success, warning, error, info)
  • Light and dark UI themes
• Exports to CSS variables, Tailwind config, or Figma tokens

Installation

For Claude Users

Install Hexed from the Claude Skills marketplace:

1. Go to Settings → Skills
2. Search for "Hexed"
3. Click "Add Skill"

See INSTALLATION.md for detailed instructions.

For Developers

To run locally or integrate into your own projects:

pip install pillow numpy
python test_hexed.py path/to/image.png

Files

• SKILL.md - Instructions for Claude on how to use the skill
• hexed_compiler.py - Core color extraction and system building logic
• hexed_exports.py - Export utilities (CSS, Tailwind, Figma)
• test_hexed.py - Test script to verify functionality

Usage

When a user uploads images and asks for color extraction:

1. Check /mnt/user-data/uploads/ for images
2. Import and run the compiler:

   from hexed_compiler import compile_from_images
   result = compile_from_images(image_paths)

3. Export to desired format:

   from hexed_exports import export_css_variables
   css = export_css_variables(result['color_system'])

4. Save to /mnt/user-data/outputs/ and present to user

See SKILL.md for complete usage instructions.

Testing

To test the skill:

python test_hexed.py /path/to/image1.png /path/to/image2.jpg

This will:

• Process the images
• Show extracted colors
• Generate all export formats
• Save outputs to test_output/

Algorithm

1. Resize: Images scaled to 768px max dimension
2. Quantize: Colors bucketed into 24-step buckets (faster, coarser grouping)
3. Histogram: Count pixel frequencies per bucket
4. Rank: Sort by frequency
5. Pick: Select top 8 distinct colors (40+ RGB distance minimum)
6. Map: Assign extracted colors to structured system roles

Export Formats

CSS Variables

:root {
  --color-primary: #3B6EF5;
  --neutral-500: #7E8AA3;
}

[data-theme="light"] {
  --background: #F7F8FA;
}

Tailwind Config

export default {
  theme: {
    extend: {
      colors: {
        primary: "#3B6EF5",
        neutral: { "500": "#7E8AA3" }
      }
    }
  }
};

Figma Tokens

JSON compatible with Tokens Studio for Figma plugin.

Limitations

• Max 5 images per compilation
• Images resized to 768px for processing
• Deterministic but approximate (histogram-based)
• No image generation or layout creation
• Each compilation is independent (no persistence)
