Documentation

Color Palette Extractor

Extract dominant colors from images and generate color palettes with multiple export formats.

Features

  • Dominant Colors: Extract N most dominant colors using K-means
  • Color Schemes: Generate complementary, analogous, triadic schemes
  • Multiple Formats: Export as CSS, JSON, ASE (Adobe Swatch), ACO (Photoshop)
  • Color Analysis: RGB, HEX, HSL, HSV values
  • Visualization: Palette swatches, color distribution charts
  • Batch Processing: Extract palettes from multiple images
  • Similarity Matching: Find similar colors across palettes

Quick Start

from color_palette_extractor import ColorPaletteExtractor

extractor = ColorPaletteExtractor()

# Extract colors
extractor.load('image.jpg')
palette = extractor.extract_colors(n_colors=5)

# Export
extractor.export_css('palette.css')
extractor.export_json('palette.json')
extractor.save_swatch('swatch.png')

CLI Usage

# Extract 5 colors
python color_palette_extractor.py --input image.jpg --colors 5 --output palette.json

# With CSS export
python color_palette_extractor.py --input image.jpg --colors 8 --css palette.css --swatch swatch.png

# Batch mode
python color_palette_extractor.py --batch images/ --colors 5 --output palettes/

Meta

This Claude Skill creates original algorithmic art using p5.js with seeded randomness and interactive parameters. It generates .md files for algorithmic philosophies, plus .html and .js files for interactive generative art implementations. Use it when developers need to create flow fields, particle systems, or other computational art while avoiding copyright issues.

subagent-driven-development

Development

This skill executes implementation plans by dispatching a fresh subagent for each independent task, with code review between tasks. It enables fast iteration while maintaining quality gates through this review process. Use it when working on mostly independent tasks within the same session to ensure continuous progress with built-in quality checks.

executing-plans

Design

Use the executing-plans skill when you have a complete implementation plan to execute in controlled batches with review checkpoints. It loads and critically reviews the plan, then executes tasks in small batches (default 3 tasks) while reporting progress between each batch for architect review. This ensures systematic implementation with built-in quality control checkpoints.
