Color Palette Extractor

Color Palette Extractor

Extract and generate color palettes from images, websites, and designs.

Instructions

When a user needs to extract colors from a source:

1. Identify Source Type:

   • Image file (PNG, JPG, SVG)
   • Website URL
   • Screenshot
   • Design mockup
   • Existing color code to build palette from

2. Extract Colors:

   From Image:

   • Analyze pixel data
   • Identify dominant colors
   • Group similar shades
   • Calculate color frequency
   • Sort by prominence

   From Website:

   • Fetch and parse CSS
   • Extract color values from stylesheets
   • Identify brand colors
   • Find accent colors
   • Detect text/background colors

   Color Clustering:

   • Use K-means clustering
   • Group similar colors
   • Typically extract 5-10 dominant colors
   • Ignore near-white/near-black unless significant

3. Generate Color Palette:

   Primary Palette (5-10 colors):

   • Most dominant color
   • 2-3 supporting colors
   • 1-2 accent colors
   • Background color
   • Text color

   Extended Palette:

   • Light and dark variations
   • Tints (add white)
   • Shades (add black)
   • Tones (add gray)
   • Generate 50, 100, 200...900 scales

4. Color Harmony Analysis:

   Generate complementary schemes:

   • Monochromatic: Variations of single hue
   • Analogous: Adjacent colors on wheel
   • Complementary: Opposite colors
   • Triadic: Three evenly spaced colors
   • Split-complementary: Base + two adjacent to complement
   • Tetradic: Four colors (two complementary pairs)

5. Format Output:
