Color Palette Extractor

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

Instructions

When a user needs to extract colors from a source:

Identify Source Type:
- Image file (PNG, JPG, SVG)
- Website URL
- Screenshot
- Design mockup
- Existing color code to build palette from
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
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
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)
