Workflow
Identify the source: image file (PNG, JPG, SVG), website URL, screenshot, design mockup, or an existing color code to build from.
Extract colors.
- From an image: analyze pixel data, identify dominant colors, group similar shades, calculate frequency, and sort by prominence.
- From a website: fetch and parse the CSS, extract color values, and identify brand, accent, text, and background colors.
- Cluster with K-means; extract 5-10 dominant colors. Ignore near-white and near-black unless significant.
Build the primary palette (5-10 colors): most dominant color, 2-3 supporting colors, 1-2 accents, a background, and a text color. Generate an extended palette with tints, shades, tones, and 50-950 numeric scales. See references/color-theory.md.
Run color harmony analysis to produce complementary, analogous, triadic, split-complementary, tetradic, and monochromatic schemes. See references/color-theory.md.
Check accessibility: compute WCAG 2.1 contrast ratios for each text/background pairing and test against protanopia, deuteranopia, and tritanopia. Recommend accessible alternatives where a pairing fails. See references/color-theory.md.
Format the report following references/output-template.md, and export to the requested formats using references/export-formats.md.
Output Requirements
Deliver palettes that have clear dominant colors, sufficient variations, semantic naming, harmony schemes, contrast ratios that pass accessibility checks, usage guidelines, and exports in multiple formats. Produce professional, accessible palettes ready for immediate use in design systems.
