Summary
Pulls color palettes from images, websites, or screenshots and exports them in whatever format you need: HEX, RGB, HSL, Tailwind config, CSS variables, even iOS and Android formats. It does K-means clustering to find dominant colors, generates full shade scales (50-900), and checks WCAG contrast ratios so you know if your text will actually be readable. The color harmony analysis is handy when you need complementary or triadic schemes. Honestly most useful when you're reverse engineering a design you like or need to quickly build a design system from a brand asset. Beats manually eyedropping colors and doing contrast math yourself.

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 usingreferences/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.
Example Triggers
- "Extract colors from this screenshot"
- "Get color palette from this website"
- "Generate a color scheme from this image"
- "Create Tailwind config from these colors"
- "Find dominant colors in this logo"
- "Build a palette from this hex code"
