Extract color palettes from images, websites, or designs. Identifies dominant colors, generates complementary schemes, and exports in multiple formats (HEX, RGB, HSL, Tailwind, CSS variables). Use when users need color schemes from images, brand colors, or design system palettes.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# 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)

How to install

The exact contents, by fingerprint

mdr add nicepkg/ai-workflow/color-palette-extractor@sha256:d7890677ce46ba45

The line at the top of this page pins the label git:20260118.be84779, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
