About this tool
Upload any image to extract its dominant color palette. Get ready-to-use color values in HEX, RGB, and HSL, plus code snippets for CSS and Tailwind.
- Builds a weighted 5-bit RGB histogram from visible sampled pixels, then applies median-cut buckets and near-duplicate merging.
- Ranks each distinct cluster by sampled coverage and exposes HEX, RGB, HSL, CSS, Tailwind, and JSON values.
- Checks image signatures and source limits before sampling and ignores pixels below 6% opacity.
- Exports a verified labeled PNG strip and a source-linked JSON report.
How to use Color Palette
Rank weighted color clusters from visible image pixels and export HEX, RGB, HSL, code, PNG, and JSON evidence.

Examples you can test
Load an example, compare the result with the expected output, then replace it with your own input.
Extract colors from a product image
Example input
Image: product-hero.jpg
Expected output
Dominant HEX, RGB, and HSL colors
Palette extraction helps match landing-page accents or design tokens to an existing visual asset.
Build a brand-adjacent palette
Example input
Image: app-screenshot.png
Expected output
Set of representative interface colors
Use extracted colors as a starting point, then check contrast and accessibility separately.
Validation checklist
- Check extracted colors against accessibility contrast requirements before using them for text.
- Ignore transparent or background-heavy colors when the subject is the real design target.
- Sample multiple images if one asset does not represent the full brand palette.
- Compare extracted colors with existing brand tokens before introducing new values.
- Review colors on real UI backgrounds because dominant image colors are not always usable interface colors.
