Color Palette Extractor

This free online color palette extractor pulls the dominant colors out of any photo, screenshot or piece of artwork and turns them into a usable, exportable palette — hex codes, RGB values, CSS custom properties and a ready-to-paste Tailwind config, not just a row of swatches to eyeball. It's built for the moment a designer or developer needs to match a brand's colors from a reference photo, pull a palette from inspiration art, or turn a product shot into a coordinated color scheme for a page design.

Under the hood it runs a real k-means color clustering algorithm — the same category of technique professional color tools use — grouping every pixel in the image into the number of color clusters you choose, then reporting each cluster's average color and how much of the image it actually covers. That's meaningfully more accurate than naive approaches that just grab the most common individual pixel values, which tend to get thrown off by noise and compression artifacts and miss the colors a person would actually call "dominant."

The palette updates live as you drag the color-count slider from 3 up to 10, and a toggle switches the swatch order between dominance (largest color areas first, the default) and hue (arranged like a color wheel, useful for spotting a scheme's overall temperature and balance at a glance). Every swatch is click-to-copy for its hex code, and the export row goes further: copy the whole palette as CSS custom properties ready to paste into a stylesheet, copy it as a Tailwind `colors` config block ready to drop into a project, or download a labeled PNG swatch strip for a mood board, a client deck, or quick reference outside the browser.

Everything runs locally in your browser using the canvas API — nothing is ever uploaded to a server, so it's instant, works identically on a phone or a laptop, and is safe to use on unreleased work, client photos or anything else you'd rather not send anywhere.
