Color Palette Extractor from Images

Extracting colors from an image is a fundamental step in defining the visual identity of a web project. This online color palette extractor lets you upload any photograph or screenshot and process it locally in the browser, identifying the dominant tones scientifically. Using color quantization algorithms in the CIE L*a*b* color space, the tool does more than count similar pixels: it calculates the perceptual relevance of every shade to give you a balanced, coherent palette.

Once the colors are extracted, the tool organizes them for you by assigning strategic UI roles: a background color, a primary shade for dominant elements, an accent color for calls to action and a text tone — with the WCAG contrast ratio calculated in real time. That way you can design inclusive, accessible interfaces from the very first moment.

Frequently Asked Questions (FAQ)

How are the dominant colors calculated?

The image is analyzed pixel by pixel, reducing its palette through quantization (Median Cut). The resulting colors are then converted and ordered by their percentage coverage and their contrast against surrounding shades, to keep the palette harmonious.

Can I download the extracted colors?

Yes. You can copy CSS variables ready for your stylesheet, export the whole palette as JSON, or download the configuration files (.css and .json) directly to drop into your design system or into Tailwind.

Are my images kept private?

Absolutely. The entire image-processing pipeline runs 100% inside your web browser (client-side) through the Canvas API. No photo is ever uploaded to an external server or stored in a third-party database.
