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.
