Image Color Extractor

Some of the best palettes don't come from a color wheel — they come from the world. A photograph, a piece of packaging, a film still, a brand's hero shot already contains a coherent set of colors that nature or a photographer balanced for you. The trick is extracting the representative colors rather than a random sampling of pixels, and that's a quantization problem: bin the millions of pixels into a manageable grid, count which bins are most populated, and report the average color of each. What falls out is the image's actual color story, ranked by how much of the frame each color owns.

Coverage is the insight people overlook. The colors at the top of the ranking are usually the quiet ones — sky, wall, skin, background — and the colors that make an image feel like that brand are often near the bottom, a small but vivid sliver. So reading an extracted palette well means not just taking the top color, but scanning for the high-impact, low-coverage hue that wants to be the accent. The proportional strip makes this obvious at a glance.

Doing this in the browser matters more than it sounds. Color extraction is exactly the kind of task people run on unreleased product shots, confidential client mockups, and personal photos — none of which should be uploaded to someone's server to pull six hex codes. Reading the pixels locally with a canvas keeps the image on your device, makes the result instant, and works offline. Privacy isn't a feature bolted on; it's the correct default for a tool that touches your images.

Extraction is the start, not the end. Raw colors from imagery are on-brand but unstructured — to ship them you expand the chosen ones into scales, build harmonies, and check contrast. So pull the palette here, then hand it to the Scale Generator, the Palette Generator and the Accessibility Checker to turn a beautiful photo into a working color system.
