Color Palette from Image

Upload any image and extract the dominant color palette — up to 16 hex, RGB, and HSL swatches.

How color extraction works

The image is drawn onto an offscreen canvas and its pixel data sampled. Pixel colors are quantized into a reduced color space (32-level buckets per channel) to cluster similar hues together, then sorted by frequency. Colors that are too similar (Euclidean distance < 48) to an already-selected color are skipped to ensure palette diversity. The result is the n most visually dominant colors in the image.

All processing is done locally in your browser — no image data is uploaded. For related tools see Color Converter, Color Palette Generator, and Color Temperature Converter.
