Dominant Color Finder — Free Online
Find the dominant color in an image. Useful for skinning UIs, picking accent colors that match a hero photo, or sorting a photo library by color.
How dominance is calculated
K-means clusters every pixel into color groups. The cluster with the largest pixel count is the dominant color. Set the cluster count to 1-2 for a strong dominant; 5-7 for a full palette.
