Color quantization is a process which reduces the number of colors in an image. Most bitmap editors perform color quantization when converting an image with many colors to an image format with less colors, such as Photoshop's Mode→Indexed Color. Ideally, the palette of the new image should be chosen so that the new image is as visually similar as possible to the old image. The most popular algorithms are the median cut and octree algorithms. Color quantization is frequently combined with dithering, to hide artifacts such as banding that it causes.
