ColorConvert[expr, colspace] converts color specifications in expr to refer to the color space represented by colspace.

TooltipBox["9~"]BinaryImageQ[image] yields True if image has the form of a binary Image or Image3D object, and False otherwise.

ColorNegate[image] gives the negative of image, in which all colors have been negated. FColorNegate[color] gives the negative of a color.

ColorSpace is an option for Image and related functions that specifies the color space to which color values refer.

ColorQuantize[image, n] gives an approximation to image that uses only n distinct colors.

TooltipBox[" "]ColorSeparate[image] gives a list of single-channel images corresponding to each of the color channels in image. 8+ColorSeparate[image, colorspace] gives a ...

DominantColors[image, n] returns at most n dominant colors in image.
