Colorize

Colorize[m]
generates an image from an integer matrix m, using colors for positive integers and black for non-positive integers.

Colorize[image]
replaces intensity values in image with pseudocolor values.

Colorize generates a pseudocolor image from a full array of integer values and arbitrary images, showing 0s and negative values in black.

ColorFunction	Automatic	how each pixel should be colored
ColorFunctionScaling	True	whether to scale the argument to ColorFunction
ImageSize	Automatic	the default displayed size of the image

All foreground pixels are colored the same in a binary image:

To highlight component using different colors, compute the connected components first:
