The BCC MultiTone Mix filter uses the source image’s color, luma, or alpha
information to create a toned image that uses up to five independent colors.
MultiTone Mix works by creating a color map based on a specific channel in the
source image, then replacing each color range in the map with a new color.
The built in PixelChooser, with integrated mocha planar tracking allows for
greater control over which areas of the image the filter should affect.
