This class implements the CMY color model. It is a concrete class
that inherits from the
ColorModel abstract class.
There is little more logic here than in the
RGBModel class, since each parameter is the complement of one of the RGB
parameters used internally by the
# - - - - - c l a s s C M Y M o d e l class CMYModel(ColorModel): """Represents the cyan-yellow-magenta color model. """
