This method takes a triple ( containing the three CMY parameters of a color, and
returns the equivalent color as a c, m, y)Color instance.

def paramsToColor ( self, params ):
"""Convert CMY parameters to a Color.

Each parameter is the complement of one of the RGB colors: cyan
is opposite red, magenta is opposite green, and yellow is
opposite blue. Mathematically, we can convert a value by
subtracting it from MAX_PARAM.
cyan, magenta, yellow = params
red = MAX_PARAM - cyan
green = MAX_PARAM - magenta
blue = MAX_PARAM - yellow
return Color ( red, green, blue )
