upon extracting the face color of a matplotlib.path.Path object,
fc = obj.get_facecolor()
I always seem to get an array of length 4. This initially led me to
believe I'm dealing with CMYK values, but it really seems like the
last entry is *always* 1.0 and the first three give the RGB
representation of the respective color.
Is there any documentation on color codes usage in matplotlib?
