Hi,
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?
Cheers,
Nico

Hi,
maybe:
http://matplotlib.sourceforge.net/api/colors_api.html#module-matplotlib.colors
"RGB and RGBA are sequences of, respectively, 3 or 4 floats in the range 0-1."

"RGB and RGBA are sequences of, respectively, 3 or 4 floats in the range 0-1."
That would explain it. It also seems that I never ever will have to
worry about CMYK values as they don't seem to be used anywhere in
matplotlib as a search on the website for "cmyk" suggests.

Correct. Matplotlib currently does not support CMYK representation. The fourth element is the alpha (transparency) value.
