It might be a useful feature in matplotlib.color to provide a function that can take a colormap and produce a grayscale version of it. In my limited amount of research, I have found that one could convert the rgb values into hsv or hsl and use the "value" or "lightness" respectively for the grayscale value. I forget which one was aesthetically better, though. Ben Root
