Actually, I have been looking at a somewhat related problem.  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.
