One of my first attempts at a contribution to matplotlib three
years ago was related to this. It was in reply to a similar
question on list, and I wrote a patch, but never saw it through
to inclusion because it wasn't something I needed.

I think it's a helpful starting point, as I include a discussion
on the limitation of mpl colormaps there.
