Isn't this closely related to the idea we've tslked about a number of
times (mostly off list) to supplant the colormap infrastructure with a
"DiscreteColormap" or something along those lines, which mapped data
to a set of discrete colors, using nearest neighbor or what have
you. Then you would have the best of both worlds: your favorite
colors and consistency with the mpl colorbar/colormapping API. Would
this work?
