I thought so until I put in cm.jet[255] and it maxed out. The
granularity of the 255 colours that I get from exporting the RGB
values is more than enough for the ranges of data I use. So I am happy
with that.

I am using PIL because I plan to plug in a Tkinter interface which can
directly accept PIL image instances.
