Hello,
Just reporting if all is good with the mpl test suite.

[matplotlib-devel] Colormap that prints nicely in black and white
Hi all,
Don't know if anybody else has found a colormap that is aesthetically pleasing
and prints well in black and white. I found one after a lot of Googling.
Perhaps useful for plotting figures in journals that charge a lot for colour
figures. I got the colormap from:
http://ieeexplore.ieee.org/iel5/74/22101/01028735.pdf%3Farnumber%3D1028735
I decided to code it up (see attached text file for the cdict). If anybody
finds it useful, maybe it could go into the default colormaps that ship with
matplotlib.
cdict = {'red' : ((0.000, 0.00, 0.00),
(0.125, 0.15, 0.15),
(0.250, 0.30, 0.30),
(0.375, 0.60, 0.60),
(0.500, 1.00, 1.00),
(0.625, 0.90, 0.90),
(0.750, 0.90, 0.90),
(0.875, 0.90, 0.90),
(1.000, 1.00, 1.00)),
'green' : ((0.000, 0.00, 0.00),
(0.125, 0.15, 0.15),
(0.250, 0.15, 0.15),
(0.375, 0.20, 0.20),
(0.500, 0.25, 0.25),
(0.625, 0.50, 0.50),
(0.750, 0.75, 0.75),
(0.875, 0.90, 0.90),
(1.000, 1.00, 1.00)),
'blue' : ((0.000, 0.00, 0.00),
(0.125, 0.50, 0.50),
(0.250, 0.75, 0.75),
(0.375, 0.50, 0.50),
(0.500, 0.15, 0.15),
(0.625, 0.00, 0.00),
(0.750, 0.10, 0.10),
(0.875, 0.50, 0.50),
(1.000, 1.00, 1.00))

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.
