Hello,
Attached is a small patch to add a simple color mix operation support.
For example, "red!30!white" mixes 30% of red with 70% of white. The
syntax is borrowed from latex xcolor package
(http://www.ukern.de/tex/xcolor.html).
I found it quite handy with the fancy box thing.
plt.text(0.6, 0.5, "test", size=50, rotation=30.,
bbox = dict(boxstyle="round",
fc="orange!20!white", # 20% orange + 80% white
ec="orange!50!white", # 50 % orange + 50% white
)
)
plt.text(0.5, 0.4, "test", size=50, rotation=-30.,
bbox = dict(boxstyle="square",
fc="aqua!50!green!20!white",
ec="green!40!white",
)
)
Any chance this could be included in matplotlib?

color_mix.diff (1.38 KB)
That's a cool feature, and one I have not come across before.
I hesitate slightly because this it is non-standard (by that, I mean not available in a lot of "mainstream" formats like CSS, SVG etc.), but maybe that's just because they aren't as cool as matplotlib... 
The nice thing is that the "!" isn't meaningful in color strings at present, so this new syntax is at least unambiguous with anything pre-existing.
I'm for it, but would like to hear from others first.
Cheers,
Mike

I like it too -- I only ask Jae-Joon that you make sure it is properly
documented, eg in the matplotlib.colors docstring. What would be
really nice would be a section in doc/users_guide on mpl colors....

Thanks for the positive feedback!
Okay, I'll add a proper documentation for it and upload the patch again.
