Along the lines of Mike's suggestion, I thought this could be done using
Latex.
I posted an answer on SO with an example of doing this, but it seems only
to work with postscript backend. Other backends override the color with the
mpl text color setting.
Is there a way to prevent this override? For example don't try to use 'PS'
backend, and look at hte figure interactively. It defaults to black.
