I've been thinking a lot lately about how CSS could be used to specify
styles in matplotlib. It would allow one to specify any set of styles
to cycle through (colors, linestyles, whatever other properties).
axes.nth-child(0) { color: blue }
axes.nth-child(1) { color: green }
vs.
axes.nth-child(0) { dashes: dotted }
axes.nth-child(1) { dashed: dashed }
The obstacles to integrating something like that are that a) matplotlib
currently doesn't maintain the fact that a plot's style was "unset" at
the time of creation, and b) the heirarchy of plot objects is a little
tangled, so it would be hard to specify using CSS selectors what should
be styled.
It does keep popping up in my brain as a clean and complete solution to
the problem of styling, but there would need to be a number of changes
to the internal plumbing to make it work.

Did anything ever come of the MPL black and white mode

having an

activated with a keyword argument would be very handy.

Perhap's Tony Yu's mpltools might be the closest we have
gotten to this goal. There has been a number of technical
hurdles that I have not had the time or resources to iron
out. Hopefully, it will be helpful to you.

Thanks for the advertisement Ben ;)
Will: If you're just interested in grayscale plotting, here's a
direct link to the example:
http://tonysyu.github.com/mpltools/auto_examples/style/plot_grayscale.html
The discussion that you link to talks specifically about line
styles. In the past there's been discussion of adding a linestyle
cycle rc param, but I don't think there's been progress on that front.
BTW, Ben: are you still thinking about some sort of hierarchical
configuration management? I think it'd make a great MEP, if you
find the time.
Not necessarily a hierarchical config management, but rather a
hierarchical property management. Of course, this was before I
discovered GraphicsContext, which makes me wonder if it could be
generalized and moved out of the backends to serve such a purpose.
Of course, with regards to rcparams, we definitely need to re-examine
how we are doing it right now before it gets too bloated...
