[Matplotlib-users] redefining color keywords in stylesheets

Thanks for the update !

The ability to use properties 0,1,2 looks very useful. The notation
'[n]' looks a bit heavy, but I guess this is necessary to avoid clashing
with the existing behavior (linewidth=0 vs. linewidth='[0]'...).

As for the palette, I think it's very similar to what I was proposing.
Only putting things in the rcParams is maybe simpler because it is
compatible with the existing stylesheet mechanism. For me, the palette
should just be one aspect of the style.

Things could be as simple as having 'color.b', 'color.g', ... keys added
to rcParams. (or 'palette.b'...)
