Once the framework is in-place, that is certainly possible.  I agree that
the current list is probably too short and could use 3 or 4 more values.

Agreed.  Having blue and then green has always annoyed me.  However, I am
hardly a color expert, and I would greatly welcome input from the peanut
gallery (possibly from the same people pushing for a change in the default
colormap?)

A new feature added in v1.1.0 was the ability to specify custom line
styles, and a quick look through the line styles available in LibreOffice
could be an inspiration for some more standard styles.

The idea is that since these are all configurable through the rcparam
mechanism, standard profiles can be created with various combinations of
settings and all a user (or a convenience function) has to do is
"matplotlibrc.update(mystyle_profile)".  Note, this wouldn't be a "live"
switch of styles.  In other words, once an element has been plotted,
changing the profile will not update those plot elements.
