Maybe we don't need any more color schemes; I certainly don't have anything
in mind. I just use the default one all of the time.
Rather than a Makefile target, a Sage command to change on-the-fly would be
nice. You might investigate whether IPython allows changing color schemes
while it's running, or if it needs to be restarted for such changes to take
effect. If the former, just provide access to that command. If the latter,
at least updating the Installation guide with information about how to
change it would be a start. A Makefile target is not appropriate since a
sysadmin may be building and installing Sage for many users; instead, you
want a run-time solution. Maybe a command-line flag ("sage --color=...")?
This would just pass the appropriate configuration option to IPython.
Also note http://trac.sagemath.org/ticket/14713, which updates the version
of IPython in Sage. I'm guessing that the changes on that ticket will be
available in the next beta release.
