Currently, it is not possible to change the legend font color in Sage at
all.
[http://permalink.gmane.org/gmane.comp.python.matplotlib.general/24674
This link] shows how to do it in matplotlib - it is not straightforward in
matplotlib either.
I think the way to introduce it is
1. Allow a `legend_color` parameter to each plot.
2. Keep track of the individual legend colors via a key in the
`Graphics._legend_opts` dictionary.
3. The key will contain a list of colors, defaulting to black or None (I
prefer None, so that we use matplotlib's default).
4. After all the plots have been rendered and the legend as been set, we
can follow the method in the link above to extract all the texts and set
the colors individually, skipping the ones which are None (if the default
is None).

Apply [attachment:trac_14580-legend_color.patch] and
[attachment:trac_14580-more-colors.patch] to devel/sage.
