That's right, following matplotlib's defaults.

There are two options to create a plot with a black background color.  The
first is to pass the 'facecolor' keyword argument down to matplotlib when
calling the save function.  Unfortunately since the foreground is black by
default, you'll also have to adjust the colors of all of the axes, tick
marks, axes text, colorbars, etc to be white. Here is an example notebook
that does this:

Another option would be to adjust the matplotlib defaults in your
matplotlibrc (http://matplotlib.org/1.3.1/users/customizing.html) so that
figures have a black background by default.

I have to say that I kind of like the way the black background looks and
could definitely see it being useful in some situations.  I don't think it
would be very hard to add a "set_black_theme" function that does more or
less what my notebook does.  That would probably be a nice afternoon hack
for someone that wanted to familiarize themselves with yt's plotting code.

Hope that's helpful,

Nathan
