Hi Andrew,

Is there a way to set the background color for projection plots? I'd like to set it to be black instead of white, which I assume is the default.

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: http://nbviewer.ipython.org/gist/ngoldbaum/7367380cbe6683159da5

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
