Hmm.  The arguments to plot_args get sent directly to matplotlib's
contour command:

http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.contour

I think it might be "colors" and not "color".

Yes, but you need to do that manually when you create the axes[i][j]
objects you're feeding in.  If you're doing it via the multiplot
commands in yt, it's probably not going to happen.  But if you do it
manually via something like axes_grid, or jjust by manually creating
the axes inside a figure, it will be easier to adjust.
