I just made a chance in svn to expose the default color list. Here is an ipython session that shows how to use it: In [1]: import matplotlib.axes as mplaxes In [2]: x, y = rand(2,100) In [3]: plot(x, y, 2*x, 2*y) Out[3]: [<matplotlib.lines.Line2D instance at 0x8f2dc8c>, <matplotlib.lines.Line2D instance at 0x8f2dd6c>] In [4]: mplaxes._process_plot_var_args.defaultColors = ['red', 'darkslategray', 'wheat'] In [5]: clf() In [6]: plot(x, y, 2*x, 2*y) Darren, we might want to expose this in the matplotlib.conf, but perhaps is it a rare enough request that it is enough to let people tweak it manually when needed. The only thing that is a bit ugly is that Axes._process_plot_var_args has the leading underscore indicating it should not be used outside of mpl, but this is easy enough to remedy...
