I guess I should atleast read the docstring for plt.pie before giving you
advice on how to use it. It looks like the default colors are hard coded
into the function (instead of using the color_cycle parameter).

The quickest way to create different colors is to pick them out from a
colormap. For example, the following gives decent results:

>>> colors = plt.cm.Set1(np.linspace(0,1,9))
>>> plt.pie(np.ones(9), colors=colors)

Of course, trying to get more (visually-differentiable) colors out of the
color map will be difficult.

Hope that helps,
