I don't really use pie charts, but I think it just uses the default color
cycle. This can be altered by changing the rcParams:

>>> import matplotlib.pyplot as plt
>>> plt.rcParams['axes.color_cycle'].remove('k')

The color_cycle parameter is just a python list, so I use list.remove to
remove black (which is the letter 'k' since 'b' is blue). There are other
ways of setting rcParams, as detailed in the help
files<http://matplotlib.sourceforge.net/users/customizing.html>(Note
that `rc` and `rcParams` is in both matplotlib.pyplot and the main
matplotlib package).
