Same remark as before: use the same as I did in the other PR: ``self.kwds.setdefault('c', self.plt.rcParams['patch.facecolor'])``, because how you did it here will overwrite c if the user has given it a specific value. So the user will not be able to specify a color. With the `setdefault`, it will only be set to ``plt.rcParams['patch.facecolor']`` if the user hasn't specified a ``c``.
