Rene,
Unfortunately, you have stumbled upon one of the ugliness of the mplot3d
implementation. I am hoping to have more control available for the next
release. But right now, there is no way to turn off the axes spines
(because they aren't implemented as spines). If you really want to dig into
the source code, you could change the color argument to the Line2D call in
the init3d() method in matplotlib/lib/mpl_toolkits/axis3d.py
I am sorry I can not be more helpful.
