The one way to do it is to patch the source code in the following way.
in mpl_toolkits/mplot3d/axes3d.py, at around line 2355, replace the line:
sfacecolors = self._shade_colors(facecolors, normals)
with
sfacecolors = facecolors
Could you file a github issue requesting a keyword argument to turn this
on/off?
Cheers!
