Shading is a bit complicated in plot_surface(). In your particular case, it
is simply shading based on the results of calculating the normal vector of
each facet on the surface. It then normalizes the shading it has to do
based on what it has to get the full dynamic. This is why your image looks
the way it does (plus, there might be an issue where the normals for one of
your pieces is pointed inward instead of outward, probably due to the order
of the datapoints for the surface).
You can turn off shading altogether by simply passing shade=False as a
keyword argument to plot_surface().
I hope that helps!
