color a portion of a sphere surface

How would I color just the portion of the surface of the sphere below connected by the 4 black dots? The fill3 or patch function do not work because the surface is curved and not flat.

lmac456: May I ask to see the code that you used to generate your plot? I'm trying to do something similar, but with hexagonal sections.

Each face of the sphere is locally flat for drawing purposes. If that is too "rough" then you would need to create additional faces that subdivide to get a finer approximation to curvature.

I keep running into this same problem using the patch function even with setting FaceColor to flat (attached image). Is this what you mean by the face possibly being too "rough"?

Can you attach the data file for the shape?
