How can I change the color of tiles in a spherical graph?

Hello,
I need to change color of every tile, so the sphere is a heat map just like this image.

This is just image that we got from our teacher, but i have no clue how to make it.

sphere
axis equal
colorbar
If you want to change the colors, you can plot the sphere using surf(X,Y,Z,C) where C controls color of each face.
Use the [X,Y,Z] = sphere syntax to return the x,y,z coordinates and then use h=surf(X,Y,Z) to produce the same sphere and return the surface handle. You can also control color by updating properties of the surface object h.

In S1 you can see the properties.
You can use the Cdata propery to change the color of each tile for example.
[X,Y,Z] = sphere;
figure
s1 = surf(X,Y,Z)
colorbar;
axis equal
figure;
s2 = surf(X,Y,Z)
s2.CData = zeros(21,21,3);
s2.CData(12,3,:) = [1 0 0] % R G B
