Thank you for your answer but it does not work like I want.
The colors are always the same. Yellow and Black don't change with
the position of the mesh.
In the example of the Wolfram Website one of the color change.
I think the program uses the function ColorFunction but there is only
one ColorFunction and it is used in the the line MeshShading -> {Black,
Automatic}.
I would want that the Color Black changes also.
Thank you
