``` 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
