A symmetrical colouring can be made by colouring the elements
according to symmetry orbits.
In this example, the square faces of the rhombicuboctahedron
fall into two orbits under
the full symmetry of the model (faces on 4-fold axes and faces
on 2-fold axes). The following command assigns different colours
to the different kinds of face.
