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 five orbits under the second D2h sub-symmetry (specified
as subsymmetry number 1) of the model.
The following command assigns different colours
to the different kinds of face.
