We show that the $\gamma$-vector of the order complex of any polytope is thef-vector of a balanced simplicial complex. This is done by proving thisstatement for a subclass of Stanley's S-shellable spheres which includes allpolytopes. The proof shows that certain parts of the cd-index, whenspecializing $c=1$ and considering the resulted polynomial in $d$, are thef-polynomials of simplicial complexes that can be colored with "few" colors. Weconjecture that the cd-index of a regular CW-sphere is itself the flag f-vectorof a colored simplicial complex in a certain sense.
