It's not as though the chemical that causes the coloration might have other effects of some benefit to the organism, or that the genes responsible might be linked to other genes, or that the impact of the pigment on number of descentdants might be small enough that genetic drift could produce variety.

After all, anybody claiming that coloration is a problem for current theory would have already been thorough about ruling out those hypotheses, right?
