[What exactly do genes do, then? What function do they serve? You could start with a consideration of the ~130 genes known to play a role in color. (Any why mutations in those genes alter color.)]
well I'm not going to play like I know all the functions of genes, but what I do know is they are not the end-all be-all of biology. The organism is not defined or controlled by its DNA...instead, the DNA is defined and controlled by the organism. Genes are followers in evolutionary change, not leaders. Genomes resist genetic change and generally only do so as a last resort.
