"Stretched color" images actually are used pretty often by the JPL teams to look more closely at color variations; you can see a fair number of them on the rover website--they're the ones with a gray or purple sky, and the little concretions in the Opportunity Meridiani Planum pictures are sky-blue--but there isn't any attempt to keep the average hue constant, I think.
