I have an OB Peacock tmale hat mated with a non-descript "yellowish" Walmart female peacock (hand selected by my daughter who calls her miss sunshine so the darn fish is here to stay). All of the offspring are this sad yellowish color, though a few do have a blotch or two on their forehead area. I know I should do the right thing with these guys and put them out of their misery, but do OB babies "blotch up" as they age? I might keep a few on the side just to see what they turn into.
