Color "adjustment" and causing actual physical deformities are much diffrent. I too like some of the fish that have been bred to have different color strains. Shoot, that's what all the betta's you can purchase in the store have had bred into them. You aren't going to find that color betta in the wild. However, those poor "brain" goldfish are sad, sad cases. The plain ol fantails aren't so bad, but the "bubble eyes" and such are too much for my liking. It would be similar to trying to breed people with huge heads or extra arms.
