Most beneficial mutations tend to affect things that are not visually apparent, e.g. disease resistance, digestion, etc. A mutation with a strongly visual effect might be discriminated against, but that depends on the situation. You might be interested in reading about the Doma Tribe in modern Zimbabwe [1], where a mutation affecting feet causing "lobster claw syndrome" aka entrodactyly became common. Initially children born with this syndrome were rejected, but as it was locally common enough it eventually became accepted.
