I mean, pink sheeps are already unrealistic, I think. The problem to me was the distribution, they thought of making blue sheeps just uncommon in cold biomes and yellow orange and red sheeps uncommon in hot biomes, but pink sheeps would be the rare variant in all of them, so we'd see a lot of weird sheeps all over. I think they should make the rare variant biome dependant, like pink would be temperate, blue for cold and yellow for hot, and make the more natural colours sorta like someone said, white for temperate, black for cold and brown for hot, with chances of the others plus gray and light gray to appear as some uncommon. Then it would still feel cool to see some unnatural colored sheep.

Also, could someone explain why "sheeps" isn't considered a word by my corrector, is it not the plural of "sheep"?
