Why is this little guy a cremello? He's not.
Just trying to understand the whole palomino/cremello/perlino coloring..
Bay + 1 cream gene = Buckskin
Bay + 2 cream genes = perlino
Black + 1 cream gene = smoky black
Black + 2 cream genes = smoky cream
Chestnut + 1 cream gene = palomino
Chestnut + 2 cream genes = cremello.
Your foals dam is bay, carrying no cream genes (bc they can't hide), so he can only be a "single dilute".. Smoky black, Buckskin or Palomino.
