Can someone clarify on these two "morphs"? I serached all through the forums here and found some decent info on Harlequins but I still couldn't pick one out of a pile of normals. As for black backs, I found a whole lot of nada. All the black back photos that users have posted have blushing on the backs, making them brown and not 100% black. So why the name? Aren't all normals black backs when you think about it? What gives?
