That's pretty much it. Kelli Hammack also has a 'hypomelanistic' phase that hasn't been proven out yet. Ghost is theoetically hypomelanistic x axanthic, but I really have no idea what mine is. There's also a possibility of genetically striped Kenyans. And... well... I guess we'll have to see about piebalds. But at any rate the PROVEN morphs are albino, axanthic, and paradox albino.
