I believe we are probably in agreement. I do however believe that the animals that don't lack xanthophores that can not produce the red or yellow pigment may be called axanthic, however that would by technical definition be wrong. The prefix A in a-xanthic means lacking the xanthophore chromatophore. Just like hypo-xanthic would mean reduced xanthophores, and hyper-xanthic would mean more then normal xanthophores. I do not disagree that people would still consider an animal that has the xanthophore chromatophores that can not produce red or yellows still axanthic though just not by proper definition.
