Scientifically there are no names given to individual color morphs. This means that unless there is a certifying authority, there will not be conformity in naming. Of course, then you would end up paying double for "certified" true zoas.
This even goes on with dogs to a lesser extent. I've seen places calling hybrid dogs (mutts), all sorts of names, and trying to jack up the price by doing so.
I buy corals that I like the look of, and don't know the names for some of them, nor do I care. My dog is a mutt, but a good looking one that comes when I call (most of the time). Life's easier when titles don't matter.
