Ok....
Umm, Let me tell you what I've heard, and then have people yell at me for begin wrong, lol.
Human, all mammal coloration actually, relies on only one factor that determines the amount of dark pigment that we have. Hence, if the person is devoid of all dark pigment, they have no color at all.
But Corn Snakes have three (or four) color-producing agents, one for black (similar to that found in mammals), one for red, and one for yellow (and one for irridescence that we don't totally understand). Hence, when all dark coloration is taken away in the same sense that it is in an "albino", there are still pigments being produced. Hence, the "albino" corn snake still having color. But it lacks all black, just like a mammal albino.
As for Anerys, or Black Abinos, the red and most yellow pigments are lacking in the same sense that black pigment lacks in an albino. So the paradox term of "black albino" does kind of apply.
As for snows and blizzards, they're not only lacking the black color producing agent, but also the agent to produce red and most yellow coloration. So, in a sense, while they take on the appearence of a mammalian albino, there are more factors at work then your typical albino.
And one more thing, names like "albino" and "black albino" are more marketing names to appeal to the public. I mean, doesn't "black albino" sound better then "anerythristic type 'a'"?
And more people know what an "albino" is then what an "amelanistic" is. So technically, a "snow" would be an "amelanistic type 'a' anerythristic". But that seems a bit long to me, lol.
Does this help? Or even make sense?
