Actually, "albino" MEANS lacking melanin (or amelanistic). "Albino" only means "white with red eyes," phenotypically speaking, in mammals because we only produce one pigmentation: melanin. All our variations in coloration are due to melanin.....and there are only 3 forms of melanin we can have. (One of those doesn't provide external coloration).
In snakes, with more than one coloration, an albino is typically now a solid white snake. "Amelanism" is synonymous with "albinism." A snow is ia anerythristic albino (in cornsnakes). It is just a common misconception, but a misconception no less, that an albino has to be white with red eyes across all taxa.
