You'll probably find that a "snow" IS a "white albino" at least in terms of corn snakes - because Corn Snakes have more than just melanin (which makes black or brown in mammals) making up their colours, they have a couple of things that reduce colour.
First, there's the no-black albino "Amelanistic" which is a red/orange snake with red eyes.
Second, there's the no-red albino "Anerythristic" which is a grey and black snake with grey-normal eyes.
Lastly, you get your no-black, no-red "Snow" (which is really Anerythristic + Amelanistic) which is a pale coloured snake - sometimes they get pinkish, orangish or greenish-yellow tones - with red to pink eyes.
If you want something that's as close to a mammal albino like a white mouse or bunny, a snow or a blizzard is probably your best choice.
