Basically, a snow is a mix between amel and anery A (the more common type with more yellow). Snows are highly variable. I've seen pink, gray, yellow, blueish, and even greenish saddles on them.
Blizzard is a mix between amel and anery B, AKA muted or charcoal. Ideally, the snake should be pure white but there is still a faint pattern. And apparently now they have more yellow than they did when they first starting being produced.
I need to get a white snake. Don't even care what kind, they just look awesome.
