Albino and Pastel albinos

Hey everyone, I'm curious on what the best way to tell an albino from a pastel albino is. Should I go off of a white head and clear belly for an albino pastel? I feel like my albino girl has a clean belly now and it's hard to see some of the yellow spots.

Thanks everyone!

With pastel albinos they normally have yellow blush spots down their spine. They also have brighter yellows and more contrast. A pastel albino will not look like a pale albino, if anything, its brighter.
