"Caramel Albino" is a name dubbed a certain shade of Amelanistic (lacking melanin, black).
The strain of colors of the original snakes the amelanistics came from were a certain shade so that when the black was removed the yellows and reds etc left where a "caramel" color.
So someone gave this strain of amelanistic the saleable name "Caramel Albino".
Scott uses the name for some of his amelanistic easterns.
