Caramel Albino / T+ Albino

Recessive

Caramel Albino is a recessive color morph in Dumeril’s boas that greatly reduces dark pigment, turning the snake’s usual brown-and-black look into warm cream/yellow/tan “caramel” tones with a softer, lower-contrast pattern (often with lighter eyes and possible mild light sensitivity).
