Like Albino Axolotls, Leucistic Axolotls are also white. The main difference is Leucistics always have black eyes, unlike the red eyes of Albinos. Occasionally Leucistics will have black spots, too.
Just like the Leucistics, Albinos are white. They have no pigment in their skin or eyes, so their eyes appear red/pink in colour. True Albinos have no color except white and red/pink.
In addition to the common white Albino, there are Golden Albino Axolotls. These appear a peachy yellow color and have gills that are generally the same color (not bright red like the white Albinos, although this can also sometimes be found).
