What eye color is the primary feature differentiating white tigers (leucism) from true albinos?

Bright, piercing blue eyes

The eye color serves as a critical diagnostic tool to separate individuals displaying leucism from those exhibiting true albinism. True albinism involves a total absence of pigment across the board, which leaves the blood vessels in the iris visible, often resulting in pink or reddish eyes. In contrast, white tigers carry the genetic condition of leucism, which reduces overall pigmentation but does not eliminate it entirely. This reduced pigmentation allows for the characteristic bright, piercing blue eyes, which is the hallmark feature used to distinguish them from albinos. While rare instances of amber or green eyes might occur in tigers carrying the white gene, blue is overwhelmingly the standard identifying trait differentiating them from the pink-eyed albino condition.
