just a thought or two
leucism is often mistaken for albinism, leucism can cause reduction in all types of pigment. Albinism results in the reduction of melanin production only, though melanophore is still present, so in species that have other pigment cell-types albinos can visually display a pale yellow colour.
Albinos display a red eye colour due to a lack of melanin production whereas leucistic animals have normally coloured eyes.
