The term 'abnormally white' can be described as an albino, which is a six-letter word. An albino is a person or animal with a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair, and eyes. This condition is caused by a lack of melanin, which is the pigment that gives color to the skin, hair, and eyes. Albinism is a rare condition, and those affected by it often experience vision problems due to their lack of pigment.
