A person, whether negro, Indian, or white, in whom by some
   defect of organization the substance which gives color to the skin,
   hair, and eyes is deficient or in a morbid state. An albino has a skin
   of a milky hue, with hair of the same color, and eyes with deep red
   pupil and pink or blue iris. The term is also used of the lower
   animals, as white mice, elephants, etc.; and of plants in a whitish
   condition from the absence of chlorophyll.
