Thanks for your response Paul. The retina in on the back inside of the eye, it's the iris that sometimes has colors like brown green blue etc. The pupil is always black because essentially it's just an aperture or hole. With leucistics there is no brown green etc, just blue and black. Lack of pigment sometimes translates into blue too not just red in irises, like in blue eyed albinos. Blue is sometimes surrounded by a circle of red and the pupil itself can appear red if the light is just right.

The dominant white (blue eyed) cat is an interesting case isn't it? Imagine leucisticism as a dominant trait! : ) I thought for a while these cats were leucistic too, then I read they are dominant whites, so it is just maybe hard for me now to wrap my brain around them being dominant leucistic. : )

Likewise when I first saw the 'albino' or white dobermans with blue eyes, I thought there a case of leucistics alright, then I found out they do have a soft sort of light ceamy pigment like siberian huskies do in their white parts, that is almost never evident except when they are sitting in fresh white snow. So I guess they must be blue eyed albinos. Thanks for discussing this with me, I find albinism and leucisticism very interesting.
