    Re: High Contrast Albino Question

    Do you see a lot of albinos whose white isn't bright? The white in faded albinos is just as bright as the white in normal and high contrast albinos. The contrast comes from the yellow. The deeper the yellow, the more contrast the animal has. Again, Cinnies and black pastels are very dark, having increased melanin, but they also have some what hyper xanthic pigment behind all that black. That is what gives the combos are high contrast, not becasuse of the darker blacks. Increased xanthism in albinos = high contrast. hypo xanthism in albinos = faded albinos. That's why the most faded albino that exists is the snow, an albino that is also an axanthic. That is why peds, which have very hyper xanthis edges around the brown areas makes such high contrast albinos. Albino pied have deep yellows and even oranges, because of the increased xanthism that is in piebalds to begin with. Cinny albinos and black pasel albinos also look more high contrast because of the amount of black only areas. They both make albinos that have larger areas of white, which when combined with the increased concentration of xanthiphore in the smaller yellow areas, adds to the higher contrast appearance. But that has to do with surface area and white:yellow ratios, not the degree of melanin an animal has in the dark areas.

    Check it out for yourselves. The white in every albino is the same bright shade of white, for the most part. The melanin/black pigment/white areas in albinos, has nothing to do with the contrast of the albino's appearance.
