Albinism is a lack of melanin therefore you're left with white unless there are other pigments involved. What is black is white on the albino unless the melanin was masking another colour (which appears to be what the black blue tongues are).
yeah I am a little confused.... can you explain why a albino murray daling carpet is bright orange where it normally is black and yellow where the silver usually is? and if the black was ''masking'' the background colour then wouldn't it be solid yellow? In blue tongues if the black is just masking other colours and you are saying it will not be produced because albinos cant produce melanin. wouldn't the double homozygous form of the just look like a normal albino and not solid orange?
