Yes that is very true, but in order for his to go to violet or red even with being an albino or recessive gene he would have to lack the OCA2 greatly, he couldn't have AA and most likely not AG. Since violet and red travel in the blue genes, he would have to have GG gene, which is most common in Europeans, so he would most likely have to be European. There also has been studies showing that 'Red' eyes are actually brown, but the Red looking brown eye aren't found in albinos, so that could be a possiblity, but they would be slightly more brown than red and would't really change color. Violet is sometimes lighting of the color brown or blue. Yes, having the Red or Violet eyes would be all about the genes in the parents and what alleles are dominant, Brown, Blue, or Grey(green). Now, each person has 46 chromosomes, Red and Violet eyes often lack or have extra. So you would have to take into account how many he has, Often albinos lack and have 38 or less. Being that he isn't, in order to have Violet eyes the Brown allese would be dominant, taking up 23+ of the chromosomes, now where are the other 23 from? That plays a big part in it, if there is more blue than green, you on the very rare chance could have Red eyes, now the Brown allese would have to be lesser, and Blue slightly greater than Green, but Green more dominant that brown, that could make Violet eyes.
Now to get out of the confussing stuff, to have Red eyes and them change, it would be slightly only a tint, but the main color would have to be brown. Violet eyes, they would have to be blue or an odd green and only change slightly. Large changes in eye color have never been heard of. Now you going to think, 'but your eyes go from brown to green' my eyes are Hazel, which is already a mix of Brown and Green, the Brown and Green allese were very close and blue was barely there. So really it is up to picking his genes, which I would save on a sticky note for later RPs. To make is easier I have him as an albino with a spray tan and died hair -laughs silently- or you could pick between Red and Violet, pick a base color, sort out genes, and write it all down. No I will not become a scientist.}
