I am not sure. Shayna, my BP, faded a little with age, but not too much. I know it can happen with BP's, but I don't know how that works with Carpets. So far, he definitely isn't fading. He's still super bright and yellow. He lost most of the orange/peach tones he had on his body and face and neck, although there is still a little around his face and neck. I imagine breeding has something to do with it as well. I've seen Darwin Albino carpets who are young and to nearly as bright as Yafe. I am not sure if the IJ cross helps the yellows be more intense or not, as they are not too common that I've seen (IJ/Darwin Hybrids). I do not believe there is an IJ albino that's been found, and that's one of the reasons they cross them with Darwins.
I hope he stays bright and intense, but will love him the same either way.
