1. Antauri’s secondary color literally is purple, as in he is a carrier for the purple fur gene. I once tried to make a whole dominant-recessive table with all the team colors (I had to do something with all that high school-level genetics I learned) but for now I just have that black fur is dominate to purple fur, but Antauri still a carrier of it. I also like to think that it was his mother he inherited it from, so just image purple Antauri momma monkey :3
2. And speaking of carriers, Sprx is a carrier for albinism. This started as a joke as to why his red fur is so pinkish until I learned that albinism doesn’t work that way (it seems to be all or none like all other recessive traits, and a ‘partial albino’ can not exist) but I kept it because how how horrified he would be by the knowledge. Albinism doesn't just cause white fur, the characteristic red eyes result in damage to retinas, which in turn means issues with focus and depths perception. It’s not blindness, but it would be enough for Sprx who is already worried enough about his eyesight; knowing that he was basically one gene away from this would mortify him, despite the reassurance that the optical orbs would probably be able to counteract it.
