I have what I believe to be a normal female, however each time she sheds she becomes more yellow to the point where she is a more true yellow color than her pastel brother. When I first got her she was a normal brown color.
She is from a pastelXmojave cross. I am just curious and would appreciate some feed back and comments on why this maybe happening.

P.S- She is perfectly healthy, kept at all the right temps and humidity and has been checked by a vet because I was worried about the yellow color and her blood work was great. She's 200 grams so she can’t be glowing yet I think she would be to immature for that.
There are pics in my profile but not recent, I will try to post some later.
