Here is a picture of one of my 9 month old crested gecko. I have noticed that she tend to have a lighter colored back compared to her sides. When younger she was mostly a uniform reddish yellow, sometimes more yellow other times darker.
Being far from an export about pattern/color morphs, I figured I will post it here and see what the more experienced breeders have to say. The parents didn't seem to exhibit this characteristic, from what I can remember. (I saw the parents when I bought the crested but don't remember if they looked like this, though both were reddish).
