Do you have any other pics of that female, like when she was younger? I feel like a citrus pastel desert would be a lot brighter than that. Shooting from the hip, i'm gunna say it doesn't look like the desert gene is in that snake, and that's why she laid a viable clutch... This isn't something to joke around about either, not that anyone has been, because if that snake really doesn't carry the desert gene then people need to know. Otherwise you'll have everyone and their brother attempting to breed desert females and then killing their snakes.
Just my take on it, please don't take offense.
