Pastels start out as yellow but many tend to brown out over age. look at the top of the alien head pattern. it's no longer a vibrant yellow but it's becoming increasingly dull or speckled brown. some hold their yellows better, some turn brown, some turn into something in between. it's up to u if u wanna purchase her. we always tell peeps to buy and work w/ what they like but it is also recommended to try to breed the best genes/looking snakes. just remember, if u breed u have to be responsible as all the babies will need homes.
