Betta Fish: Yellow (gold maybe?)

I generally do not buy fish from the box stores, but I was there to browse a couple items to see them in person before ordering elsewhere and saw this betta. Maybe it's super common, but I don't feel like I have seen yellow (maybe a gold of some sort) often, if at all. Especially in a female betta. Maybe she's more common than I think, but it peaked my interest enough that I bought her. About to go into a 20 long by herself. Do you see yellow very often?
