Pastel Vanilla Fire as an Adult?

Hello!

I've been looking at ball pythons, as I plan to possibly buy next week, and I came across this beautiful lady: https://www.morphmarket.com/us/c/reptiles/pythons/ball-pythons/297459
I wanted to know how much her color is going to change as she gets older? I've heard pastels tend to brown out and I can't find any good pictures of adult ball pythons with this gene combination.
Also, which genes tend to retain color or lighten up as they get older?

Thank you.

Thats a nice looking girl! Both vanilla and fire are brightening genes, so that combination shouldn't brown out much at all with the pastel added.
Here are some examples of the vanilla scream (fire vanilla pastel)

This one has super pastel in it instead, I would get this one instead of the vanilla fire pastel, it should stay really bright!
