how long should she have her gravid colors?

[Pirranha]

so as i posted a little lower-my veiled just had her first clutch.
Its been a few days now and i was wondering how long it will be before she gets her normal green colors back and not the dark background with blue spots and yellow stripes?
Im curious to know if she might have retained sperm and thats why she hasnt got her normal colors back yet.Or if she could have kept a few eggs inside her even.
or if it just takes awhile for her to get back to her normal self.
she didnt look too thin after laying and is looking really chubby already,its not from too much food.
