Betta Fish Losing Color, Only Symptom

[DIscoMagician]

Hey, i'm back. I've fixed the water in my tank but my betta is rapidly losing color. all her behavior is good though. she explores the tank, eats immediately, got used to the filter moving water around, and her fins are wide open. She is losing color very quickly though and i don't know what I can do to help. Is that even a bad thing though? Is lose of color okay?

It would help to see a picture of before the color loss and presently with the color loss to see if there is anything that seems to be a concern.  Bettas are known for dramatic color changes so it might just be that but without a pic it would be hard to be sure.
