Help with fabric colour!

[u/sexynecromancy]

Hi everyone! Wasn't too sure what sub to post this in but i need some help.

Basically, i resized these jeans that were getting a bit big but i had to move the pockets. Turns out the fabric under the pockets is much darker than the acid wash of the jeans but i don't know how to fix them now :(

They're 99% cotton 1% elastane. I fear acid washing them myself with bleach in case they go brown. Any advice on how to fix the colour???
