But then adult Nora has white and black hair. All the color has been washed out, which does fit with what we know about Nora's life post 1995. She's given up on her music dreams and is in an unhappy marriage with a women who hold's her back instead of lifting her up in the way Swann/Kat/the girl's friendship did.

I think Nora's hair is a metaphor for her joy and how comfortable she feels being herself. She starts the game happy and as herself, then becomes even happier and more confident as Swann and Kat become a part of her friend group. Then after the events of everything she's become a "washed out," version of herself who struggles in the aftermath of everything and has lost herself in adulthood.
