Looking for something-

I read something a few months ago and I'm hoping to find it again. I believe it's a isekai with a female protag (or at least set in that sort of time line). The only thing I really remember is one specific part, she's about to go to a party and a bunch of women are gossiping about her hair color (either red or pinkish) and that having that hair color is ugly, but when she shows up, she's styled in such a way that everything thinks it looks good. Help would be appreciated!
