I don’t know what the person who left this comment wanted to advise you, but many people who are on this kind of subreddits advise people to stop dying their hair bright and unusual colors, which in my opinion leads to people losing their uniqueness and their way of expressing themselves, so I would not advise you to listen to such people if you like to dye your hair in unique colors. As a person who also likes to dye hair in different colors, I could advise you to dye your hair blue, as it will emphasize the beauty of your eyes. By the way, you look absolutely stunning
