I guess I never had a 'normie' style but since I've started to wear mostly bright, pastel or at least light colours people are actually nicer and more interested.

I haven't found any negative side effects other than the lost feeling when I accidently wear grey and the world somehow feels different.

I mean, there's always a dominant fashion trend (_particularly_ in interior decoration; you can really date this to within a few years in many cases), and there are always people who don't conform to it. This isn't new and hasn't changed.
