Colourful or neutral/maximalism or not

I’ve been curious because I see other audhd or just adhd or autism people surrounding themselves with a lot of very strong colors or for example covering all surfaces with things they’re into with like posters or dolls or other things.

I’m not a tidy person and definitely not a minimalist or opposed to colours but I get so anxious if things are visually busy. I can’t relax in lots of strong colours or things around me and I’m wondering if these are equally common or what side sort of causes it. What’s your preference and why?
