city life is stressful - maybe people want to protect themselves with dark colors or perhaps it reflects their mood?
also it depends on what the market/brands are producing, and most of them are making dark colors.
the conspiracy level is maybe the dark colors are good for causing bad mood, more distance between people thus more sickness, easier to control, and more profit for the hospital? 👀
This sparked my curiosity, is there any study on this? :) I think it has more to do with each person's mood, but... It would be a hit on the ~charts territory :)
