Why don't we see more people wearing red?

I own one red shirt (The 'Communist Party' shirt, which is great) and only wear it rarely. But I have a theory as to why it isn't a more common color to be worn. I would venture to believe that red clothing in sports is ok, but if you wear it in normal life you are more likely to be seen as brash and wild.

I know that the few people I know that wear red will actually wear a whole slew of ugly colors (lime green, neon purple) and not just that one color. Also, I must wonder about the surge of pink clothing we are seeing in American business.

i started wearing red as a result of hearing of results like these years ago. can't tell if it has had an impact with one data point, it is eye grabbing though.

Why don't we see many more people wearing red?

I was told when I was younger that red didn't look good on me because of my pink Irish skin.

Can the rest of the color spectrum be ranked similarly in its effect on referees' evaluations?

Not a lot of evidence here. Some psychologists briefly thought blue had an advantage over white in judo matches but it turned out that combatants in blue were higher seeds and thus were expected to perform better. Black seems to have some similar effects of red but I don't think they've ever been paired head-to-head.

Yellow got it's ass kicked in English football. Other than that I don't know.
