Supposedly the color pink is supposed to reduce overall athletic performance. I had a speech/psych teacher who was talking about the effects of different colors (mostly red) on neurochemicals as well as other noticeable physiological changes. He said that lifters who looked at the color pink whlie lifting could not lift as much as they could when they were looking at other colors/nothing.
I thought it was interesting, I have no idea if it's actually true. Maybe pink trunks would give a fighter an extra edge
