Most intimidating color

They looked at last year's Euro 2004 soccer tournament in Portugal, and in particular at the five teams that wore two different colours, one of them red, in different games during the competition.Those teams tended to perform better when wearing red as opposed to their other colours, they claim.In four of these events (boxing, tae kwon do, Greco-Roman wrestling and freestyle wrestling) combatants are randomly assigned either blue or red outfits.Those wearing red won 55% of all competitions, report Russell Hill and Robert Barton of the University of Durham, UK.This has led to some strange effects in studies of animal behaviour, says Hill: some male birds given brightly-coloured leg bands for identification in long-term experiments have found themselves catapulted to the top of the mating ranks, he says.In human societies, red's aggressive, winning quality may explain why many military uniforms and medals feature the colour, comments Andrew Walton, a sports psychologist based in Coventry, UK.

Your go-to colors: Neutral colors that fall in the middle of the color spectrum.
