In a 2010 cross-cultural study involving participants from China, England, Germany, and the US, it was discovered that women have a greater attraction to men wearing red. In one experiment, 55 female undergraduates viewed a color photo of a man donning either a red or green shirt and subsequently rated the man’s attractiveness. Notably, the man received significantly higher attractiveness ratings when he was depicted wearing a red shirt. Similar results were observed when comparing the red shirt to shirts of other colors. Interestingly, participants were generally unaware that the color of the man’s clothing was influencing their perception of his attractiveness.
