When 50 male and 50 female volunteers were shown images of men in different coloured t-shirts, they rated those wearing red as more aggressive and angry than those in blue or grey.
However, while the male volunteers also tended to consider men wearing red as 'dominant', the female volunteers did not.
The results of the research may have parallels in nature and could provide insights into whether it is advisable to wear red in certain social situations, said Rob Barton, Professor in Evolutionary Anthropology at Durham University, who led the study.
Red often signals aggression in animals - and the tendency for men to turn red-faced when they are angry is believed to be inherited from our ancient ancestors as a warning sign. In some animal species, red may be displayed by competing males trying to dominate each other to win the right to mate with females, he said.
Ms Wiedemann, who conducted the experiments, said: "We know that the colour red has an effect on the human brain. This is embedded in our culture, for example the idea of wearing a red tie – known as a 'power tie' - for business, or issuing a red alert."
"The implications of our research are that people may wish to think carefully about wearing red in social situations and perhaps important meetings, such as job interviews. Being perceived as aggressive or dominant may be an advantage in some circumstances but a disadvantage in others, for example where teamwork or trustworthiness is important."
Durham University researchers have previously shown that wearing red can have effects in sport, promoting aggression and competitiveness within teams and intimidating opponents. Professor Barton and his team are currently talking to organisers of combat sports about the possibility of introducing new rules on competitors wearing red, to avoid the colour being used to unfair advantage.
