The colour of a person's eyes could give away key personality traits, according to a new study.
Researchers from the University of Queensland and the University of NSW analysed the eye colour of 336 Australians - most with a northern European background. They answered a series of questionnaires measuring aspects of their personality like agreeableness, conscientiousness and neuroticism.
Northern Europeans with lighter coloured eyes tended to be seen as less agreeable and more competitive. They were also more egocentric and skeptical of others, according to the paper published in Current Psychology.
Northern Europeans with darker eyes were seen as more altruistic, sympathetic and willing to help others, they found. Although the same correlation didn't arise with other Europeans.
Researchers believe the link has evolutionary roots, Medical Daily reported.
