And people ranked how closely they linked them to the following emotions: anger, interest, amusement, pride, joy, pleasure, contentment, admiration, love, relief, compassion, sadness, guilt, regret, shame, disappointment, fear, disgust, contempt or hate.
The researchers, led by Johannes Gutenber University's Dr Daniel Oberfeld, wrote: 'Red is associated with both positive and negative emotions while black is unambiguously associated with negative emotions.
'In the current study, red was often associated with love and anger, while black was associated with sadness, hate and fear among other negative emotions.'
Other colors which had strong associations across countries were pink with love, grey with disappointment or sadness and orange with joy or pleasure.
Some other colors, however, had more nuanced associations.
For example, people in Greece were far more likely to associate turquoise with relief and purple with sadness than those in other countries.
While people in the UK and Germany strongly associated yellow with joy, but Greek and Chinese people did not feel the same link.
Almost all the colors, even if they didn't have a solid link to one emotion, were either overwhelmingly good or bad – with the exception of red, which was linked to both anger and love, and purple and brown, which were neither.
