While it is known that people around the world associate colours with emotions, a recent study has found that from different parts of the world often associate the same colours with the same emotions.
The study was published in the journal 'Psychological Science' and was the result of a detailed survey of 4,598 participants from 30 nations over six continents, carried out by an international research team.
"No similar study of this scope has ever been carried out," said Dr Daniel Oberfeld-Twistel, member of the participating team at Johannes Gutenberg University Mainz (JGU). "It allowed us to obtain a comprehensive overview and establish that colour-emotion associations are surprisingly similar around the world."
Scientists report that the participants were asked to fill out an online questionnaire, which involved assigning up to 20 emotions to 12 different colour terms. The participants were also asked to specify the intensity with which they associated the colour term with the emotion. The researchers then calculated the national averages for the data and compared these with the worldwide average.
"This revealed a significant global consensus," summarised Oberfeld-Twistel. "For example, throughout the world, the colour of red is the only colour that is strongly associated with both a positive feeling - love - and a negative feeling - anger." Brown, on the other hand, triggers the fewest emotions globally.
However, the scientists also noted some national peculiarities. For example, the colour of white is much more closely associated with sadness in China than it is in other countries, and the same applies to purple in Greece.
"This may be because in China white clothing is worn at funerals and the colour dark purple is used in the Greek Orthodox Church during periods of mourning," explained Oberfeld-Twistel.
In addition to such cultural peculiarities, the climate may also play a role. According to the findings from another of the team's studies, yellow tends to be more closely associated with the emotion of joy in countries that see less sunshine, while the association is weaker in areas that have greater exposure to it.
According to Dr Daniel Oberfeld-Twistel, it is currently difficult to say exactly what the causes for global similarities and differences are. "There is a range of possible influencing factors: language, culture, religion, climate, the history of human development, the human perceptual system." Many fundamental questions about the mechanisms of colour-emotion associations have yet to be clarified, he continued.
However, by using an in-depth analysis that included the use of a machine learning approach developed by Oberfeld-Twistel, a computer program that improves itself as the database grows, the scientists have already discovered that the differences between individual nations are greater the more they are geographically separated and/or the greater the differences between the languages spoken in them.
