Have you ever been so sad you felt blue, or so jealous you turned green with envy? Your answers may depend on where you live. Psychologists recently asked 711 people from China, Germany, Greece, and the United Kingdom what emotions different colors brought to mind. They found that participants’ answers varied depending on what country they were from. In Germany and the U.K., for example, yellow was most associated with joy. But people in China paired this feeling with red—a traditional symbol of happiness in their culture. Similarly, people from Greece associated purple with sadness, while those in other places considered it more positively. After discovering these color connections, the scientists used them to predict where a person was from; they were correct more than 80 percent of the time. Next, scientists hope to expand this research to less industrialized nations to see how the results might change.
