Everyone has a favourite colour. We tend to stick with just one colour throughout our lives. A new study has found that the most common favourite colour is blue. The BBC in the U.K. looked at how and why people like one colour more than another. There were two main findings in the research. One was that a majority of people around the world like the colour blue most. The other finding was that people change the colours they like as they get older. The researchers said our experiences in life change the way we feel about colour. In particular, people often like darker colours as they get older. The studies showed that dark yellowish-brown was the world's least liked colour.
The BBC looked into studies from two universities in the USA. They said blue has been a favourite since research began on colour in the 1800s. The researchers said most people's experiences of blue are positive. Many colours in nature that we love are blue, especially a blue sky, the sea and many flowers. A blue sky is enough to make many people very happy. The researchers say one of the only negative associations with blue was in the English language. In English, people say they "have the blues" or are "feeling blue," meaning they are sad. One factor in choosing a favourite colour was a sports team. Many people like the colour the team they support plays in.
