Different colours influence people differently. Red is an exciting colour. It creates an image（印象）of action, energy and danger. Red is often used in flags. 80%of the world's flags have red in them. A study in Germany showed that football teams wearing red are more successful.
Blue is a very calm colour. Businessmen usually wear dark blue suits. Blue is also a peaceful colour. The flag of the United Nations is light blue.
Yellow means freedom（自由）and green is a very relaxing colour. Some doctors nowadays wear green, because it's less tiring than white. White is a clean and strong colour. This is one reason why most doctors wear white coats. We believe in them more. People wearing grey do not want others to notice them. Brown is the opposite of black. It is warm and friendly.
