Other studies have looked at how colors influence decisions.
Soccer referees made more decisions against teams that wore black uniforms. Tae kwon do referees gave competitors in red. In another study, students who saw the color red before a test did much more poorly. Of course, these test results might vary from culture to culture.
Most people do not realize how much color affects them. It can affect how people think, feel, and act. Some colors such as those in nature can have the same meaning for everyone. Other colors meaning may be different in different culture. We can increase our understanding of ourselves and the world around us by learning about what colors can mean or represent.
