Many people are aware that color can have an affect on mood, but research also has determined that seeing certain colors can affect mental processes. In fact, people who see the color red are likely to do more poorly on a test or exam. Some studies indicate that cooler colors, such as blue or green, tend to promote concentration and increase creativity and other cognitive skills.
More facts about color and performance:
-Not all studies agree regarding the effects of red on test scores. One school of thought holds that in cultures where red is perceived to be a sign of danger, the potential for breaking concentration and leading to lower test scores is greater.
-Different studies exploring the connection between color and performance have used different criteria. Some studies have focused only on the reaction to specific hues, and other research has considered additional elements such as brightness and saturation.
-In addition to test scores, research into the connection between color and performance has involved tasks such as changes in comprehension levels while reading and in performing simple tasks such as arranging a collection of files in alphabetical order.
