Psychologists have found that color can influence how we feel and can even cause physiological changes in our body. Keep in mind, however, that there are different interpretations of color’s impact on emotions depending on culture and circumstance.

Research shows that certain colors can increase blood pressure, metabolism, and adrenaline. Other studies have found that certain colors can improve sleep habits, boost memory, and enhance academic performance. One study discovered that seeing the color red before taking a test can hurt performance. Students who were shown a red number before taking the test scored more than 20 percent lower than those shown a green or black number.

Just as color influences our mood, it can also be used to describe how we feel. A study reported in the journal BMC Medical Research indicated that people with depression or anxiety were more likely to associate their mood with the color gray, while happier people preferred yellow.

Researchers at the University of California determined that young children chose bright colors to represent positive feelings and dark colors for negative feelings. They were even able to identify how specific colors made the children feel: red is for mad, blue is for sad, yellow is for happy, and green is for glad. Color can therefore be a very helpful tool in accessing children’s emotions instead of relying on them to tell us how they feel.

Institutions like the American Red Cross, St. Jude's Hospital, Boston Children's Hospital, and Scholastic incorporate this ability to connect feelings to colors as a way to better understand the emotions of young children. So if our children tell us they feel gray or blue, are seeing red, or feel green with envy, we will know what they are talking about can guide them through their emotions
