Color can affect a person's behavior because it can change the way a person feels. It can affect mood, feelings and emotions, as studied in the field of color psychology. Many schools, businesses, hospitals and interior designers use the guidelines of color psychology to achieve a desired result.
Ancient societies, such as the Egyptians and Chinese, used color as a healing therapy. This therapy is used even today as an alternative treatment for different conditions. It uses the color red to stimulate the body and mind and to increase circulation. Yellow is used for cleansing and nerve stimulation. Orange is thought to help with lungs and energy levels. Blue is known as a relaxing color, and some use it to treat pain. Indigo is used to eliminate skin problems.
One of the most extreme cases where a color is used to change a behavior is at the San Bernardino County Probation Department in California. This institution uses a bubble-gum pink color to sooth and relax juveniles who are behaving violently. When violent juveniles are placed in a small cell colored in bubble gum pink, they are noted to relax, stop yelling and usually fall asleep quickly. However, according to Gruson of the New York Times, not all psychologists agree with the effectiveness of this method.
