Have you ever thought about the effects of colors on human psychology? According to studies, scientists claim that colors directly affect the parts of the brain that are responsible for emotional stimulation.When the eyes focus on a color, the body discharges various hormones that affect humans physically and emotionally. Senior psychologist Ayben Ertem who studies colors and psychology said, "The way we use and combine colors in our living space affects our living quality correspondingly with the inducements of colors in our brain." She pointed out the soothing and relaxing effect of pink, adding that color therapy is used at some prisons and psychiatric hospitals in U.S. where the walls are painted pink to calm violent criminals and psychiatric patients. She said using pink and purple in the bedrooms is a good idea, and stated, "Pink and purple are calming colors that discharge energy.When you use these colors in bedrooms, they will help you fall asleep easier." On the other hand, Ertem informed that red and orange increase appetite and encourage eating fast. "However, orange can be used, though not excessively, in dining rooms and kitchens since it leads to deep conversations," Ertem said. She also mentioned studies about the color blue. According to research, blue is an appetite suppressant that also decreases the pulse; hence, it can be used in the kitchens of people who that have weight problems. Ertem added that overweight people can hang blue magnets on the fridge to keep them away from it. She recommends not using yellow in kids' rooms saying, "According to the studies, it is determined that when yellow is used in babies' rooms those babies tend to cry more. Using red, blue and yellow harmoniously together is ideal for a boy's room. On the other hand, green, lilac, light blue and light yellow are feminine, calming but lively at the same time for the girls." Ertem further noted that red should not be used heavily in places where children with hyperactivity disorder spend time since it has a stimulating effect.
