Color and Physiology Color effects us physically. Different colors cause reactions in our bodies and minds. Interestingly both blind and sighted subjects were equally effected by color changes. Red is stimulating and blue calming. Bright red and yellow increase blood pressure and muscle tension.
People feel warmer in a red room and cooler in a blue room of the same temperature.
Blue rooms decrease blood pressure and lessen aggressive feelings. Studies have shown an increase in fertility in blue rooms. Orange is an appetite stimulant. Peaches brick and coral colors have a slightly less stimulating effect than bright orange. Brown also stimulates appetite especially when combined with peach or strawberry pink.
