Several studies have indicated that red carries the strongest reaction of all the colors. Red is hot. It's a strong color that conjures up a range of seemingly conflicting emotions from passionate love to violence and warfare. Red is Cupid and the Devil.
A stimulant, red is the hottest of the warm colors, which can have a physical effect, increasing the rate of respiration and raising blood pressure. Red is used as a symbol of guilt, sin and anger, often as connected with blood or sex. It is associated with lust, passion, love, and beauty as well.
So would you paint your room red? :)
