Have you ever wondered why you often feel cosier in the presence of red? Like other richly pigmented tones, red also absorbs light. This tricks the mind into believing the room is smaller and cosier than it actually is, and often assists in raising people’s perceptions of a room’s temperature. In fact, in some experiments, people estimated the temperature in a room painted red as being six degrees centigrade higher than in a blue room. On one hand where it is the color which radiates warmth on the other it is the color of love and passion.
So, if you want to lower your energy bills, why don’t you try painting the north-facing rooms and other cool spaces in your house a warm red? It just might persuade your whole family not to turn up the heating.
