In the summer air-conditioners work all the time to try and keep interiors cool. Most roofs are made of dark shingles, making it even harder on the air-conditioner. Through studies it has been shown that roofs that are white or reflective do a much better job of reducing the amount of heat that is absorbed into the house. This is because the color white reflects light whereas black absorbs the light and the heat that comes with it. By reflecting the light, energy bills are reduced because the air does not have to work as hard to keep the house cool.
When trying to reduce energy prices inside a house the same principle exists. Lighter colored walls will reflect more of the artificial light used. This allows a lower wattage of light bulb to be used, decreasing the energy used. It has been proven that "white reflects 80% of the light, black 5% (Morton)." The color used can also affect the temperature people perceive in the room.
