which colour is best at absorbing heat
Dark Colors. Dark colors absorb a lot more heat than lighter ones because they absorb more light energy. In fact, the closer to black a color is, the more heat it absorbs from light sources. The key is that colors do not absorb different amounts of heat, only heat from light. Dark and light colored clothes coming out of a dryer will be the same temperature. However, because light clothes reflect more light when a person is outside, the accompanying heat from the sun is reflected as well.
