WebThe reason a dark object like an asphalt road gets hot quickly is that colors like black absorb most wavelengths of light, and therefore absorb more energy in the form of thermal energy. In the same way, the melanin in your skin absorbs the UV from the sunlight because it is so dark, and protects your skin from it. WebColored objects, on the other hand, reflect back only some of the wavelengths; the rest they absorb. For example, if white light shines on a red ball, the ball reflects back mostly red light, and so we see red. Most of the greens and blues that are part of white light are absorbed by the ball so we cannot see them.
