Why are black colors the best absorber of light/heat?
Question Date: 2013-06-05
Answer 1:

Black color absorbs the most light and reflects the least light, and white color reflects the most light so it absorbs the least. When we talk about what we see we are actually talking about reflection, the opposite of absorption. When light shines on an object, the object’s color either absorbs or reflects the light. The color of an object depends on the light radiated back to our eyes. Green color, for instance, absorbs every color, except for green, which reflects back to our eyes. When white light hits a black object, the object absorbs all of the wavelengths, and none are reflected back. This is the reason why the object appears black to us.

Light is a form of energy, so when black colors are absorbing light, they are absorbing energy, too.
