Answer:
The darker the object, the better it emits heat, because it's a better absorber of light. On the other hand, a white object appears white because it reflects all the different wavelengths and absorbs little to no light. It doesn't absorb much energy, then, and puts off little to no heat. Light energy can be converted into heat energy. A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. A white object reflects all wavelengths of light, so the light is not converted into heat and the temperature of the object does not increase noticeably.
Explanation:
A dark object of a given color will absorb more photons than a light object of the same color, so it will absorb more heat and get warmer.
