Visible light is composed of all the colors in the spectrum of visible light, those being red, orange, yellow, green, blue, violet, and indigo.  Those all combine together to produce white light.  Objects that are black, or appear black, will not reflect any of those wavelengths, they absorb them rather than reflect them.  This transfers to increased radiation absorption, which causes increased thermal reaction.  Objects that are lighter in color, or white, reflect most or all of those wavelengths and tend to have less radiation absorption, so they have less thermal reaction.
