Is color an intrinsic property of a substance? I thought that if a red object is in an enclosed space, so that no light gets in, will no longer be red - and what makes the object "red" is that electrons absorb all colors of light and then reemit (reflect) the red light. Therefore, if no light reaches the object, it has no color - but I am probably wrong. This brings to mind another question or a possible conflicting scenario. A black object is a good absorber of radiation and an object that is white is a poor absorber of radiation. So, if I put a black coffee mug and a white coffee mug in a room that has no light, and the room is heated with infrared radiation, will the black mug absorb more thermal radiation? Does color ever come into play? Can someone please unravel my confusion?
