Dull dark objects absorb more light and heat energy than bright shiny objects, which reflect more light. The absorbed light energy is then converted into heat, causing dull dark objects to emit more heat. Bright shiny objects reflect a greater portion of incoming light, so less energy is absorbed and emitted as heat.
