Explanation: 

Detailed explanation-1: -Dark surfaces absorb more insolation than light surfaces. As a result they heat up faster. This should be another familiar sensation to anyone who has made the bad decision to wear a black tee shirt on a hot summer day. Light colors reflect more insolation than dark surfaces.

Detailed explanation-2: -Darker-colored objects absorb more visible radiation, whereas lighter-colored objects reflect more visible radiation.

Detailed explanation-3: -An asphalt surface absorbs more solar energy than a cement surface. This difference is chiefly due to differences in color. How does global warming alter the albedo of the Arctic?

Detailed explanation-4: -This tells us that a dull, black surface is a better absorber of radiation than a shiny, polished surface. Dark matt surfaces are better at absorbing heat energy than light shiny surfaces.
