Original color of copper is brown. When it exposed to the air, it will oxidized and form copper(II) ion. The reaction of copper(ii) ion with water from air produces copper (II) hydroxide and normally its color is blue or greenish. So if you want the name of reaction, it is corrosion of metal or oxidation.
