When copper is oxidized by a combination of air, humid and finely divided acid and salts in the air, then a so-called patina of copper is formed. This is a basic copper (II) carbonate/sulfate mix, which has a cyan color. The reason that the color changes is that a chemical compound of copper is formed. Copper itself is a metallic element. Compounds of elements can have totally different properties than the elements themselves (e.g. look at hydrogen and oxygen, these are gasses at room temperature, while the compound water, made of both elements is a liquid at room temperature). A similar thing you see with iron.
