The oxidation of copper turns the metal green. The green layer is often referred to as patina (comes from the Latin paten) or verdigris (comes from French for green gray).

It's called patina. It is the equivalent of red rust on iron. Copper oxide is the green stuff you see on old copper... copper rust... patina.
