Generally “patina” refers to the observable aging on surfaces with time, however, in design it especially refers to the colour (usually brown or green) and feel added to specific metallic surfaces during weathering. The most common metals in this vein are copper, bronze and steel. Patination happens either obviously, through exposure to the components over time (oxidization), or artificially, in factory conditions that hasten the procedure.

The Statue of Liberty is the most famous case of a patinated copper; its identifiable green colour covers every inch of the outside. Architectural applications have a tendency to be sculptural, but the green patina is still used for result.

What appears fairly even in the distance is in fact mottled up near. When materials like copper gain their patina obviously, the speed at which it happens will depend on orientation, climate and other aspects. A soffit, by way of instance, will take much more time to turn green than a roof or facade.

Patinated steel frequently goes by the name Cor-Ten; the substance is coated with a coating of rust through weathering. The application is a favorite in modern buildings and landscapes. One needs to take note that the rust may bleed onto adjoining surfaces, such as concrete sidewalks under a weathered steel wall.

Cor-Ten steel is rather uniform, but it still has variation (in colour and feel) that exhibits the process it underwent. A coating of rust might seem to be a bad thing, but it actually protects the steel underneath, and therefore requires little to no maintenance.
