No, it's a reference to the patina copper gets over time, starting out the orangey brown color, eventually gaining a green tarnish. You can't always take the descriptions as something literally in the game.

The Rust dragon does have a similar pattern because it's meant to represent a similar process, oxidation of metals through exposure to the elements.
