Copper will darken and get a greenish tinge eventually. Most inorganic compounds of copper are green. The plating process may require the frame to be plated first with nickel, then with copper. But I'm not an expert in plating.

Does anyone know any (USA) vendors and/or any information about copper plating, like how destructive the plating process is to steel frames? It looks like an optimum finish in several ways, but have only seen one bike to date, so don't know why there aren't more.
Thinking about leaving front and rear forks standard Raleigh chrome plated to reduce additional metallurgical processes done to those frame components, and just buff frame down and clear coat.
Thanks,
