It just tarnishes to a dark reddish brown over time. Unless you leave it out in the elements like the statue of liberty I guess. If you've ever seen old copper cookware it's like that.
Also, sweet sweet thermal conductivity.
It's also antibacterial
It's worth noting on that pot that the inside has been exposed to things like salts and acids that the outside has not. In a similar vein, those who are forcing a patina use different salts/acids depending on what they are shooting for.
Lots of copper cookware is also tin plated on the inside to prevent copper leeching.
