Someone never having seen copper corrosion got me fucked up. It's definitely corroded copper, the "rose gold plating" is trash.
Not really an easy fix for it, you could clean all your keys really well and seal with clear epoxy or just embrace the new aesthetic. Oxidation like that is self-sealing, it'll stop once the whole surface is covered and imo looks pretty neat once you brush it smooth
