Does copper migrate through silver?


Today I removed my ACME silver plated cryo receptacle from more than 20 days' burn in through my refrigerator. I noticed the silver was more 'orange' in color, as if copper had mixed with it. Is this possible or just an optical illusion?

I have also seen silver oxidize heavily at room temperature. It can be polished back to shiny though.
