I called SIG and was asked to send pictures. So I did, and 30 minutes later i got a response.
Jay at SIG customer service says "A dye is introduced into the hard coat during the anodizing process. As the hard coat (and subsequently the dye)wears, a little discoloration can occur. Most of the time it’s the bronze color seen, but sometimes it lightens the dye, so it looks purple. Nothing to worry about."
I'll accept that.
Sent from my phone...expect typos.
