Mirror mirror on the wall...

I have been shopping for a large mirror to go over the big empty wall over our couch. Unfortunately, mirrors are expensive and you rarely see coupons for them. A couple months ago the Sissine family was yard sale-ing and I came across this gold mirror. The lady wanted $50 for it and I politely declined. A few hours later we went back and the mirror was still there. I offered her $20. She said "$20?! But its a real mirror!". The first thing I thought was "As opposed to a fake mirror?". I didn't say that to her of course =) I just stood there and looked at her. She finally accepted my offer and we stuffed it in the Prius!! So now that I finally have it hanging, I am contemplating painting it black or not. Any opinions? Paint it or keep it gold? Here are a couple pictures of it:
