It'll probably work just fine. I used chipit on the living room photo with the couch in it and it's reading the wall color as Folkstone, which looks pretty close to Anonymous.
I love warm grays - I'm sure it'll look great. The other nice thing about that couch is that it's microfiber which I find to be pretty stain/animal/husband resistant. We got microsuede ones at Raymour and Flannigan a few years ago and they still look good =)
