what colour carpet for this sofa?

[NoNotYou]

Any thoughts?

The walls are F & B Skimming Stone

Im going for modern if that matters!

That's really tricky. Are there any mock ups on the website where you bought the couch? A wooden floor would look great but if you are keen on carpet very light grey or stone colour. So long as you bring in some accessories to match carpet it will look fine. Lovely couch by the way, nearly bought a gorgeous chair the same colour.
