Could this work?! They will be opposite each other. 1 is my pre-DH lovely mocha one. The carpet is green, and there are various green/blue/purples in fireplace tiles. Curtains are a peachy neutral (eugh yes I know we inherited the curtains!). Walls fairly neutral. Wondering if I can get away with a blue or purple sofa opposite then tie in the common colours with cushions iyswim?
