What would be some good colors to go with sage green couch?
You could pick out the red or green in your rug. My furniture has sage green microsuede and a reddish colored wood for the arms-Mission style. Kind of like a Morris chair. Most of my accessories run in the deep purple and beige depending on the season. My floor tile is a peachy sand color and my accent rug is a mixture of reds, greens, black, with a tiny hint of light lavender. It sounds very eclectic, but it all fits together pretty good. As far as curtains go, your furnishings sound a bit contemporary. You could go neutral, But I think I would use something with alot of colors in it? That would bring out the colors of your rugs. Nothing ruffly, but tailored, perhaps in a stripe. Hope this helps give you ideas. Have fun and experiment!
