This is absolutely a first world problem, but I know some people on here have a better eye for this kind of stuff than I do, so if you feel like looking, I could use some advice.

We finally got a new duvet that DH and I both like, but we aren't in love with the way it looks in our room. We got this duvet from West Elm for Christmas: http://bit.ly/1lPwAwx

It's a light, cool, gray and white. Our walls are a light blue, almost sky blue but a bit lighter. Headboard and other furniture are dark wood.

We feel like the duvet and walls are too close in tone and too cool, so I'd like to add in something to either warm it up a little or just to add a little pop. Any advice? I was thinking colored sheets or throw blanket (we aren't really into extra throw pillows on the bed since they end up on the floor, which would turn them into dog beds!). What color do you think would add some warmth and pop?
