If so, what color?

We didn't, because we have weird high walls/ceilings, and we rent. We are allowed to paint, but we're not planning on staying here long and didn't want to have to turn around and repaint.

So instead of paint to bring some color in I put circle decals on one wall (in grey, yellow and teal), and a big tapestry on another.

I like the warmness they bring to the room but can't wait until we are in a more permanent place where I can paint!
