Perhaps shades of cream and blue in a contemporary design.

This is the easiest question I have seen on Houzz. I can think of several on Ballard Designs. If that is not your price point. JC Penny has good selection. Pop of color is not needed what is needed is texture, bold pattern in blue tan combo of the room. Look for large scale design.

Forgot to say nice room.

I would keep it neutral with a sisal rug;) I think the art in this picture could work too!

Thanks for the ideas...they are all great and Margo I am working on an original piece of art for the wall :)
