Budget $50, $500, $5000 per chair?

I think a rich cream color would look very nice with the rest of the room. I am thinking something very much as the pillows in the left of your photo appear. Then if you're not totally wed to the mirror above the fireplace you can bring in artwork and some candles to pick up the cream of the chair. I assume the recliner you mentioned is in the upper right hand side (where for some reason another commenter moved a television into place.). A pillow or small throw placed on the chair can correlate to the rich cognac color of your sofa and love seat. Good luck.

I see the sofa as Art Deco influenced. This chair is a modern take and you can find it in lots of colors.
