What about a darker tan color for the bottom?

If you were my client I'd suggest one color on the wall to balance the richness of the carpet. Two colors may overpower the space and cut the room in half. A creamy taupe would be beautiful. Also looking at the photo, I think it would add some depth if you add lighter accents. There are beautiful deep tones but the contrast of painting your TV stand a milky white would balance your space. Use accents to add color. Soft tones or bold pops of color in your throw pillows would really set it off. Let the carpet set the tone and then lighten and soften the space. Look on houzz for rooms with deep blue carpet for more ideas. I'd love a client with carpet like that. Your options could be amazing.
