I've always liked the combination of black and tan, or black with khaki. Something like SW Canvas Tan could work. It's a good neutral that would be nice with black.

Here's Canvas Tan on the upper walls...

Almost any warmer shade of gray, tans , blues, etc. Depends upon your color favorites...

Hi Megan,

I agree that it depends on what colors you are partial to. A bright color could look great, but keep in mind if you do a vibrant color it will appear even brighter with the black leather sofa, to contrast it. If you do go with a bold color, I would suggest downplaying the amount of color you use when displaying art above your sofa. Opting for a large clock, mirror, or decorative metal piece would look lovely!

Thank you! After your responses, I will look further into tan as a wall option.
