Beautiful but dark and heavy. For walls, consider a neutral that is lighter and brighter - not so much that it causes much contrast - but enough to give it a lift. Artwork that is not too small and has red in it will add life.

The current wall color looks just fine. Perhaps add some colors through accessories as mentioned.

I like the current wall color. But if you are looking for a change then, I think a light blue, green, taupe or gray shade would compliment all of the dark wood. Along with some pops of color with décor- photos, pictures, curtains, pillows, vases, flowers etc. Have fun with it, make it what you love!

Ben Moore Toasty Grey. It'll be gorgeous!
But if you want a hint of color: Ben Moore Half Moon Crest. It will have a hint of blue green to it. It won't look like it if you look at the chip. But it will! Check it out. See the Magnolia Bedroom done by Hyde Evans Design.
