Pop of color with Teal

everything is gray and black so once again everything will go with it. are you going to put a rug with color?

The walls look like they're already a good color. Use that money to buy art for over the sofa.

Stick with a cool-toned paint color and insert a textured painting in the empty space.

Maybe introduce a color that would compliment the gray and use a rug that pulls it all together?

The elements in your room look like they have a blue undertone (from what I can tell on my monitor, anyway :)), so I vote for a painting that features the color orange.
