It also depend on the color taupe, which can play all different shades based on you lighting etc

Taupe is considered a neutral color. I would look for an area rug that has both taupe and black in the design. Teal is a popular color right now and should look good with your other colors.

You are the best! I will look for something like that ASAP.

You are fortunate. Taupe goes with almost everything. Since there are many shades of taupe it would be wise to go to the paint store and find a chip with yours. Then check compatible colors. I use a neutral taupe with beige and wine accents. Since you already have black I would look for a bright color to perk it up...

Leopard, Zebra Or sheepskin.

Taupe is neutral. Anything goes with it.
