We've bought a red (Alera Tomato) slipcovered sofa for our casual living room. Really struggling with deciding a rug to go with it. Picture shown makes it look much brighter (and more garish) than it is. Don't pay attention to the pillows; we will purchase different ones separately.

We are aware that the rug doesn't have to have red in it. We're fine with pattern or solid.

Walls are typical beige. Other furniture is on the beige spectrum.

Thoughts? Example photos? Thanks so much.
