Hi! Since I don't know your color scheme, here are some neutral rugs to get you started:

(also comes in brown and other colors)

thanks, my walls are a linen color, the couch is a metallic grey, the curtains are black/grey and cream, looking to add a pop of color

Fuchsia, chartreuse, yellow work very well with your color scheme.

I like this yellow, especially because of your linen walls…this is Ben Moore sulphur yellow

Yes! You have got it made. Either the yellow or the fuschia / magenta scheme would look smashing, whichever you are more comfortable with! Love the throw cushions above, lively, fun, stylish. The black and white rug in the Willowgrove Living Room pic is awesome and makes it easy to ring the changes with other accents.
