What style/design/color rug should I get that would match?

I am at a dead end of ideas.....I have 2 large solid color chocolate brown suede like couches with a paisley print chair/ottomon (chocolate brown, tanish, gold) and marble coffee table and end tables (chocolate brown/light brown marble) and the marble is inset in dark brown wood. I can not figure out what color/design rug to put underneath the coffee table.....do I go with a solid color and if so what color! UUGGH! I dont know why I cant figure this out! Thanks to all who take the time to suggest!
