Help finding a rug.

[becky8475]

I am redoing my family room/kitchen area.  It is all open to each other and the patio door/big window in the family room are on the same wall facing the back of the house.  I got these curtains at Target last night for the patio door to hang with a traverse rod.
They are brown & cream.  I am going to hang just plain brown curtains in the family room area, I think. I am not sure what kind of rug to put in the family room.  I need some color because our walls are tan, couch is tan, floors are dark wood, woodwork is dark wood.  I would like to bring in some blues or greens, but I am not sure about mixing the prints witht the floral curtians even if they aren't in the same "room".
