Living Room Rug?

I have suddenly fallen in love with rugs. They are so soft and comfy, yet they also work to bring an entire room together. I've never had a house with hardwood floor before, so I haven't had an opportunity to look at rugs...but that's about to change when we move into our new house. These rugs would look gorgeous against the dark wood floor of the living room and against my bright red couch:

I also love this one, but I'd have to find another room in which to put it because it would majorly clash against the red couch:
