Does the carpet match the decor?

It's actually the other way around. The decor should be based on the rug.

Any good interior designer will tell you the foundation of the room is the rug.  

There are 3-4 dominate colours in any area rug. It's much easier to coordinate colours by choosing the rug first then by working backwards. 

There are also  5-6 accent colours found in this designer rug. You can choose upholstery for the pillows for your couch/love seat based on these colours.
