You can pick just about any color of the rainbow for the common cars, and different types of carpet too. There are some mixed issues with installing non-OEM carpet, so keep that in mind. You might not have all of the cutouts and reinforcing pieces and that type of stuff, but that's not an issue in most cases as all of that will get covered by seats, trim, etc.

There are a lot of places out there, google "automotive carpet" and you'll get a ton of stuff. Try to find reviews from customers on forums and stuff though, because some of the aftermarket carpet fits like complete shit.
