Making cables pretty

What are the best techniques for making cables look pretty. I'm thinking of wiring my rear surrounds with Kimber 4PR. Unfortunately, I'm going to need to wire it along the carpet's edge and then up the wall, since I'm not wiring into the walls right now. Trouble is, the cable is brown, and my carpet and walls are off-white.

Are there any tricks to get the cable to "disappear" (spraypaint? cable covers? tape?).

Thanks,
Matt.
