Who makes Beautiful / Attractive Speaker Cables?

I am going to put a system in to the master bedroom. Linn Classik Di, Opera Callas speakers, HD TV. Hiding the speaker cables under the floor or thru the walls is not an option. Who makes attractive looking cables that are sufficiently audiophile quality. As much as I love the sound the unbelieveably bright blue Siltech cables will NOT work. Any thoughts? Are flat wires attractive? Obviously thinner would look better but may not sound as good as their larger diameter counterparts. What colors have you seen that might work on a light wood floor with a beautiful carpet? thanks.
