Potential PS3 HT System

[LemmingsOwnYou]

Here's my dilemma. The back left surround speaker should probably go where the red circle is. The receiver/TV is off to the right.

RED: I could run a wire up and over the bedroom door(right doorway), it might be kind of hard to hang it across the kitchen doorway(left doorway).

YELLOW: I could try to run the wire under the carpet across the bedroom there and then tuck it into the metal bar across the kitchen and then up to the speaker.

OR BLUE: Run it across the floor, buy a rug to put over the wire...

What do you guys think would be easiest?
I could paint the wire to match the walls.
