Don't use RGB LED strips. They are pointless and useless for a room meant for display viewing. It's only to wow yourself or guests but serves absolutely no benefit to increase the perception of contrast from your display or more importantly, lower eye fatigue. Don't fall into the noob trap. The process of removing lighting that isn't right is not worth the trouble.
If you are serious in bias lighting, get D65 white LED bulbs or strips from cinemaquest. They are not cheap, but they are the closest to D65 you can get from LEDs. Otherwise, go traditional and get Fluorescent lamps.
