The only way to eliminate light is to absorb the photons. There isn't anything that will emit an "anti-light" that will cancel the light out. The only thing that that we know of that will completely absorb light is a black hole, and I don't think you want on of those in you living room.

Because dark is the absence of light. Therefor to achieve dark you need to remove/block/turn off the light.

Dark is a lack of light just like quiet is a lack of sound. They are not things we can produce like sound or light.
