How can i make the game area pitch black

Im trying to make the game area totally dark but when i turn off the directional light it just makes it go similar to dusk while im looking to get it pitch black.

How can I do this?

Go to Window–>Lightning–>Ambient Source–>Color and then set the color to complete black.
That should do it!


Go to Window > Lighting > Scene and set Ambient Intensity to 0. This will make no ambient light in the scene.
