fade out black on touch with collider

Im trying to make a Game fade out to a black screen when a first person controler touches a trigger

Im planing to have a voice talking while the screen is black and then the game is to automatiacly close (shut down) so being able to tweak how long the screen is black is another variable to make things even more complicated

any help at all would be greatly apreciated
