An Amazing program if you use your PC late into the night

It basically automatically changes the lighting on the monitor and reduces the brightness and color based on the time of the day.
No thanks, I'd rather keep lightning far away from my machines.
It should be 'lighting' lol
Thanks for noticing
Edit: Now that I think about it, I wonder if its grammatically correct...Perhaps, I should should rewrite it as "It automatically changes the brightness and color of the pc monitor based on the time of the day.
