You're still using your real eyes so it should work. I've been flashbanged by the overlay enough times to know they still try to adjust to low light. Green should do the opposite and help your eyes adjust to bright light. So red if you're expecting it to continue being dark after turning it off or green if you're expecting it to be bright. Also apparently the spawns are scared of the red light? I haven't tested that though because I just use my trusty headlamp.
