go to your settings (press winkey+i). go to ease of access. color & high contrast. apply color filter to off. you might have accidentally turned it on.

Yeah, someone at Microsoft thought that we needed a hotkey to turn the screen into a 1950s black and white TV. Try it: control-windows key-c !!

I did that and it still didn't work and it was off
what else can I try?
