How to install a color filter on the screen?

Question

Color Calibration

The filter must run in the background. The same as filters on a video or photo, only here it should work when the PC is running all the time: YouTube, desktop, Word, etc. Tell me a program that can do this. It can be not very fancy, with a minimum choice of colors. Something like "tinting" the screen) Google throws out answers with the theme of Windows 10, like Deuteranopia. This is not it. Color calibration is also not the same. You need a color filter. Thanks

Answer 1

It's not very clear what result you expect, but the colors can be twisted in the video card driver settings. Nvidia for sure.
