Black and white filter software

I’m looking for a program that lets me put a black and white filter over my screen, but with a twist, I need to keep about 5-10% of the color. Basically, a control panel where I can adjust the intensity of the black and white filter. Any ideas?

I believe you can achieve that with Adobe PhotoShop.

But that is a photo edition software

I’m sorry. I think I misunderstood the question.

You could try adjusting the color saturation through your GPU’s control panel. For example, with Nvidia, you can make things look black and white by tweaking the color vibrance slider. Just right-click on your desktop, go to Nvidia Control Panel, then “Adjust desktop color settings,” and play around with it.

If you’re using AMD, the process might be a bit different, but they should have similar options available.

Have you tried the built-in color filters in Windows? Maybe they’ll suffice?

I Tried but the program I use is hard if I don’t have a little color.
