I use the built in accessibility "Color Filters" in Mac with the Menu Bar shortcut to toggle it on/off

Somewhat related: I really like f.lux's "Darkroom" feature. Although I no longer use the app to reduce blue light after the advent of macOS's Night Shift, Darkroom mode tints the screen completely red (like a red version of Color Filters). It's great for working during the wee hours.
yes, definitely I am with you at that point, they are a great way to do this without a doubt although I am a windows user (lol) and also even if it's very fast to toggle the color filters via shortcut keys. I don't think so that I will be willing to toggle it off when I visit any work-related website like GitHub, Figma and such so site exclusion of this extension works really great for me in that perspective.
