How to change the color of the white across all applications?

With the advent of Dark Appearance (System Preferences, General) macOS became more pleasant to use on a dark room. Since Dark Appearance turns dark (or darker) many parts which used to be white (or brighter). However somethings are still not affected by the Light/Dark appearance control, i.e. this website. It is perhaps outside the boundaries of what the OS can do, I actually don't know. Is there someway we can tint the white? I would like to do it across all applications. If that's not possible perhaps I should keep using Light Appearance and reduce screen brightens. That would be and unfortunate solution though.
