In the browser settings I use a color preference that replaces white with black, this works with pages where Dark Reader is not available. These settings are needed so that when surfing the web at night with the dark mode on, my eyes don't hurt from contrasting bright white elements with dark-colored pages. For example, it works on single image pages - in situations where except for the image the rest of the page is colored solid white; It also works for some add-ons - on settings pages and pop-ups.

I'm interested in being able to automate toggling on/off the «Use system colors» checkbox, which is in the browser «Color» settings. It would be great to somehow synchronize the activation of night mode in Dark Reader with disabling checkbox responsible for using system colors. Or, for example, make it so that when the «Website appearance» setting is set to «Automatic», the checkbox is switched accordingly together with it - being disabled when the appearance is dark and enabled when it is light.
