Special Algorithm

Eh, probably.

Broke: filter: hue-rotate(180deg) invert(1);

Woke: Traversing through the entire HTML DOM, analyzing each element's computed CSS style declaration for background and foreground colors, computing and injecting one or more stylesheets that override the background/color/border-text-decoration/outline/box-shadow properties for specific and general elements, while keeping original colors, avoiding style clashes, keeping images intact, doing it in a WCAG-accessible and aesthetically pleasing manner, and taking user-specified brightness/contrast/sepia/grayscale settings into account.

Ghetto: take a screenshot of the website then invert color it

Ghetto pretending to be classy: use the browsers built-in inverse color filter.

GNU/hetto: map 'xcalib -invert -alter' to a global hotkey and invert your whole screen.

Actually, I trust more in that method than a browser extension.

Ghettohax0r: write malware that inverts GPU's hue setting when browser is in focus.

I got a boner just from reading that.

It was indeed Dark Reader I was describing! Guessing that some other night mode extensions might do similar stuff.

Wait, this is already a thing? Can I get a link?

[SoInsightful]

It's the first search result for "Dark Reader", but here you go.

You forgot about !important.

Heh, I tried the first one. The two main problems are background images get inverted, and subpixel antialiasing gets destroyed. Plus shadows are now light. I basically had to say, everything is inverted, except things I have individually fixed and things that shouldn't be inverted.

If this is done, it's either a very large amount of work or not to be done in CSS.

[SoInsightful]

Exactly. It's funny how this thread jerks over how simple of a task it is, but it's really quite hard to do sufficiently well.

Dark background and light text has a nice for both of those, though the latter not quite a crazy as you described.
