Bottom right of Google.com -> search options -> appearance. Or go here: https://www.google.com/preferences?hl=en&fg=1#appearance

Must be rolling out still, I see no appearance settings.

This works for me:

"Google Search Page" -> Setting (icon, upper right) -> "Dark Theme: Off/On" (Last Entry in the drop down menu)

I use Dark Reader extension: https://chrome.google.com/webstore/detail/dark-reader/eimadp...

Works pretty well for 99% of sites.

I'm not necessarily asking you, but I'm taking your message as an opportunity to ask if anyone knows of an extension that does the opposite?

I have pretty bad astigmatism, and I cannot read pages with dark background. There used to be an extension I used for this purpose, but it stopped working several years ago, and I have suffered ever since. Going into developer mode to play around with the stylesheet works, but is a huge hassle.

Despite its name, that same extension does exactly that, I believe.

Actually, it has a switcher that lets you choose to darken or enlighten the webpages you read.

Honestly, I never understood why they had that option, but now I get it.

If you have a Mac it will follow your Mac's dark/light setting. At least it does for me, maybe it's still rolling out.

I recently received this feature as well. They are probably rolling it out gradually.

I typically browse in ephemeral sessions and Google has been flickering light and dark for a few weeks.
