I found a very odd Google search bug/misfeature on android: I've somehow gotten stuck in Brown Mode.

It happens in both Firefox and Chrome, and as long as I'm signed into my account, it's brown.

There's no color theme settings I can find, and while I thought this was a dark mode issue, the dark mode options are quite minimal:

And all three of those options either give me the regular non-dark theme, or the new Brown theme.

None give me the Grey Dark Theme, the one I get when I'm logged out.

Grabbed a tablet: logged in or out over there gives me the grey theme (Although it looks bluish there, which could mean everything or nothing).

Possibly important note: the tablet is logged into a different Google account

It's been suggested this could be a dynamic coloration based on androids dynamic themeing. Nope, changed my wallpaper to completely different colors.
I also tried applying the "color palette" feature (which was off) to make my whole OS pink and blue. Still brown.
Same for the OS-level dark mode. I had it on, but turning it off (and turning on the Google-search settings dark mode) still gives me brown.
Also not affected by if Firefox's dark mode is off or on.
I'm starting to think we have too many dark mode switches.
You should have one, not multiple intricately nested ones, but I fully understand why it's not easy to make it work that way.
