The other night I suddenly noticed that my screen looked "funny" - it wasn't quite as bright, the colors looked a little more yellow-ish.

I immediately went into anxious problem solving mode. Was my power cord fully plugged in? Was my battery getting low? Worse yet, was my video card failing? No idea, and nothing I tried made any difference.

The next day, colors looked normal and all seemed well, and the next (although on both days I stopped working on the computer pretty early). Jump forward to today, and all seemed well until a little bit ago - when it happened again! (You can see this coming, right?)

After some more angst, it turns out it wasn't a bug but a feature - yep, I had totally spaced the fact that I had turned on the night light setting a long time ago and it was working like a charm

Don'cha hate it when you don't know what you don't know?

Oh, yeah - running Version 1909 (Build 18363.1016) about to update to 2004 (19041.450).
