I'm actually kind of annoyed at prefers-color-scheme, and the inability to control it as a user in my browser.
I have my Windows set to dark mode because I prefer how Explorer and the rest of the Windows UI looks in dark mode, and I want my OS chrome to be less distracting and to just "fade away". However, all web browsers see this as a signal to tell every website I would prefer them to be in dark mode also, which is not correct! I wish I could set chrome itself to prefers-color-scheme: light (without having to use the dev tools on every website).
