I'll start by saying I love most things dark mode. My phone, my computer, Discord, Slack, everything I can for the most part.
However... I really dislike darkmode that was added in 21.02.1. The blue against the black is awful. I'm guessing some people like it but I hate it almost as much as I hated the new purple firefox logo. Is there an option to turn it off? I can't find it if it exists.
I think it would be find if it was white text or something else but that blue and black is too much
Note that dark mode in its current form is more or less a naive inversion of the color values. There’s certainly room for improvement, but that requires constructive actionable suggestions.
Will look into implementing a config override for enabling/disabling/auto-toggling it.
Dark mode appears to follow the browser or OS global setting. As of now, I am not aware of a way to toggle it within LuCI, but it should respect the setting up of your browser or OS - just tested with the iOS system settings for dark mode and safari.
If you opkg upgrade luci-theme-bootstrap to the latest version, you'll be able to toggle between "Bootstrap" (light/dark depending on OS/Browser settings), "BootstrapLight" (force light) and "BootstrapDark" (force dark) in the System->System->Language and Style design selection config.
