I really like the Bedtime Mode that Android has as a part of Digital Wellbeing. At a specified time, it will turn the screen grayscale, dim the wallpaper, etc.
Is there an equivalent setting or app for Windows? Bonus points if you know of a Linux equivalent too.
GNOME and KDE both have a built-in nightlight feature (reducing blue light after a certain time). Not seen one that will turn the screen greyscale myself.
Edit- Actually I think I’ve found exactly what you’re asking for: https://fostips.com/gnome-bedtime-androids-bedtime-mode-linux/
