Especially if they’re dark (literally midnight) blue, which is what my screen currently looks like!

I’m going with my feelings on this one. To me, an untinted white screen is like a standard LED lamp - it screams “Morning! Time to get up!” (which is why my lamp is covered with orange cellophane). A (heavily) red-tinted white screen feels like sunset. And my dark screen feels like, well, midnight. I sleep like a baby so in my case the problem’s solved.
