If you're running Windows 10, there are built in night-mode capabilities including intensity and timers, so Flux wouldn't really be needed.Light mode for everything, especially PC! The only exceptions are Discord and fanfic.net (their white modes are blinding!). I don't have a problem with white websites at night really because I have Flux installed, which dims the screen to a soft yellow that's easy on the eyes.

I actually didn't realise there was a built-in night mode until fairly recently, but I've had Flux for ages and I just like how accessible it is having it on my taskbar! I manually adjust it all the time so the convenience is nice. ^^
