today in "huh, they built it with THAT?"
Asus ProArt ChromaTune. It's a little app that sits in your windows tray and can switch between your monitor's color palettes. You can either do it manually, or you can tell it to automatically switch when you run certain programs, so you can do things like "always use sRGB mode when I'm in photoshop".
Wanna guess how they built this?
