The application f.lux works on your Mac and adjusts the colors during the night hours. Think of it as dimming the lights in your apartment as you wind down for the evening. The application warms the colors on your screen during evening hours so your eyes and brain can relax in the low light while you stare at the screen. Once installed you’ll be able to adjust how much the screen changes, as well as easily disabling it for times when you need true colors on screen.
