Frequently asked questions

What is a yellow screen used for?

A yellow screen displays a warm fullscreen yellow background used for reducing eye strain, comfortable night reading, blue subpixel testing and focus enhancement. Yellow light is less disruptive than white or blue for extended screen time.

Is yellow light better than white for reading at night?
