What is a red screen used for?

A solid red screen helps you find dead or stuck red sub-pixels, works as a dim night light that's easier on dark-adapted eyes, and makes a quick party or mood light.

How to make your screen red

  1. Click Full screen (or click the color box, or press F).
  2. Your whole screen turns red. The controls and mouse cursor hide after a couple of seconds.
  3. Use ← → to switch colors without leaving full screen.
  4. Press Esc, double-click, or tap Exit to go back.

Tip: turn your display brightness up for a stronger light. While full screen is open, the site asks your device to keep the screen awake.
