What is a gray screen used for?

A 50% gray screen is ideal for spotting uneven backlight, banding and the dirty-screen effect, and it's a neutral reference when calibrating a display.

How to make your screen gray

  1. Click Full screen (or click the color box, or press F).
  2. Your whole screen turns gray. 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.
