What is a blue screen used for?
Pure blue lets you test the blue sub-pixels of a display, check color uniformity, and use your monitor as a backdrop for blue-screen keying.
How to make your screen blue
- Click Full screen (or click the color box, or press F).
- Your whole screen turns blue. The controls and mouse cursor hide after a couple of seconds.
- Use ← → to switch colors without leaving full screen.
- 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.
