Blue Screen

A free fullscreen blue screen you can dim or download as a PNG, for mood lighting and backdrops.

A free fullscreen blue screen for mood lighting, background use, and screen testing. Adjust the brightness, go fullscreen, or download it as a PNG at the resolution you need.

Blue also reads as calm rather than energizing, which is part of why cooler tones are a common choice for evening desk lighting or a bias light behind a monitor. It's a simple way to add some color to a room without the sleep-disrupting intensity of a full white screen.

How to use it

  1. Set the brightness with the slider in the settings panel.
  2. Tap the fullscreen button on the color area. Press Esc, or use your browser's exit control on a phone, to leave fullscreen.
  3. To keep a copy, pick a size under Download (1080p, 4K, or your own screen) and save the PNG.

Watch out for: blue-light filters such as Night Shift and Night Light cut exactly this color, so with one switched on, this screen looks noticeably dimmer. Turn the filter off to see the real blue.

Frequently asked questions

Is this related to the "blue screen of death"?
No. This is a solid blue display for lighting, testing, or backdrop use, unrelated to a Windows system crash screen. If you're troubleshooting an actual computer error, this tool won't help with that.
Can I use blue instead of green for chroma key?
Yes. Blue is the standard fallback when a subject is wearing green or has green in the background, since blue and green are both far enough from skin tones to key cleanly. For real keying work, the dedicated Chroma Key Screen tool includes a proper blue option alongside a grid overlay and other backdrop-specific settings this simple color page doesn't have.

Cedrick Reese built this page as part of WhitestScreen.com's color set. The blue is #2563EB, a deep blue rather than pure #0000FF, applied directly as a background color in your browser. For a strict subpixel check, the Dead Pixel Test uses pure primaries instead. The value is fixed in the page's code and no outside data feeds it.
