How to use it
- Click the blue box above, or press F.
- The whole screen turns blue. Move the mouse or press an arrow key to see the controls hint.
- Click anywhere or press Esc to go back.
On an iPhone the browser keeps its address bar, so the color fills the page but not the very top strip. Turn the phone sideways or scroll a little to hide the bar.
What a blue screen is for
- Pixel test. Pure blue lights only the blue part of each pixel. A black dot means that part is dead.
- Blue light and backdrops. A blue screen behind a small object or a person works as a blue backdrop for photos.
- Backgrounds. Download a blue image in any size.
Not the Windows error
This page is just the color blue. The "blue screen of death" is the error screen Windows shows when it stops working. If you see that on your computer, it comes from the computer itself, not from a web page.
Questions
Is this the blue screen of death?
No. This page only fills your screen with blue. It does not show any error and does not change your computer.
How do I exit?
Click anywhere, tap the screen, or press Esc.
