Questions

Is this the blue screen of death?

No. This is a plain blue color screen. For the crash-screen prank, use the Blue Screen Prank page.

Should I use blue or green for chroma key?

Green is more common because cameras capture it well. Choose blue if your subject wears green.

Can I download this as an image?

Yes. Choose a size and press PNG to save a solid blue image, up to 8K if your device allows it.

Can I send someone this exact screen?

Press Share to copy a link that opens the page with your brightness setting.
