Синій екран

A blue full-screen works as a backdrop or chroma-key surface for product and portrait photography when green doesn't fit the subject.

Before digital keying, film used blue screens — and blue still works where green would clash with the subject's colors.

A solid blue screen helps lighting teams judge how reflected color falls on a subject, and verifies an even keyable tone edge-to-edge.

A muted blue full-screen behind you reads as calm and professional on camera, a solid alternative to busy virtual backgrounds.

Display pure blue to verify color accuracy, check for stuck blue subpixels, and compare against green and red during tests.
