What is a red screen used for?
A red screen is used for chroma-key compositing in the rare cases where green or blue would clash with the subject — for example, when a costume or prop is green or blue, or when filming a night scene where red causes less interference.
Why isn't red the standard chroma-key colour?
Red sits close to natural human skin tones, which makes it much harder to cleanly separate a person from a red background without also keying out parts of their skin.
When would a red screen be used instead of green or blue?
Typically when the subject's clothing, props or hair colour already contain green or blue, which would otherwise get accidentally keyed out along with the background.
How does colour separation work in chroma keying?
Digital video represents colour as red, green and blue intensity values per pixel. Chroma-key software looks for pixels matching the backdrop's colour range and makes them transparent, so the choice of backdrop colour just needs to be as different as possible from anything in the foreground.
