Answer 1

I remember it being used in TV in the 70s. I had a friend working at the Film & TV school and visited him. The students were using it. I think it had been in use for some time then.

It was originally a blue screen and is still known as that in some places.

Answer 2

Developed by Warner Bros. employee and ex-Kodak researcher Arthur Widmer in 1950, he began working with an ultra violet travelling matte process. Widmer also developed and refined technologies for other motion picture processes including 3D and widescreen. He began developing bluescreen techniques, with one of the first films to use them being the 1958 adaptation of the novella by Ernest Hemingway written in Cuba in 1951, The Old Man and the Sea, starring Spencer Tracy.
Other colors are sometimes used instead of blue, including magenta (The Matrix), yellow (some 1970s episodes of Doctor Who, and Song of the South), orange (Apollo 13) and red (Air Force One). The choice of color depends on the subject and specific technique used. Blue is normally used for people because human skin has very little blue color to it. Green is used because digital cameras retain more detail in the green color channel and it requires less light. Magenta screens are often used with model photography where the model contains both blue and green components.
