What color of blue paint should I use for a Blue Screen?

Question

Like the screen they used for the movie 300.

Answer 1

There is no particular blue anymore. It can be any color you want. Modern computer technology will filter out any color you tell it to.

(from Wiki) 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 or Predator). 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, and yellow was used in Doctor Who because a number of props and costume items contained both blue and green.

Answer 2

If you're thinking of painting a blue screen for video editing purposes, blue is not as common as green. But it depends on the foreground subject. The process is called chroma keying. You can chroma key using any color, even white. The editing system is simply set to ignore that color. Green is common because the unique shade of green used is rarely found in human, eyes, hair, skin tones, or clothing.

The challenge is lighting the screen evenly so it appears the same shade across the entire surface. For small subjects, I've used bright green craft paper.

Video lighting suppliers sell large sheets of green and blue paper. Some sell the special paint colors.
