        California = Green
        London = Blue

        Must be the sunlight, what should we use in Asia :)

        p.s. Nice color space story btw...

          The bottom line is you can chromakey on just about any colour. Green and Blue are chosen primarily because there is less chance of those two colours appearing in the human body.

            Red pops up on occasion, but usually this is only for special cases or keying objects, not people.

              blue is usually the best if the background that will be keyed is outdoor footage

              example, a person standing in your studio in front of blue screen and then you replace blue with beach and blue sky, simple keying pleasure

              be sure to light the subject with 5600k lights

              I use dual purpose twistfold screens, blue on one side, green on the other, folds up easy

                That's simply covering up a bad key. Blue on blue or green on green is a hard pick for edges. Red on green and your going to see it.
                Anton, how do the Kelvins on the background affect the overlay? Two different sources. Whatever you key out is gone forever.

                  by using 5600k on the subject, it will look like the subject is outdoor and the key edge is much cleaner then when using 3200k, try it, you will be very surprised

                    Don't forget Red Screen is used a lot in the industry as well!!

                    Almost exclusively use Red Screen now for stop animation.
                    Main Editing System: Sinclair ZX81 0.75Mhz chip (Overclocked to 12Ghz), Liquid Nitrogen Cooled. 48k of RAM, Compact Cassette tape drive (9600 baud), 4" B&W monitor. No keyboard - all input by thought transfer from a colander on my head. Gives me 180 layers of 4k in real time (all with 3D PIP added) and can encode and burn a 2 hour Blu Ray in just under 12 seconds. Custom editing chair that floats on magnets 2 feet above the floor. I am also able to travel in time.

                      Playing with blue and green, and with HDV footage, the green was much cleaner for me.

                        Green is a major component of human visual color perception of brightness, hence YCbCr encoding gives more preference to green. This means there's more data for green, whereas in RGB they're all equal, and that's why RGB takes up more space data-wise.
