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.

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.
