We have used a lot of different greens and all very successful. Chrome Key green is made for “Ultimatte” machines and that box looks for a particular color with a lot of yellow in it.
Do this: Go to your local Art Supply Store and find their Foam Core cards. They come in lots of colors including a bright green, about 18″ x 24″ and around $5. Test this green with your camera. After you’re completely amazed at how well it works, take the card to a paint store and have them match the color. A gallon flat washable paint is around $17 to $20.
Light your background at 40%, caucasion skin at 70%, keep your subject 12′ away from the wall, side light them with a touch of magenta.
Simple stuff.
