Hi

Make sure that the screen is a pure Blue or Green. Buying paint from your local hardware or paint store does not always key well due to the other color pigments in the paint. Most or all stores use white as the base color. Too much white in the color will also make it harder to key. True Chroma green or blue paint runs about $50-75 U.S. Dollars a gallon. You also can buy Chroma Key fabric from $15 to 20 dollars U.S. a yard. See last link for provider of keying products.
Make sure that your lighting is set up properly to reduce shadows. The color temperature of the lighting can also cause problems. This is a coloring being cast from the light source, i.e. florescent lights can cast a blue hue. These types of poor lighting conditions can affect the screen color and or the subject. I work in the broadcast/movie industry and have painted the sets for use of this effect but I am not an expert on this subject. My main background is broadcasting (getting the stuff on the air)
Below are some links to some sites on Chroma Keying.

yeah its difficult to get a good key . i managed to get it looking pretty good. I bought some green fabric at the fabric store . it is very close to green 255 . nice and bright. I am using flourecsant lights to illuminate the screen behind me and plain incandecant bulbs to light myself. It doesnt look professional but it looks pretty good i think.
