So we have a production studio here at my work with several colored backdrops, a green screen, and blue screen. We are going to order chroma key green paint to paint the wall behind the backdrops and also want to get something for the floor but it cannot be permanent as we want to maintain functionality of the rest of the screens. We do not want to use any kind of paper or whatnot like was suggested in another thread from 2008 that I was reading on here. Also, painting the floor is not an option. It is a fairly small room so keep that in mind. I have found the mats from: and from but these I don't believe are the true Chroma Key green (#00ff00). Any other ideas or suggestions for our floor?
