I am planning on using a glass colorizer gobo with a 70 deg. source four to throw an interesting splash on our curtain before the show and during intermission. I am planning on hanging the fixture at the far right side of the catwalk that we hang our face light on shooting across the curtain. Is there anything that I should be concerned about when I do this? Will this look strage with only one fixture instead of two? What have some of you done to get an interesting look on a solid piece of fabric? Notes: I would just test it out but I am renting the fixture. The curtain is that classic bright red "theater rug" color.
