After finally going through a 3-D attraction this past season (Shady Brook's Alien Invasion, Yardley, Pa.), I'm considering 3-D for part of my haunt. From what I could tell during my walk through with the chromadepth glasses, it appears as if the paint is on sheets of glass standing vertical about an inch or two from each other. Hotter colors up close (red, orange, yellow), cooler colors (blue, green, purple) toward the back. If you can establish the progression of paint colors (cooler to hotter shades), you should be able to pull it off without too much trouble. Experiment on a smaller scale. Play around with colors and textures to see how they work together. The colors seem to literally float off of the walls, props, makeup, etc. Phenominal.
