Hi, we're doing some color contouring of scalar values on 2d and 3d meshes of polygons. Currently, we use a rainbow color scale that varies in equal increments of hue in an HLS color system. Obviously, the same distance between any two colors does not have the same perceptual distance. I know that a lot of work has been done with color perception and color science. Tektronix has their TekColor color system that is perceptually equidistant. What we are looking for is a set of HLS or RGB values that would define a rainbow color scale that is perceptually equidistant. It is assumed that there would be a linear variation of HLS or RGB between the specified values in the set. Our main concern is how the colors look on the monitor. I know that once we print them or videotape them, they'll look different. Can anybody help? Thanks in advance, e-mail please Bob Lipman
