When the rays are drawn the flux of each ray segment will be compared to the color scheme and drawn in the defined color. The Peak flux of all rays traced will be used as a normalization factor for the flux ratios defined. The default scheme will draw Red ray segments which have flux equal or greater to 0.666 * Peak Flux or From * Peak Flux.
