We describe the results of an experiment designed to test the accuracy of the Helson-Judd formulation in predicting the perceived color of objects in two-primary projections. Five trained subjects gave color-naming responses for hue, lightness, and saturation of perceived color in computer-generated artificial images viewed in red and white projection. The averaged results indicate predictions that are 90% correct for hue, 81% for lightness and 61% for saturation at mesopic luminance levels, and 83% correct for hue, 67% for lightness, and 78% for saturation at photopic luminance levels.
