Abstract

Hues perceived in two-primary projections were predicted for all combinations of pairs of 31 different spectral primaries by use of our computerized version of the Helson–Judd formulation. The computer was instructed to note the absence from the predicted hues of any of the full possible complement of red, yellow–red, yellow, green–yellow, green, blue–green, blue, and red–blue. Experimental confirmation of the computations is reported, based on color naming by trained subjects of the cells in computer-generated quilts projected with a selection of near-spectral primaries. The results of these investigations confirm the usefulness of the Helson–Judd formulation as a means of translating from chromaticity to perceived color in colored displays.
