Abstract

The perceptual amplification of color, otherwise known as the Helmholtz-Kohlrausch effect, has been experimentally characterized for a common CRT computer monitor and the highly saturated, and pure, colors Red (255,0,0), Green (0,255,0), Blue(0,0,255), Cyan(0,255,255), Magenta(255,0,0) and Yellow(255,255,0). Twenty-four human observers conducted direct brightness adjustment, on a CRT monitor, of the original colors to match the brightness perception of corresponding equal luminance gray images. Experiments were conducted in complete darkness to eliminate the desaturating effect of flare light. Results are presented in both the monitor R, G, B color space and the 1976 CIELAB color space.
