Abstract: An investigation into the stability of color appreciation after repeated testing with a light emitting diode (LED) system was undertaken. Experienced subjects viewed a LED simplon that had been set at a plateau intensity (in the photometric range), the principal variation being pulse duration (16 to 320 ms). A forced-choice color naming technique was applied. The investigation revealed a red shift for short duration exposures and an intense yellow shift for long exposures. Prolonged repeated testing produced a peculiar effect in the midrange: a loss of color, supplemented by a white effect, interpreted as a masking or tuning effect, by the achromatic channel.
