Examines how sub-fusional intermittency affects color and brightness perceptions in achromatic targets, suggesting wavelength composition influences these effects.
The effect of sub‐fusional intermittency on the appearance of targets of complex spectral composition were observed. Achromatic targets of varying spectral composition, purple targets, and metameric pairs of targets were examined. A daul‐beam optical arrangement was used in conjunction with narrow‐band interference filters to produce complex targets with known spectral composition. Brightness matches and verbal judgments of hue and saturation change were made with four conditions of intermittency. Results suggest that temporal effects on brightness and color are dependent on the wavelength composition of the target in a simple way.
