Abstract
The present study examines whether the off effect, the phenomenon of temporal edge emphasis, exhibits any type of wavelength selectivity as in the monochromatic Mach band which is the spatial edge emphasis. At first, off effect measurements were taken using a monochromatic background and a monochromatic test light. The off effect was observed in all combinations of test (red, green or blue) and background (red, green or blue) colors. However, we were unable to demonstrate wavelength selectivity. In the second, the on-off effect like overshoot of increment threshold on the chromatic change of background field was studied. The overshoot was observed in all combinations of test (red, yellow, green or blue) and background (red-green or yellow-blue). However, we were unable to demonstrate any color mechanism specificity. The degree of the overshoot seemed to depend solely on the chromatic difference of the background field. These results suggest that the off effect, a function of temporal specificity, has no relationship to color mechanism.
