ABSTRACT

The effects of unique blue, green, and yellow pre-exposure fields on spectral hue have been determined. The observed changes in hue cannot be easily summarized. They are not completely consistent with a complementary-shift rule. Nor are all shifts in the direction of the adapting wavelength. Neither the von Kries Coefficient Law nor the Hering Opponent-Colors model accounts for all of the data. The two-process model of Hurvich and Jameson seems consistent with all of the effects of successive chromatic contrast on spectral hue.
