There were two purposes in the present study. The first was to find quantitative relationships in chromatic inductions between the inducing colors and the chromatic shifts produced in a test field based on the responses of photoreceptors and opponent color channels. The second was to investigate the spatial integration of chromatic inductions. Using a nulling method with a haploscopic view, magnitudes of chromatic inductions were measured with multicolored surrounding fields. The effects of chromatic inductions on achromatic locus could then be represented by power functions of opponent chromatic responses of the surrounding colors. In regard to spatial integration, we concluded that when a white test field was surrounded by a multicolored field, the apparent color shifts in the test field could be explained by the sum of the induction effects produced individually by the surrounding colors.
