Abstract : Subjects were instructed to make wavelength settings for various hues by an absolute method in the presence of surround-field colors or darkness. Surround- and testfield colors were equated in luminance. The subject's compensatory shift in setting for the maintenance of a test-color is taken to be the difference between his wavelength setting for the test-color in the presence of the surround-field color and the wavelength setting for the test-color with a dark surround. In general, the compensatory shift in wavelength setting is always in the direction of the background wavelength. A discussion regarding the nature of the shift setting is given. (Author)
