The perceived color of a region of visual space depends both on the spectral composition of the light incident from it and the light incident from surrounding regions. We studied the induced effect of combinations of colors surrounding a central test disk. Surround colors varied in a radially sinusoidal fashion around the perimeter of the test. Using a modulation nulling technique we show that when DC adaptation is controlled, the combined effect of such surrounds is equal to the sum of contrasts induced by individual elements of the surround. This result holds for both lightness and chromatic induction.
