If the simultaneous color contrast pattern is covered by a white tissue, a vivid color can be perceived for the test patch. we measured the perceived color by the elementary color naming method. The relationship between the color appearance of colored paper and that of the same paper with tissue showed desaturation of color with tissue without change of the apparent hue. The relation of the color appearance of the colored surround with tissue and that of the central test patch with tissue, when expressed by the apparent hue angle, was very similar to the relation found by the two-room technique, implying that the tissue was caused by the perception of illumination over the colored surround perceived through tissue.
