A series of experiments were carried out to reveal determinants for the mode of color appearance by measuring the upper-limit luminance of a color chip for the surface-color mode. We used a CRT color monitor to present test and surround stimuli in the surface-color mode. The stimuli were composed of a three-by-three array of color chips on a gray background with a white frame. The observer increased the luminance of a center test color until it just ceased to appear in the surface-color mode. Our results show that this upper-limit luminance was different among test colors, but their brightnesses, calculated from the luminance and brightness/ luminance values, were almost the same and were slightly below the brightness of the white frame. The existence of the surrounding color chips affected the results, but their sizes and spatial arrangements did not. When all of the luminances of the surrounds changed equally, the upper-limit luminances of the test colors for the surface-color mode appearance changed by the same ratio. This result indicates that the brightness of a target was a determinant for selecting the mode of color appearance and that the brightest surround stimulus acted as a cue for determining the judgment.
通过测量色片在表面颜色模式下的上限亮度,进行了一系列实验以揭示颜色呈现模式的决定因素。我们使用阴极射线管(CRT)彩色显示器在表面颜色模式下呈现测试刺激和背景刺激。刺激由灰色背景上带有白色边框的三乘三阵列色片组成。观察者增加中心测试颜色的亮度,直到它刚刚不再以表面颜色模式出现。我们的结果表明,这种上限亮度在测试颜色之间是不同的,但是根据亮度和亮度/亮度值计算出的它们的明度几乎相同,并且略低于白色边框的明度。周围色片的存在影响了结果,但其大小和空间排列没有影响。当所有背景的亮度同等变化时,测试颜色在表面颜色模式下出现的上限亮度以相同比例变化。这一结果表明,目标的明度是选择颜色呈现模式的一个决定因素,并且最亮的背景刺激作为确定判断的一个线索。
