We examined the effects of luminance contrast and spatial frequency on chromaticity discrimination of grating bars. Alternate bars of gratings were filled with light of a standard wavelength and light that could be varied in wavelength. The observer set the variable bars to match the standard bars in hue. Discrimination, as measured by the standard deviation of the matches, decreased as spatial frequency increased. Luminance contrast did not improve chromaticity discrimination but did lead to Bezold-Brücke hue shifts that were spatial-frequency dependent.
我们研究了亮度对比度和空间频率对光栅条色度辨别力的影响。光栅的交替条带填充有标准波长的光和波长可变的光。观察者将可变条带设置为与标准条带的色调相匹配。以匹配的标准差衡量的辨别力随着空间频率的增加而降低。亮度对比度并没有提高色度辨别力，但确实导致了与空间频率相关的贝措尔德－布吕克色调偏移。
