Free-choice colour matches were made by 50 young normal trichromats on an anomaloscope. Six equations, of the kind 'blue' + 'green' = 'cyan' + 'yellow', were used in which the stimuli were defined by narrow-band well blocked interference filters. The stimuli were selected so that the instrument controls, which varied the quantities (blue/green), (cyan/yellow) and (cyan + yellow), were nearly independent controls for hue, saturation and brightness respectively. 'Yellow', 'green' and 'cyan' were fixed at 589, 499 and 480 nm, respectively, and the least interindividual variation in blue/green was found for 'blue' in the region 430-439 nm. This and a similar finding in the pilot study of Moreland and Young agree with expectations based on the density spectrum for macular pigment measured by Ruddock. Matches made by a few selected subjects, when the saturation control was locked at a position for the population mean, in the presence of large but typical saturation differences, were the same as when all three controls were used.
50名年轻正常三色视者通过色差仪进行自由选择颜色匹配。使用了六个等式，如“蓝色”+“绿色” = “青色”+“黄色”，其中刺激由窄带良好阻挡干涉滤光片定义。选择这些刺激是为了使仪器控制分别改变（蓝色/绿色）、（青色/黄色）和（青色 + 黄色）的量，从而分别几乎独立地控制色调、饱和度和亮度。“黄色”、“绿色”和“青色”分别固定在589nm、499nm和480nm，并且在430 - 439nm区域发现“蓝色”的蓝色/绿色个体间差异最小。这一结果以及莫兰德和杨的初步研究中的类似发现与基于鲁多克测量的黄斑色素密度光谱的预期相符。当饱和度控制锁定在群体平均值的位置时，在存在大但典型的饱和度差异的情况下，少数选定受试者做出的匹配与使用所有三个控制时相同。
