We used hue cancellation and focal naming to compare individual differences in stimuli selected for unique hues (e.g., pure blue or green) and binary hues (e.g., blue-green). Standard models assume that binary hues depend on the component responses of red-green and blue-yellow processes. However, variance was comparable for unique and binary hues, and settings across categories showed little correlation. Thus, the choices for the binary mixtures are poorly predicted by the unique hue settings. Hue scaling was used to compare individual differences both within and between categories. Ratings for distant stimuli were again independent, while neighboring stimuli covaried and revealed clusters near the poles of the LvsM and SvsLM cardinal axes. While individual differences were large, mean focal choices for red, blue-green, yellow-green, and (to a lesser extent) purple fall near the cardinal axes, such that the cardinal axes roughly delineate the boundaries for blue vs. green and yellow vs. green categories. This suggests a weak tie between the cone-opponent axes and the structure of color appearance.
我们使用色调消除和焦点命名法来比较在为独特色调（如纯蓝或纯绿）和二元色调（如蓝绿色）选择的刺激中的个体差异。标准模型假设二元色调取决于红绿色和蓝黄色过程的成分反应。然而，独特色调和二元色调的方差相当，并且不同类别间的设置显示出几乎没有相关性。因此，二元混合色的选择很难通过独特色调设置来预测。使用色调缩放来比较类别内部和类别之间的个体差异。远距离刺激的评级再次相互独立，而相邻刺激则相互关联，并在LvsM和SvsLM主轴线的两极附近显示出聚类。虽然个体差异很大，但红色、蓝绿色、黄绿色以及（在较小程度上）紫色的平均焦点选择落在主轴线附近，因此主轴线大致划定了蓝色与绿色以及黄色与绿色类别的边界。这表明锥体对立轴与颜色外观结构之间的联系较弱。
