我们介绍了一种新的技术来描述色彩外观中的色调含量。与经典的颜色匹配（这意味着颜色刺激的视觉等效）相比，部分颜色匹配意味着两种颜色的刺激可能不同（彼此不匹配），但可能有一些共同的色调。当比较粉红色和橙子刺激时，三色观察者可以在两者中看到一些红色色调。或者，红色和绿色是互补的，甚至不部分匹配，因为它们没有共同的色调。我们使用20个孟塞尔芯片的样本进行了一项实验，要求观察者判断每对芯片是否存在部分颜色匹配。一个部分颜色匹配矩阵被用来推导出一套组件色调的观察者在他们的决策过程中使用。结果加强了四个独特的色调的经典概念。然而，必须指出的是，这些结果是在没有诉诸语言分类或独特色调知识的情况下获得的。这可能是至关重要的，利用该技术在检查儿童和受试者的色觉异常。
We introduce a new technique to describe hue content in colour appearance. In contrast with classical colour matching, which implies visual equivalence of colour stimuli, partial colour matching means that two coloured stimuli may be different (do not match each other) but may have some hue in common. When comparing a pink and an orange stimulus a trichromatic observer can see some red hue in both. Alternatively, red and green, being complementary, do not even partially match as they have no common hue. Using a sample of twenty Munsell chips, we carried out an experiment asking observers to decide if a partial colour match exists for every pair of chips. A partial colour matching matrix was used to derive the set of component hues which the observer used in their decision making process. The results reinforce the classical notion of four unique hues. It must be said, however, that the results were obtained without resorting to verbal categorisation or knowledge of unique hues. This maybe crucial for making use of the technique in the examination of children and subjects with colour vision abnormalities.
