人们普遍认为,颜色可以分解成少量的颜色成分。特别地,每个色调都可以被描述为一组有限的分量色调的组合。方法,如颜色命名和色调缩放,旨在描述颜色的相对数量的组成色调。然而,在组分色调的命名上没有共识。此外,色调(更不用说分量色调)的概念通常是口头定义的,而不是感知的。在本文中,我们试图操作这样一个基本属性的颜色色调不使用的口头条款。具体来说,我们提出了一种新的方法-部分色调匹配-这是基于判断两个颜色是否有一些共同的色调。它允许客观地建立一组组成色调,而无需诉诸于口头定义。具体而言,最大的颜色刺激集,所有这些部分匹配彼此(称为色度类),可以从观察者的部分色调匹配。一个色度类别被证明是由所有的颜色刺激,包含一个特定的分量色调。因此,色度类别完全定义了分量色调的集合。使用孟塞尔纸的样本,进行了一些实验,部分色调匹配与12个没有经验的正常三色观察者。结果加强了四个组成色调(黄色,蓝色,红色和绿色)的经典概念。黑色和白色(但不是灰色)也被发现是组成颜色。
It is widely believed that color can be decomposed into a small number of component colors. Particularly, each hue can be described as a combination of a restricted set of component hues. Methods, such as color naming and hue scaling, aim at describing color in terms of the relative amount of the component hues. However, there is no consensus on the nomenclature of component hues. Moreover, the very notion of hue (not to mention component hue) is usually defined verbally rather than perceptually. In this paper, we make an attempt to operationalize such a fundamental attribute of color as hue without the use of verbal terms. Specifically, we put forth a new method—partial hue-matching—that is based on judgments of whether two colors have some hue in common. It allows a set of component hues to be established objectively, without resorting to verbal definitions. Specifically, the largest sets of color stimuli, all of which partially match each other (referred to as chromaticity classes), can be derived from the observer's partial hue-matches. A chromaticity class proves to consist of all color stimuli that contain a particular component hue. Thus, the chromaticity classes fully define the set of component hues. Using samples of Munsell papers, a few experiments on partial hue-matching were carried out with twelve inexperienced normal trichromatic observers. The results reinforce the classical notion of four component hues (yellow, blue, red, and green). Black and white (but not gray) were also found to be component colors.
