Light sources have similar effects on different object colors, as shown by multiple pairs of arrows in Figure 8. Similarly, it can be deduced that the chromaticity coordinates of the light source should be on the intersection of the above lines. WebGrassmann引入了另一个重要概念： 色匹配（color matching） ， 指物理上不同的两束光在主观上看起来是一样的（也被叫做同色异谱metamerism） 传递定律: 对于任意光a,b和c, 如果a与b匹配 , b与c匹配 , 那么a与c匹配 …

Grassmann's law, named after its discoverer Hermann Grassmann, is a dissimilatory phonological process in Ancient Greek and Sanskrit which states that if an aspirated consonant is followed by another aspirated consonant in the next syllable, the first one loses the aspiration. The descriptive version was given for Sanskrit by Pāṇini. Here are some examples in Greek of the effects of Grassmann's law: WebPara fundamentar la teoría, Grassmann propuso considerar como términos básicos tres atributos perceptuales del color: Tono (Farbenton).
