在第二部分中，描述了NCS的某些属性和应用。定义了视觉亮度的颜色辨别视觉参数，并引入了一个由经验数据导出的公式，可操作地将边界清晰度（GT）定义为对比度和视觉易读性的表达。提出了一个模型细分的空间分割成段显示感知字符般的颜色类别，在每个类别中，所有的颜色共享的特性，具有相同的基本颜色作为主要属性和相同的次要属性。进一步讨论，所谓的二进制属性的感知存在的概率，指的是颜色感知，其中的质量是由两个基本属性（如灰色）的同时感知表示。John Wiley & Sons，Inc.
In this second part, certain attributes and applications of the NCS are described. The color discriminative visual parameter of visual lightness is defined, and an equation is introduced derived from empirical data that operationally define distinctness of border (GT) as an expression of contrast and visual legibility. A model is proposed for a subdivision of the space into segments showing perceptually character-like color categories, within each of which, all colors share the characteristic of having the same elementary colors as main attributes and the same secondary attributes. Further is discussed, the probability of the perceptual existence of what is called binary attributes, referring to color percepts in which the qualities are represented by the simultaneous perception of two elementary attributes (as in grey). © 1996 John Wiley & Sons, Inc.
