This paper describes the calculation of chromaticity difference. The text has been written specifically for the stain technologist and is largely self-contained. The concept of a uniform chromaticity scale (UCS) is described. A UCS is a diagram in which equal perceived differences in chromaticity are represented by equal distances anywhere on the diagram. UCSs are developed by transformations of the CIE 1931 chromaticity diagram, and may be linear (projective) or nonlinear. The effectiveness of the various transformations has been assessed using published data on discrimination of chromaticity. The usefulness of chromaticity difference calculations is illustrated by histological examples, including Romanowsky stained blood cells and Papanicolaou stained cells from the uterine cervix. Six UCSs are used in these examples, two projective and four nonlinear.
本文描述了色度差的计算方法。本文是专门为染色技术人员撰写的，内容基本完整。文中描述了均匀色度标度（UCS）的概念。UCS是一种图表，其中色度上相等的感知差异由图表上任何位置的相等距离表示。UCS是通过对CIE 1931色度图进行变换而得到的，可能是线性（投影）的或非线性的。已使用已发表的关于色度辨别力的数据评估了各种变换的有效性。通过组织学实例说明了色度差计算的实用性，包括罗曼诺夫斯基染色的血细胞和巴氏染色的子宫颈细胞。这些实例中使用了六种UCS，两种投影的和四种非线性的。
