描述了一种定量比色法评估漆膜之间微小差异的方法。CIE 1976年推荐的CIE 1976色差公式已被证明具有实用价值，并被指定用于此应用。该原理基于CIE 1976颜色空间中测试样本和参考样本漆膜之间颜色、亮度、色度和色调差异的计算。如果采用规定的两种方法，可获得高光泽漆膜的可比结果。

Describes a method for the quantitative colorimetric evaluation of small differences between paint films. The CIE 1976 colour difference formula recommended in 1976 by the CIE has proved to be of practical value and is specified for this application. the principle is based on the calculation of differences in colour, lightness, chroma and hue between the paint films of a test specimen and a reference specimen in the CIE 1976 colour space. If the two methods specified are carried out, comparable results are obtained for high gloss paint films.
