描述了用于评估颜色变化的不同仪器方法。一组实验结果被用来测试各种公式的性能，并说明它们与视觉结果之间缺乏一致性。每种方法都基于不同的色差公式。公式之间的差异说明了绘制恒定AE轮廓为每个公式为各种色心。已经确定了公式彼此差异最大的颜色区域。在某些地区，方法之间的差异非常大，ΔE高达5倍，或两个完整的牢度等级。
Different instrumental methods for assessing change in colour are described. A set of experimental results were used to test the performance of the various formulae and to illustrate the lack of agreement between them and visual results. Each method is based on a different colour-difference formulae. The differences between the formulae are illustrated by plotting constant AE contours for each of the formulae for various colour centres. The areas of colour where the formulae differ most from each other have been identified. The differences between the methods in some areas were very large, up to a factor of five in terms of ΔE, or two full grades of fastness.
