Color matching functions (CMFs), which are used to derive tristimulus values and chromaticities, play a very important role in color characterization, calibration, and specifications. Great efforts have been made to investigate how CMFs can characterize the color matches and mismatches between stimuli with different spectral compositions under different sizes of field of view (FOV). Few study specifically investigated how to better characterize the CMFs for different observer ages. In this study, we carefully designed a series of color stimuli using different CMFs based on our two past studies, and asked 51 young, middle-aged, and senior observers to evaluate the color differences. The three sets of CIE 2006 CMFs (i.e., 10°, 4°, and 2°) with an age of 20-, 40-, and 70-year were found to characterize the perceived color differences for the young, middle-aged, and senior observers. In addition, it was found that the characterization of a group of observers can also be performed using these three sets of CMFs based on the distributions of the observers, which had a better correlation to the perceived color differences than the individual colorimetric model.
用于推导三刺激值和色度的颜色匹配函数（CMF）在颜色表征、校准和规格制定中起着非常重要的作用。人们已经做出了巨大努力来研究CMF如何表征不同视场（FOV）大小下具有不同光谱组成的刺激之间的颜色匹配和不匹配。很少有研究专门探讨如何更好地表征不同观察者年龄的CMF。在本研究中，我们基于之前的两项研究，精心设计了一系列使用不同CMF的颜色刺激，并让51名年轻、中年和老年观察者评估颜色差异。结果发现，三组20岁、40岁和70岁的CIE 2006 CMF（即10°、4°和2°）能够表征年轻、中年和老年观察者感知到的颜色差异。此外，还发现基于观察者的分布，使用这三组CMF也可以对一组观察者进行表征，与个体色度模型相比，这与感知到的颜色差异具有更好的相关性。
