为了测试不同颜色匹配函数的预测性能, 基于灰色、 棕色、 紫色和蓝色4个目标色, 共制作了16对近同色异谱色样对(围绕每个目标色分别制作了4个待比较色), 组织14名年龄不同的色觉正常观察者基于心理物理实验方法中的比较法, 开展了色差大小比较实验。 结果表明, 实验组织的老年观察者的锥细胞响应较年轻观察者有所下降, CIE1931的预测性能优于CIE1964。 不同颜色区域, 各颜色匹配函数的表现各异, 在进行某些颜色(如灰色, 紫色和蓝色)区域的色度值表征和色差评估时, 即便观察视场角大于4°, CIE1931的计算性能仍然优于CIE1964。 现有CIE2006匹配函数考虑到晶状体光谱透光率和中央凹的锥细胞光谱响应, 下一步可继续强化中央凹锥细胞光谱响应, 优化其计算性能。

In order to test the performances of different color matching functions, 16 pairs of nearly metamerism color patches based on gray, brown, purple and blue were prepared, and 14 observers with normal color vision were organized to compare the color difference with the psychological method of comparison. The results indicated that the spectral response of the older observers will decrease and the performance of the CIE1931 outperform the CIE1964. In different color regions, the color matching functions have different performances. For the description and assessment of gray, purple and blue colors, even though the viewing fields is larger than 4°, the performance of the CIE1931 still outperforms the CIE1964. The existing CIE2006, which considering the eye-lens and macular pigment optical density variations, have been improved than the CIE1931 and CIE1964.The further work can intensify the macular pigment optical density for the accuracy improvement compared with the visual response.
