老年人所看到的颜色外观与年轻人所看到的颜色外观没有显著差异，尽管他们的晶状体随着年龄的增长而变得更黄。我们计算了蒙塞尔彩色芯片反射到视网膜上的光与年龄相关的变化，得出的结果表明，所有彩色芯片的色度值都移到了xy色度图的黄色区域。然而，对CIELAB图的重新绘制和von Kries适应模型的估计表明，老年人可能使用一般的颜色适应过程来补偿他们的色觉。为了验证这一假设，我们进行了两个实验：色彩适应实验和色彩匹配实验，以模拟老年人看到的d65光，但使用年轻的受试者。结果表明，颜色适应并不能完全解释老年人的颜色补偿，提示与年龄相关的黄蓝对手色机制的变化可能有助于这种补偿。
Color appearance seen by old people does not significantly differ from that seen by young subjects even though their ocular lens has become more yellow with age. We calculated the age-related change of lights reflected from Munsell color chips onto the retina, and derived results that show that the chromaticity values of all the color chips shifted to the yellow region of the xy-chromaticity diagram. However, a replot on the CIELAB diagram and the estimation by means of the von Kries adaptation model suggests that old people may compensate their color vision using a general chromatic adaptation process. To test this hypothesis, we conducted two experiments: a chromatic adaptation experiment and a color matching experiment to simulate D65-lights as seen by older people but using young subjects. The results indicate that chromatic adaptation does not provide a complete explanation for color compensation by older people, suggesting that an age-related change of the yellow-blue opponent color mechanism may contribute to this compensation.
