Reportedly, some chromatic adaptations have extremely short temporal properties, while others have rather long ones. We aimed to dynamically measure the transition of a neutral point as an aftereffect during chromatic adaptation to understand the temporal characteristics of chromatic adaptation. The peripheral retina was exposed to a yellow light to progress color adaptation, while the transition of a neutral point was measured at the fovea. In Experiment 1, the aftereffect had initially progressed but subsequently recovered despite ongoing chromatic adaptation and regardless of the retinal exposure size, suggesting that the adaptation mechanism at the cortical level continues to readjust the color appearance based on daylight conditions. Experiment 2 was similar to Experiment 1, except that it included participants of varying ages. Older eyes behaved in a homologous manner with younger eyes in Experiment 2, albeit quantitative differences. Regardless of age, similar recalibration of neutral points shifted by color adaptation suggests the color compensation function in older eyes may not change due to long-term chromatic adaptation by optical yellowing. In conclusion, the chromatic adaptation mechanism at the cortical level readjusts color perception, even in younger eyes, according to the daylight neutral point. This daylight information may be stored in the neural mechanism of color vision.

据报道，一些色彩适应具有极短的时间特性，而另一些则具有相当长的时间特性。我们旨在动态测量中性点的过渡作为色彩适应过程中的后遗症，以了解色彩适应的时间特征。周边视网膜暴露于黄光以促进颜色适应，而在中央凹处测量中性点的过渡。在实验 1 中，后效应最初有所进展，但随后恢复，尽管正在进行色彩适应并且无论视网膜暴露大小如何，这表明皮层水平的适应机制继续根据日光条件重新调整颜色外观。实验 2 与实验 1 相似，只是它包括不同年龄的参与者。在实验 2 中，年长的眼睛与年轻的眼睛表现出同源的方式，尽管存在数量上的差异。无论年龄大小，通过颜色适应改变的中性点的类似重新校准表明老年眼睛的颜色补偿功能可能不会因为光学泛黄的长期颜色适应而改变。总之，皮层水平的色彩适应机制根据日光中性点重新调整颜色感知，即使在年轻的眼睛中也是如此。这种日光信息可以存储在色觉的神经机制中。由颜色适应改变的中性点的类似重新校准表明，老年眼睛的颜色补偿功能可能不会因为光学泛黄的长期颜色适应而改变。总之，皮层水平的色彩适应机制根据日光中性点重新调整颜色感知，即使在年轻的眼睛中也是如此。这种日光信息可以存储在色觉的神经机制中。由颜色适应改变的中性点的类似重新校准表明，老年眼睛的颜色补偿功能可能不会因为光学泛黄的长期颜色适应而改变。总之，皮层水平的色彩适应机制根据日光中性点重新调整颜色感知，即使在年轻的眼睛中也是如此。这种日光信息可以存储在色觉的神经机制中。
