使用熟悉物体的长时记忆颜色作为目标刺激，获得了12个对应的颜色数据集。在黑体轨迹上或附近的4种近中性光照条件下，收集了具有中性、红色、黄色、绿色和蓝色的常见物体的数据。结合其他更传统的非对称匹配技术，讨论了记忆配色方法的优点。将结果与文献中提供的8个相应的颜色数据集进行比较。使用相应的颜色数据来测试几个线性(von Kries、RLAB等)。和非线性(Hunt&Nayatani)色适应变换(CAT)。研究发现，一种简单的两步von Kries模型优于所有其他测试模型，其中记忆颜色集合和文学对应颜色集合的预测误差较低。预测误差大大小于普通观察者的标准不确定度，并与CIE u‘v’色度图中被认为仅可注意到的差异相当，支持使用基于记忆颜色的内部参考来研究颜色适应机制。
Twelve corresponding color data sets have been obtained using the long-term memory colors of familiar objects as target stimuli. Data were collected for familiar objects with neutral, red, yellow, green and blue hues under 4 approximately neutral illumination conditions on or near the blackbody locus. The advantages of the memory color matching method are discussed in light of other more traditional asymmetric matching techniques. Results were compared to eight corresponding color data sets available in literature. The corresponding color data was used to test several linear (von Kries, RLAB, etc.) and nonlinear (Hunt & Nayatani) chromatic adaptation transforms (CAT). It was found that a simple two-step von Kries, whereby the degree of adaptation D is optimized to minimize the DEu'v' prediction errors, outperformed all other tested models for both memory color and literature corresponding color sets, whereby prediction errors were lower for the memory color sets. The predictive errors were substantially smaller than the standard uncertainty on the average observer and were comparable to what are considered just-noticeable-differences in the CIE u'v' chromaticity diagram, supporting the use of memory color based internal references to study chromatic adaptation mechanisms.
