增强现实将虚拟物体叠加到真实环境中，使人类能够同时看到虚拟物体和真实环境。这种观看条件以及虚拟物体与真实环境之间的亮度关系给色彩外观表征带来了新的挑战。在这项研究中，构建了一个增强现实模拟器，人类观察者在不同的真实环境下将虚拟刺激的颜色外观调整为最白。在不同的适应相关色温（CCT）和适应亮度下产生最白外观的色度之间的总体差异与过去研究表面颜色和自发光显示器的研究相似，但发现适应CCT的影响较小。它表明，当观看增强现实图形产生的刺激时，色彩适应程度较低。
Augmented reality superimposes virtual objects onto a real environment, allowing humans to simultaneously see virtual objects and real environment. Such a viewing condition and the luminance relationship between virtual objects and real environments introduce new challenges in color appearance characterization. In this study, an augmented reality simulator was built and the human observers adjusted the color appearance of a virtual stimulus to the whitest under different real environments. The general differences between the chromaticities for producing the whitest appearance under different adapting correlated color temperature (CCT) and adapting luminance were similar to those in the past studies investigating surface colors and self‐luminous displays, but the effect of adapting CCT was found smaller. It suggested a lower degree of chromatic adaptation when viewing stimuli produced by an augmented reality graphic.
