Color polymorphism is an interesting property of chemical systems which present crystal polymorphs of different colors. It is a rare phenomenon, with only a few examples reported in the literature hitherto. Nevertheless, systems exhibiting color polymorphism have many potential applications in different domains, such as pigment, sensor, and technology industries. Here, known representative chemical systems showing color polymorphism are reviewed, and the reasons for them to present such property discussed. Also, since some of the concepts related to color polymorphism have been frequently used imprecisely in the scientific literature, this article provides concise, systematic definitions for these concepts.
颜色多晶型现象是化学系统的一种有趣特性，该系统呈现出不同颜色的晶体多晶型物。这是一种罕见的现象，迄今为止文献中仅报道了少数几个例子。然而，表现出颜色多晶型现象的系统在不同领域有许多潜在应用，如颜料、传感器和技术产业。在此，对已知的呈现颜色多晶型现象的代表性化学系统进行综述，并讨论它们呈现这种特性的原因。此外，由于与颜色多晶型现象相关的一些概念在科学文献中经常被不准确地使用，本文为这些概念提供了简洁、系统的定义。
