色彩作为最显著的视觉要素，在礼制中扮演了重要的角色，本文试图以《步辇图》色彩为个案，希望揭示唐代社会 的等级制度、文化交融、日常婚姻，为我们理解唐代的礼制精神如何体现在具体的礼仪场合提供了重要依据。《步辇图》构 图遵循 “右为尊、左为次” 的礼制规范，分为左右两部分，右边部分为唐太宗（至尊黄色），左边部分按照等级依次为礼 部官员（三品绯色）、禄东赞（本国礼服）、翻译（无品白色）。身着本国礼服的禄东赞体现唐代官方奉行“自古皆贵中华， 贱夷狄，朕独爱之如一”的文化融合政策。婚姻作为人伦大礼，唐代人将其理解为天地阴阳的基本内容，并在色彩上加以运用。

Color, as the most prominent visual element, has played an important role ritual system. This article attempts to use the color in the painting "Walking Chariots" as a case study, hoping to reveal the hierarchical system, cultural integration, and daily marriage of Tang Dynasty society, and help us understand how the spirit of Tang Dynasty's ritual system was reflected in specific ceremonial occasions. The "Walking Chariot Diagram" is divided into two parts, the right part is large, the left part is small, and the right part is Emperor Taizong of Tang (supreme yellow); On the left side, in order of rank, there are officials from the Ministry of Rites (third grade crimson), Ludongzan (national dress), and translators (no grade white). Lu Dongzan, dressed in his own country's formal attire, expressed the cultural integration policy of the Tang Dynasty's official policy of "valuing China since ancient times, belittling barbarians, and loving them as one". Marriage, as a great ritual of human relations, was understood by Tang Dynasty people as the basic content of yin and yang in heaven and earth, and was used in color.
