意象研究是中国古代文学理论重点关注的基础问题，也是理解中国传统文化观念和审美范式的重要途径。为了更好的理解唐诗意象的构成特点，为唐诗意象研究提供具体的认识维度，本文基于唐诗文本中的丰富用色实践，从作为意象构成元素的色彩切入，将研究对象确立为唐诗中的赤青意象。赤青意象，具体来说是中国传统色彩体系下，含赤青色系颜色词的文化意象。考虑到色彩研究的特殊性，本文规划了光学属性和文化属性两条线索展开讨论。一方面，围绕赤青色系所具备的光学属性，本文从色彩的客观性出发，通过梳理色相、色象和意象之间的关系，将客观现象和主观认知通过“色象”概念串联在一起，通过具体样例归纳唐诗赤青意象反映明暗关系、动静状态、知觉体验的基本属性，以期挖掘唐诗中赤青色系的含彩意象的基本内涵，明确意象生成的前提要素。在此基础上，我们从认知层面进入文本创作层面，归纳了意象、意象群的演生和再造逻辑，并联系虚色等唐诗用色样例，说明了赤青意象对色相的超越。另一方面，围绕赤青色系所具备的文化属性，本文以“青衫”、“朱楼”等具体的赤青意象入手，以唐代的服色制度为切入点，进入唐代赤青色系的内部，梳理出深青乱紫、赤高于青等色彩文化现象，以期从更广阔的文化层面还原意象生成的时代背景，从而重新对唐诗赤青色系的内部权力等级结构进行说明。

The study of image is not only the basic issue of Chinese ancient literary theory, but also an important way to understand Chinese traditional cultural concepts and aesthetic paradigms. In order to get a better understanding of the constituent characteristics of Tang poetry images and provide specific cognitive dimensions for the study of Tang poetry images, based on the rich color practice in the text of Tang poetry, starting from the color as the constituent element of images, this paper establishes the research object as the red and cyan images in Tang Poetry. Red and cyan images, specifically, are cultural images containing red and cyan color words under the Chinese traditional color system. Considering the particularity of color research, this paper plans two clues: optical attribute and cultural attribute.On the one hand, focusing on the optical attributes of the red and cyan color system, starting from the objectivity of color, this paper combs the relationship between hue, color image and image, connects the objective phenomenon and subjective cognition through the concept of "color image", and summarizes the basic attributes of the red and cyan images in Tang poetry reflecting the relationship between light and shade, dynamic and static state and perceptual experience through specific examples, in order to excavate the basic connotation of the colorful image of the red and cyan color system in Tang poetry, Clarify the prerequisite elements of image generation. On this basis, we enter the text creation level from the cognitive level, summarize the evolution and reconstruction logic of images and image groups, and illustrate the transcendence of red and green images over hue by connecting the color examples of Tang poetry with virtual color and association. On the other hand, focusing on the cultural attributes of the red and cyan color system, this paper starts with the specific images such as "cyan shirt" and "red building", takes the clothing color system of the Tang Dynasty as the starting point, enters the interior of the red cyan color system of the Tang Dynasty, and combs out the color cultural phenomena such as dark cyan disorders purple, red higher than cyan, in order to restore the era background of image generation from a broader cultural level, So as to re explain the internal power hierarchical structure of the red and cyan color system of Tang poetry.
