Color, an intuitive element affecting human senses, can adapt to the environment of a space, evoke emotional responses, trigger and accumulate visual experiences, and enhance the effectiveness of color in shaping spatial atmosphere and reinforcing spatial divisions. In the context of rapid urban underground space development, examining the rational application of color in underground parking spaces is crucial for improving guidance, comfort, and aesthetics. This exploration is essential for achieving high-quality development in urban underground parking environments. Based on color psychology and using typical cities in China as case studies, this paper develops a color analytical framework for urban underground parking spaces through the process of "color field investigation-analysis of color influencing factors-color system construction-color application and control" and proposes a detailed chromatographic scheme. Within this framework, color field investigation serves as the foundation for determining color usage. Key influencing factors for color selection include color elements and their relationships, the type of underground parking space, and public color perception demands. The color system has been constructed including safe colors, prohibited colors, and theme colors, which has been further divided into basic, auxiliary, and accent colors. This study provides a replicable and practical theoretical and applied framework for urban underground space management and urban color planning. The framework facilitates the establishment of a standardized color system and chromatographic scheme that aligns with urban aesthetics and public psychology, thereby improving development quality and supporting the high-quality development of urban underground spaces.
色彩，作为影响人类感官的直观元素，能够适应空间环境，引发情感反应，触发并积累视觉体验，增强色彩在塑造空间氛围和强化空间划分方面的效果。在城市地下空间快速发展的背景下，研究色彩在地下停车场的合理应用对于提升导向性、舒适性和美观性至关重要。这一探索对于实现城市地下停车环境的高质量发展必不可少。基于色彩心理学，并以中国典型城市为案例研究，本文通过“色彩实地调研—色彩影响因素分析—色彩体系构建—色彩应用与控制”的过程，构建了城市地下停车场的色彩分析框架，并提出了详细的色谱方案。在此框架内，色彩实地调研是确定色彩使用的基础。色彩选择的关键影响因素包括色彩元素及其关系、地下停车场类型以及公众色彩感知需求。已构建的色彩体系包括安全色、禁止色和主题色，进一步细分为基础色、辅助色和强调色。本研究为城市地下空间管理和城市色彩规划提供了可复制且实用的理论与应用框架。该框架有助于建立符合城市美学和公众心理的标准化色彩体系和色谱方案，从而提升发展质量，助力城市地下空间的高质量发展。
