In the visual design of a portal website, color is the first intuitive factor for users. It is relatively difficult for the designer of a city portal website to choose a color system that represents a city’s unique color from among the many available options. Therefore, this study extracted a decision-making model of the urban color system, which can help decision-makers and designers choose among color systems, and then effectively design a portal website that conforms to local cultural attributes. The proposed method to solve the problem involved obtaining optimal color matching by performing weight analysis of colors through 123 sample color semantics, factor analysis, and a fuzzy analytic hierarchy process. Semantic analysis was used to classify colors into four categories of fashion, technology, calm, and dazzling. The fashion color matching scheme scored relatively high. Web page color matching schemes with a white background were popular, among which a white and green color matching scheme scored relatively high. At the same time, there are differences in color preferences between genders and cultures. This study is significant because it proposes a color decision model for portal websites, which provides a reference value that can also be applied to the selection of color schemes for other types of web pages in the future.在门户网站的视觉设计中，色彩是用户感知的首个直观要素。城市门户网站的设计者往往难以从海量可选方案中，遴选能够彰显城市独特色彩调性的色彩体系。为此，本研究构建了城市色彩体系决策模型，可辅助决策者与设计者筛选适配的色彩方案，进而高效设计出契合本土文化属性的门户网站。本研究提出的解决方案通过123组样本色彩语义权重分析、因子分析以及模糊层次分析法，对色彩进行权重赋值以得到最优色彩搭配方案。通过语义分析将色彩划分为时尚、科技、沉稳、炫丽四大类别。其中时尚类色彩搭配方案得分相对较高；以白色为底色的网页色彩搭配方案广受青睐，白绿配色方案得分尤为突出。同时，不同性别与文化背景的群体在色彩偏好上存在显著差异。本研究的价值在于提出了门户网站色彩决策模型，可为相关工作提供参考，且该模型未来亦可推广应用于其他类型网页的色彩方案遴选。
