ABSTRACT=In this study, a new quantifiable and refined urban street color analysis method was proposed by combining professional color cards and efficient software color recognition, which solved the problems of low efficiency and difficulty in the quantification of urban color research and analysis. The research mainly uses CBCC (China Building Color Card) and Python（use programs for HSV color segmentation of pictures）and other software to carry out color recognition for a street view. From the aspects of color composition, type, proportion, visual level, and color sequence of street facade, this paper makes a quantitative analysis of the color of Avenida de Almeida Ribeiro in Macao from multiple angles. The method of combining color card colorimetry with computer color recognition, which not only considers the inherent color of the building but also includes the color situation under the influence of the environment, can express the "actual color situation" of the building more completely. This paper quantifies, combs, summarizes and compares architectural color and environmental color completely. This method has good universality and ease of use in practice, and the conclusion of the study can provide a reference for the color planning of Macao, the color selection of urban renewal has reference significance, and provide a new method for the study of urban color.
