Abstract: In the process of urban regeneration, color plays an important role in improving urban visual quality or showing urban styles and features. In this paper, University Ave which near the University of California, Berkeley was selected as the research object. The color information of street buildings was collected by Google Street View Image (GSV). The physical psychology method and M-S color coordination theory were applied to analyze the color quality and color harmony of buildings. The study applied a new method of street color analysis and evaluation, which has reference value for color planning and style control of small towns in China.
