Architectural colors should be constructed from the 6 aspects, namely, conveying city spirit, coordinating the environment, showing regional characteristics, reflecting public concept, obtaining public sympathy, combining cultural connotations of color and functions of space. Moreover, the impact of regional culture on architectural color should be properly handled, the emotions of architecture for the city reflected on the surface of architecture, which can reverse the convergence of city images to some extent, and promote the diversity of regional humanistic architectural landscapes.展开更多
