Color fusion is an extremely important part in the reconstruction design of historic and cultural blocks in the process of China's urban historic and cultural blocks transformation. Based on the deep learning algorithm, this paper constructs the color analysis model of cultural blocks, uses the multiscale feature semantic segmentation algorithm analysis technology of dual channel fusion for color research, extracts and analyzes the color of historic and cultural blocks, thus establishes its color fusion model, analyzes the color defects of Tianzifang historic and cultural scenic spot, and proposes to use plants, buildings and pavements to improve the color fusion degree of Shikumen cultural blocks.

THE PRESENT SITUATION OF COLOR COMPOSITION OF HISTORIC AND CULTURAL BLOCKS IN SHANGHAI
The importance of color in historic and cultural blocksThe emergence of new materials and technologies has impacted the original construction mode and urban texture of historic and cultural blocks.The architectural color of historic and cultural blocks is an important and relatively stable historic product under the natural conditions and cultural traditions in a specific region. It most directly reflects the characteristics of the blocks that are different from the landscape of other regions. It is an indispensable element in the protection of historic and cultural blocks. The blind worship of international architectural style makes people lose the original cultural memory of the city, lose control over the color style and order, and gradually fall into a loss. Although people have realized the importance of color elements in the protection of historic and cultural blocks to a certain extent, due to the lack of standardized and scientific method guidance, the protectors do not know how to scientifically investigate and study the color of block buildings and make feature extraction, and do not know how to reasonably formulate color protection measures. Therefore, to clarify the architectural color is to grasp the keynote of the historic and cultural blocks. The analysis and study of architectural color will help to provide scientific guiding methods and theoretical basis for the protection of historic and cultural blocks.
Color elements of historic and cultural blocksAccording to the many factors that affect the landscape color style in the historic and cultural blocks, the vertical elements of the landscape color style are divided into six parts: building body, landscape greening, pavement, public facilities, plaque advertising and traffic facilities. Among them,
