The urban color design of Kashgar is a scientific practice concerning environmental adaptation, identity, cultural inheritance, and future imagination, as well as a visual manifesto imbued with sunlight reflection, sandstorm imprints, and historical memories. Extracting color genes from Kashgar's natural environment, historical culture, ethnic art, and architectural features, we established a recommended color spectrum composed of four major color systems: "Populus euphratica gold, terracotta red, glacier green, and clear-sky blue." These colors are applied to the city's public spaces, buildings, and signage systems, creating a unique urban color image system of Kashgar with the imagery of "golden warm sand and starry turquoise blue." Especially in the renewal design of five key streets, color design schemes are customized based on the "sunlight-color response curve" to adapt colors to the climatic environment and shape urban spaces with colors. By establishing a symbolic urban color system for Kashgar, we use the language of colors to tell the story of Kashgar's sunshine, sandstorms, history, and future.
