The decorative artistry of Southern Xinjiang residential doors, as a product of multicultural integration, features colors that not only exhibit distinct visual characteristics but also actively participate in the narrative construction of rural cultural tourism as symbolic elements. In the common color schemes of these doors—such as green, blue, yellow, white, and red—color functions in multiple dimensions: through symbolic narrative, it condenses regional cultural memory and natural metaphors; through structural narrative, it delineates spatial boundaries and rhythms, reinforcing the door’s role as a liminal threshold; and through emotional narrative, it creates atmospheric tones that guide emotional transitions, elevating the daily act of passing through the door into a ritualistic experience. Ultimately, as a symbolic construct, color transforms Southern Xinjiang residential doors from mere physical spaces into narrative spaces rich in cultural meaning and emotional depth.
