Color, as a symbol system with cultural depth and visual guidance, not only plays an aesthetic role in digital animation, but also carries multiple values of emotional transmission and identity recognition. With the increasing shift of urban cultural dissemination towards digital media, how to construct concrete regional images through color has become an important issue in the visual construction of humanistic spaces.
