In this project, designers extracted the recommended urban color spectrum from Nanchang's landscape environment and historical culture, then applied the urban color spectrum to key sections such as waterfront and mountainous areas, and designed building facade, bridge and pedestrian overpass‘s color image in combination with their reform projects. Designers are committed to exploring the color gene of Nanchang's traditional culture and natural environment, and deriving and innovatively applying it to the urban space of key sections, so as to create color environment with local significance.
