Sino-Singapore Guangzhou Knowledge City is a state-level high-tech city jointly built by the Chinese and Singapore governments. We are commissioned to design the color image of Knowledge City. We extracted and established the recommended color spectrum of "The clear and bright sunshine tones" and apply this set of color spectrum to the design of pedestrian corridor path, combining the form of corridors in different sections and the users, to carry out the color design of the corridors and ground pavement?so as to create a symbolic spatial image of the Sino-Singapore Guangzhou Knowledge City.
