The colors on each petal of the official 22nd WCD logo-blue, red, yellow, white and black-represent the five cardinal colors of Korean traditional art. These colors were considered to be closely related to the five cardinal elements of um and yang: blue with wood, red with fire, yellow with earth, white with metal, and black with water.
These colors also played significant roles in traditional Korean culture and costumes. It was hoped that the use of the cardinal elements in the form of the five-color stripe on children’s sleeves would protect them from evil spirits. Other examples include the five-color stripe on the sleeves of the full court dress of queens and on the wedding garments of commoners throughout the Koryo and Chosun Dynasties. Regardless of personal taste, the five cardinal colors bore heavy symbolic value and deeply penetrated people’s lives and thoughts.
