Jeju´s logo for the 21st century free international city symbolizes the clean natural environment and future-oriented image expressed in simple brush strokes. The clean natural environment is Jeju´s pride and valuable asset that the world recognizes and that we have to cherish. The horizontal brush stroke stands for Jeju´s equal spirit. With black symbolizing basalt as a base, green stands for green Mt. Halla and natural environment, blue for seas harboring limitless resources and orange symbolizes hope, peace, and the will of future-oriented people of Jeju. The logo, that looks soft and rough at the same time, expresses flexible and simple Jeju culture and embodies the features of Jeju people who work hard toward the future.
