This study was conducted to analyze the research and process of school environment color design through documented works and actual projects, understanding it as a series of phenomena, and developing theories from it. As a researcher, the study was an attempt to identify the problems regarding the color design methods and how those problems have evolved, as well as to interpret the meanings that can be derived from them. The study utilized a grounded theory method of describing the situation that resulted from the user-participating project, creatively analyzing the collected information and survey responses from the workshop, and therefore deriving a theory from it. Color preference is a key factor that enables a fast and easy way to understand user characteristics. But applying preferred colors to school colors, expressing the desired school image with colors, and extracting colors from the surrounding environment should no longer be important clues for school color design. ‘Good design’ should be a creative activity that utilizes such clues to express unfamiliar concepts as refined and dignified designs. Although there is no perfect design that can satisfy “everyone”, designers have to aim to elicit 'Good taste' and create 'Good design'. As the long-lasted concept of school as a physical facility for education is dramatically changing today, there is a need for continuous research on developing reasonable and creative methodologies to derive a better educational environment.
