The purpose of this study was to develop a fashion image color analysis program to more precisely and accurately analyze colors found in fashion to be able to reproduce them more accurately. After extracting the information elements that were necessary to design a user interface as determined by the research method, the elements were classified and the color analysis design sequence was completed. The user interface screen was designed based on the color analysis sequence design. An algorithm was developed to be used in the program based on the detailed information structure. The fashion color analysis program was designed to be easy to use even for first-time users. It was implemented using C++ and MFC in the Visual Studio 2015 environment. Program reliability was evaluated using the developed program. The program was written in Korean and English and the program and the user manual were made available on the Naver blog.
