The purpose of this study is to analyze the changing process of the theory on architectural color by Le Corbusier from his writings. The following is an analysis of the color theory by Le Corbusier; 1) It was found that the meaning of white had changed from the first term from being the absolute value, to become a relative value in the latter term. 2) He considered the material itself as color in the latter term. 3) The concept that the colors on earth were composed with four basic colors was consistent. In conclusion, we pointed out that such a changing process had a direct relation with his notion of environment.
