The purpose of this study was to extract the characteristics of color usage and of collective housing in Germany with an emphasis on rationality, functionality, and connectivity. The methodology was to study four residential complexes: Kichsteigfeld near Potsdam, Tegel near Berlin, and Kichrode and Pelikan Viertel near Hanover in Germany. The analysis of color usage was based on “form,” “landscape,” “user,” “material,” “resident,” “policy,” etc. As a result of the study, first, four unified palettes with characteristics unique to the region were applied, and palettes including a basic color with small changes in color were used. Second, color was applied in a way that maintained simple form. Simple form maintenance was ensured through color matching of basic form and architectural elements. Third, a stable and pleasant residential environment image was maintained despite the use of various colors due to repeated and cross use of casting colors and auxiliary colors applied to the interior and exterior of all collective dwellings and public facilities. Fourth, the method of applying paint on the concrete surface occupied most of the time, and the color by the material was hardly used. Fifth, I could not find the location, name, signs, or decorative or intimacy graphics. Finally, the color of the building maintained a stable and pleasant residential environment due to the color matching the fences, outdoor common facilities, garages, and shared space. The results of this study are expected to be used as reference material for the planning and type calculation of settlement housing by understanding the relationship between color and form from the planning stage, together with the usage of collective housing color.
