When planning the color of municipal facilities, many cities often focus too much on whether the functions of the facilities meet the standards, but fail to fully consider whether the color of the facilities conforms to the local cultural characteristics and whether it is suitable for the needs of different scenarios. This ultimately leads to the color of some municipal facilities in the city not matching the surrounding natural environment and cultural atmosphere, and even appearing abrupt, becoming a factor that affects the overall beauty of streets and communities, and thus affecting the daily experience of residents. Based on this reality, the study focuses on the aesthetic issues in urban maintenance and renewal from the perspective of color aesthetics. The municipal facilities in Nagano Prefecture are selected as specific examples, with the aim of clarifying the significance of color aesthetics in the application of municipal facilities and finding ways to make the colors of municipal facilities meet practical needs while integrating into local culture and environment.
