Inclusive design strategies based on a human factors perspective: integrating urban color in the regional cultural diversity of multi-ethnic cities

Abstract: The national culture of a city is a symbol of its unique identity, which profoundly affects the residents' sense of identity and belonging. Colour, as a visual expression of urban cultural landscape, not only shapes the visual image of the city, but also guides the residents' emotional experience and behavioural patterns in an invisible way. With the rapid development of cities, the phenomenon of serious loss of urban characteristics and one-sidedness of a thousand cities has become more and more prominent. This poses a challenge to the psychological feelings of urban residents and the diversity of social culture. Through the collection and research of ethnic colours in Hohhot City, it is found that how to make the city colours can reflect the cultural characteristics of multi-ethnic integration, and at the same time meet the psychological needs and aesthetic preferences of the residents, is a problem that needs to be solved by the current urban colour planning. This thesis aims to study the development profile of Hohhot and extract the current status of urban colour through literature, questionnaire survey, field research, etc., and quantitatively analyse the colour information by using the NCS colour system and the self-developed Java NCS colour analysis data program to determine the overall positioning of urban colour in Hohhot. In the planning process, we fully consider the human factor, from the residents' emotional experience, cognitive habits and behavioural patterns, and combine the urban colour planning with the city's functional layout, architectural style, landscape design, etc., to form a colour planning system from macro to micro, and from general to specific. Through the research method and based on the research of multi-ethnic urban architectural planning, the regional urban colour characteristics of Hohhot are finally summarized. The results of the study analyzed the minority architectural colours in the main urban area of Hohhot and obtained the chromatogram of the ethnic city of Hohhot, which is composed of greenish grey, light grey, white and other colours, from the grey landscape area in the western part with low luminance and low purity to the light grey landscape area in the eastern part with high luminance and low purity, which forms the rhythmic change of the urban colours in luminance and purity, which not only conforms to the aesthetic preference of the residents, but also can be used psychologically and psychologically. These colours not only meet the residents' aesthetic preferences, but also give them a sense of tranquility, comfort and belonging psychologically. Urban colour planning from the perspective of human factors can not only shape the unique image of the city, but also improve the quality of life of the residents and social and cultural diversity. In the future urban development, we should pay more attention to the combination of national cultural characteristics and modernism elements, to achieve the organic integration of traditional national culture and modern urban culture and innovative development, to provide urban residents with a more colorful and culturally rich urban colour environment.
