Abstract: Urban colour plays a vital and multifaceted role in shaping the urban landscape. Beyond its visual appeal, it reflects cultural heritage and social development. This paper explores three core questions through a detailed bibliometric review of 50 urban colour studies published between 2008 and 2025. The study approaches the topic from various perspectives of urban development. The first part of the study explores the structure of urban colour, distinguishing between hues derived from the natural environment and those produced by human activities. It highlights how these elements interact to influence the overall atmosphere of the city. The second part focuses on cultural influences, examining how tradition, religion, and local history influence colour choices and express community identity. The third part explores ways to encourage wider public participation in colour planning, highlighting the role of consultation, education, and digital platforms in reflecting local preferences and values. In summary, urban colour is not just about aesthetics—it is also a vehicle for cultural expression, community solidarity, and quality of life. A deeper understanding of how natural, built, and cultural elements intersect can help build more vibrant and inclusive urban spaces. Future research should continue to explore these dynamics to support forward-looking planning practices.
