The main objective of this research is making sense of unity with urban environment and creation humanistic cities. Therefore in this survey various urban fields have been considered. The question that arises in this regard is that: “How is the relationship between color of the street furniture’s elements and the bed of the urban spaces where they are used?” Accordingly, this article is a step toward explaining the importance of the color and modality of its usage in street furniture, and also has developed a typical framework for designers using “descriptive-analytical” method and “documentary” research approach. In this study, Jameh mosque of YAZD’s avenue has been selected as a case study and through observation, filling questionnaire and field studies, information has been gathered. The Outcomes of this study has shown that factors such as functional, cultural, esthetic, ergonomic, emotional and environmental parameters affect the process of choosing color of the street furniture’s elements. As a result, providing a framework which can pluralize and summarize how to use colors and its features in the urban equipment is raised as a key issue of this paper. At the end, an approach based on Contextualism has been proposed for choosing color, better understanding and for experts in design and engineers in order to use in relative fields which is a try toward the targeted productivity in using color in the process of street furniture’s elements design.
