As we know, among the main criteria for using urban furniture are regional divisions, urban elements, type of architecture and local texture. It is natural that from the point of view of regional divisions, more factors such as special characteristics of the region in terms of climate and climate, as well as cultural characteristics, have an impact on determining urban furniture, traffic signs, etc. Also, the choice of color from the perspective of urban psychology and the classification of citizenship needs based on the culture of each region, the color of appliances used in green space, the coordination of natural colors in green space with the surrounding landscape, etc. is effective.
In addition to the color of the equipment, the space intended for their placement also has great potential for color composition. Color recognition in urban space depends on factors such as viewing time, background colors, solid colors, and natural light. Red and orange are usually the most prominent colors. The rays emitted by these colors affect the focus of the human eye lens and cause farsightedness when detected. But green and blue, on the other hand, make the eye closer, because these two colors induce depth. Yellow and purple as neutral colors, when watching, do not cause either the camera or myopia.
Determining the color of urban furniture equipment should be an indicator of its environment but avoid visual disturbance.
