These paintings in comparison with original context have gradually changed in functions and materials according to the needs of the community and the new context.Also, given that metro stations are considered as public spaces; Their role is important for communication and interaction among people. Therefore, it is necessary to pay attention to the features of public art and to understand how they are perceived and efforts to bring their experiences closer to different citizens. Therefore, the factors influencing the perception and visual preferences of public art audiences can improve the perception process of these works. Such an understanding of the quality of space that hosts a public art work will also be affected. Visual quality is measurable from three dimensions: functional dimension: (readability), identity dimension: (beauty), semantic dimension: (meaning and message) that this article focuses on two dimensions of identity and meaning.
