Famous architectures in urban contexts: the impact of colours and materials

Architecture is not just a container or a place in which it is possible to perform functions; architecture is everything that surrounds us, it is the space in which we immerse ourselves and with which we communicate. It is not the shape of the project that first influences our perception of space, whether it is open or closed, but the colours and materials that characterise and define it, making it harmonious and pleasant or, in the opposite way, hostile and inhospitable. In 1981 the UNI 8289:1981 "Construction. Needs of the final user. Classification" defined the term "well-being" as "the set of conditions relating to states of the building system appropriate to life, to health, to the performance of the users' activities", how do colours and materials contribute to the conditions of well-being? Which are the targets that can be achieved through the wise use of these elements? The aim of this work is to analyse the application of colours and materials in famous architectures in order to determinate the impact at urban and human level, how they dialogue with the context and how they dialogue with human perceptions, identifying three directions of intervention: colour and materials as anthropomorphic relation, colours and materials as pictorial support, colour and materials as function.
