Il colore nell’architettura storica della Sardegna: linguaggi e significati

The color, in its valences of language and meaning, is a topic not sufficiently considered in the vast and complex landscape of the settlements in Sardinia. A careful reading of studies made on historic Sardinian towns, following the line of studies of M. Le Lannou (1941) and O. Baldacci (1952), shows that investigation emphasizes the origins of urban spaces and housing typologies using standard parameters that consider the morphological appearance, the size and the distribution, often neglecting the color. Studying the architecture and the urban centers, often tend to ignore the color, which track a creative act in its multiple meanings (historical, cultural, perceptual), is an essential component of the architecture and of the built space, in all different scales of perception. Important cultural component in the configuration of the living space, color features and distinguishes different geographical areas of Sardinia. Through this study, we want to investigate the "regions of color" as an historical and environmental value. The color and the material components of the historic facades of the buildings show the first expression of the cultural identity of the different geographical sub-regions of Sardinia. The recognition and the cultural belonging are expressed using different techniques and different materials of local tradition, going to affect the whole town was built by determining the identifiability of the place. Interested in the colors of the historic architecture, it's responding to the need to reclaim the sites, identifying the color tones that still feature some traditional types and over time that have shaped the image and memory of the "built landscape". In this study, the analysis refers to certain urban areas of Sardinia, centers selected as sample for their specific evocative character. The research aims to survey the material evidence which still persist and are worthy of study, with a view to establish a repository of information on the color of the "historical space" in some cities and several villages. The analysis on the color of the urban built, stands out today in Sardinia as an urgent problem to be addressed in order to give identity to the chaotic urban areas attacked by colors: various design styles of contemporary architecture have enabled new models of color, who are opposed and dissonant compared to the traditional colors of the historic buildings. The colors of the "built environment" affected by the absence of careful planning which defines a "use of color" as an expression of order and of a collective psychological need. It is necessary to reactivate a congruence between architectural languages and meanings associated with them, through a general rule of color coordination and monitoring for the future changes in the urban scene.
