A scientific approach in the recovery of the historic center of Rome: limits and potentialities of the “color plan”

The development of studies about conservation of historic centers has highlighted the importance of interventions on the color of the plastered facades. The study of a color plan in city centers has been the subject of numerous debates in Italy, particularly in complex cases such as the historic center of Rome. Over the past thirty years also the development of new products for the construction industry has introduced the problem of materials selection and evaluation of their compatibility in historic urban context. By a preliminary analysis of the current legislation it is clear only the definition of general precepts without giving clear rules for the restoration of plasters and colors. The aim of this study is to compare the results obtained from this survey with the current "Plan of protection of the urban image of Rome", to highlight the potentialities and limits of existing regulations and to better understand the tools to be used for the restoration of historic buildings.
