Abstract

In this paper we discuss the procedure, performance and importance of chromatic analysis for preservation of historical architectural centre. We present the results of analysis of urban area and development of chromatic strategy for the Brazilian historical city of Piratini. Portuguese immigrants founded this city in the 18th century and it holds the most complete and homogeneous architectural setting in Rio Grande do SUI state. The purpose of the developed chromatic strategy is a creation of characteristic colour image (colour identity) of the historical centre adjusted to modem chromatic space of the city to assure a sustainability of historical architectural setting. Different palettes were prepared for the group of buildings with different levels of preservation. The elaborated proposals were approved by the state government and practice works are currently being executed. 1 Introduction In this work, we present the results of analysis of urban area and development of the chromatic strategy for the Brazilian historical city of Piratini.
