the control of color in architecture is measured according to the visibility cursors in the built landscape. The final perception of an architecture is appreciated in relation to its immediate environment, between integration and contrast of the construction. Whether it is old architecture, historical, heritage where the color is induced by the use and respect of materials highlighted for their intrinsic chromatic qualities (stone, brick, wood, metal, terracotta…) or whether it is a question of the use of the color of the building or in contemporary architecture, with a more assertive chromatic expression and in which color is entrusted with new missions (identification, signage…), a3dc intervenes in addition to the work of architects commissioned for global programs of color, from facades to interior spaces and circulation.
