Colors and shapes that regulate the flow of children and teachers and ensure their safety, cycle paths painted in one night, an asphalt area that becomes a meeting place for paints. These are the micro interventions, the so-called Tactical Urbanism / Soft Urbanism, that make the city more beautiful and clean. It will be discussed on April 16 in a video conference organized by Noroo Milan Design Studio, the Colorful Intelligence that deals with color consultancy and design, in collaboration with WAU! Milan, a voluntary association that since 2006 collaborates with those who share the vision of a participatory city where everyone contributes to the improvement of a place.
