There's been an increasing number of urban projects breaking out the paint brushes as a low-cost means of improving cities. As stated by Jaime Lerner, former Mayor of Curitiba, for every zero that is removed from a city budget, the more creative solutions become. It seems these examples represent areas with extremely limited budgets. Object Orange is a public art project in Detroit that is calling attention to blighted structures through the use of bright orange paint. It seems their efforts have resulted in their desired outcome - increased demolition of unsafe structures.
