These photos are amazing! I love this public color movement! The Let's Colour Project and another project called Favela Painting. Favela is the Brazilian Portuguese word for slum. Jeroen Koolhaas and Dre Urhahn are the artists behind the Favela Painting (the duo goes by Haas&Hahn). Above is the central square of a favela in the heart of Rio de Janeiro. The Let's Colour Project (so far) is in the following countries: Turkey, Brazil, France, India and the UK.
