Cool Hunting let us know about Let's Colour, a sort of international version of Publicolor. Let's Colour goes around the world painting drab walls bright colors (the project is sponsored by, you guessed it, a paint company.) Fernanda Romano, who works for Let's Colour, told Cool Hunting about the genesis of the project:
"let's find locations, places around the world, they're a bit dull, a bit grey. Let's engage the local community." She adds, encouraging community involvement was crucial to succeed: "Mandating things to people feels a bit old fashioned. People want to collaborate, people create content to share with the world."
