A 64 year-old man in Istanbul decided to brighten the neighborhood by painting rainbow colors on some wide, gray, crumbling stairs. When municipal officials sent workers after nightfall to hurriedly repaint the steps gray, a quiet revolution started on Twitter. Not only did volunteers come out to repaint those stairs that Huseyin Cetinel had spent hundreds of dollars on, they painted other stairs and walkways in cities around Turkey, posting photos on social media. A Pandora’s Box of color had unwittingly been opened.
