The use of bright colors has entered the news in two unexpected ways this week. On Friday, Time’s Lightbox blog reported on the use of pink dye in the water cannons the government uses to fight political protesters in Uganda. The report included a stunning-looking—if dispiriting to think about—slide show demonstrating how the dyes, in a rainbow of colors, have been used elsewhere in recent decades. Today’s New York Times includes a story about the riotous colors—a “scourge” of tastelessness, according to some—used in the rebuilding of Baghdad. A slideshow accompanies the report.
