“Fans of Ota’s running man point to two key advantages: It’s a pictogram, and it’s green. The sign’s wordlessness means it can be understood even by people who don’t speak the local language. And the green color, they argue, just makes sense. Green is the color of safety, a color that means go the world over. Red, on the other hand, most often means danger, alert, halt, please don’t touch. Why confuse panicked evacuees with a sign that means right this way in a color that means stop?”
