Patrick Zachmann is a master of teasing out color in the subterranean and the after-dark. Daytime doesn’t have the monopoly on color, after all; it’s there at night, too, albeit altered by its battle with darkness and uneasy relationship with artificial light. “Ugly and grey during the day, a city becomes attractive at night, or sometimes frightening,” Zachmann says. “The lights change, hot or cold, colliding prettily into a mix of color temperatures. They make faces smooth, mix up ages, blur signs of belonging and allow silhouettes lit by a street lamp or a car headlight to be discovered.”
