“Color is a significant element in a city’s spirit. Yellow taxis add bright streaks to the corners of New York; buses and post boxes give London a spirited red kick. Pittsburgh has its proud yellow bridges and Toronto loves its blue. In his 2016 New Yorker story “Patina,” Ian Frazier writes about how once he started looking, he realized the green copper color of the Statue of Liberty is repeated all over the city: on fire escapes, facades, and roofs. “New York City’s official colors are orange, blue, and white, but its secret, sustaining color is Statue of Liberty green,” writes Frazier. “Think of all the ideas that have been in people’s heads when they looked at the Statue of Liberty. What color could stand for those ideas? What color is freedom?””
