From Apple to Taxi, greenest city:) New Taxicabs are Green, Literally
The color of the city’s new taxi for boroughs outside Manhattan was unveiled Sunday by Mayor Michael R. Bloomberg, and in the mayor’s eyes the hue was an “apple green.”
“We think ‘apple green’ is attractive and distinctive,” he said at a news conference at City Hall. “It’s easy on the eyes and easy to pick out from a distance in traffic.”
