There are currently nine taxi colors in Shanghai (is “Expo” a color?) and the city is now promising to gradually consolidate the hues to one main industry color, according to the Shanghai Port Authority. Under instructions from the CPPCC, Shanghai’s five major taxi companies will eventually switch to a uniform color to promote the “overall image of the taxi industry in Shanghai.” They are also considering ways to make passes for the various companies universal, to save you the hassle of waiting around for the correct company’s cab. Anyway, what do you say Shanghai? Which color should our cabs be? Sandstorm sepia? Communist Cadre Crimson? Propaganda Periwinkle? Expo Emerald? Swill Oil Saffron? Xiaojie Cerulean?
