I was in Mexico on vacation, so thankfully it didn't take much work to figure out what the colors of Puerto Vallarta were. They were, after all, the featured colors on the Jalisco state license plate. Beyond that, the colors blue and white, frequently paired with a splash of yellow, flowed throughout the city. The hues gleamed in glossy painted tiles, shone on colonial balconies, and brightened up neighborhood liqour stores. And, more obviously, they were the colors of the city's star attraction, the beach, where they appeared in the blue waves, white sand, and glints of yellow sun.
