In Willemstad, the capital city on the island of Curaçao, the waterfront is dotted with buildings the color of tropical fruit: mango orange, banana yellow, kiwi green. Paired with the bright blue water in nearby bays, it’s almost a full kaleidoscope of color. Originally, the structures were limestone white, but an 1817 law forbade white facades on buildings to protect islanders’ eyesight from the bright reflections of the Caribbean sun – but locals joke that it was a money-making bid on behalf of the island’s only paint supplier.
