Well, the grass is purple, and the trees are purple, and the houses and fences are purple. Even the mud in the roads is purple. But in the Emerald City everything is green that is purple here. And in the Country of the Munchkins, over at the East, everything is blue; and in the South country of the Quadlings, everything is red; and in the West country of the Winkies, where the Tin Woodsman rules, everything is yellow.
