One of the major themes in "The Great Gatsby" is dissatisfaction. One character in particular, Jay Gatsby, is not satisfied with his life. Even though he is very wealthy and owns an extravagant home, he always wants more. He finds himself frequently following and obsessing over Daisy. In the end, this obsession is what ultimately ruins him. He becomes so caught up in something that he cannot have, and therefore he is always dissatisfied. The word on this poster is painted in green because green symbolizes desire and hope in the book. Gatsby desires Daisy and therefore it is appropriate to paint this theme in green.
