Scott Fitzgerald used colors in The Great Gatsby to portray more than just images. Fitzgerald used colors to convey emotion, setting and underlying tones for patterns. The character Daisy can be interpreted as a metaphor. You can connect the colors used to describe Daisy in the book to interpret her motivations and emotions through the dichotomy of a daisy flower. One way to interpret Daisy is that the green of the stem describes the structure of her character, the white of the flower describes what others see of her, and the yellow inner part of the flower describes what is truly inside her.
