The color yellow most often represents wealth that is flashy, corrupt, or destructive.
Yellow is closely tied to money, but not the stable, inherited wealth associated with “old money.” Instead, it signals something more artificial—wealth that is showy, excessive, and often tainted. Gatsby’s “new money” world is filled with this kind of color: his parties feature food and decorations described in rich golden tones. In Gatsby’s mansion, everything looks luxurious but feels hollow underneath, which the novel suggests is true of 1920s American culture more generally.
The most important yellow object in the novel is Gatsby’s Rolls-Royce, which becomes the instrument of Myrtle Wilson’s death. The symbolism is clear: the same glittering wealth that defines Gatsby’s rise also brings about tragedy. The car is actually mistaken for “light green,” which subtly relates it to the green light at the end of Daisy Buchanan’s dock. In this way, the Rolls-Royce and the color yellow are linked to Gatsby’s dreams of wealth and love—dreams that ultimately bring about Gatsby’s downfall.
Yellow also appears in the “enormous yellow spectacles” on the billboard of Doctor T. J. Eckleburg. Those glasses loom over the Valley of Ashes, a place defined by decay and poverty. The pairing is striking: a color associated with wealth sits above a landscape of ruin, suggesting that the upper class overlooks—and perhaps causes—the moral and social emptiness below.
The color yellow is, in a sense, gold that has lost its purity or richness. It therefore symbolizes the Jazz Age’s obsession with wealth that dazzles at first glance but leads to carelessness, moral decay, and, in the end, death. This symbolism emphasizes the fact that the more intensely characters chase materialism and luxury, the more destructive they become.
