In “The Great Gatsby”, F.Scott Fitzgerald brings his readers a vivid illustration of the deterioration of the American Dream and moral decay in the “Roaring twenties”. Fitzgerald uses extensive colour symbol for characterization development, events connection and thematic manifestation. Specifically, Fitzgerald expresses an incisive social analysis of the corruption in the 1920’s America by bestowing deep meanings in the choice of three colours, green, white and yellow. These three colours emphasize how one’s blind pursuit of dreams, conception of materialism and ruthless manipulation of money is deemed dangerous and destructive. Colour green is introduced at the onset of the novel to represent Gatsby’s hope and dream to win back Daisy with his wealth. This colour is embedded in the metaphor of the green light that Gatsby sees at the end of Daisy’s dock. Nick recalls his first impression of Gatsby stretching out his arms towards “a single green light, minute and far away, that might have been the end of a dock” (Fitzgerald 21). Gatsby sees Daisy to be the sole motivation and meaning in life, describing her to “always have been a green light that burns all night at the end of the dock” (Fitzgerald 92). This man-made light that shines in “the unquiet darkness” (Fitzgerald 21), symbolizes Gatsby’s unfailing hope and confidence in getting Daisy with his acclaimed wealth, represented by the green American dollar bills. He lives and dies for this dream, as Nick remarks, “Gatsby believed in the green light” (Fitzgerald 180). In the end, Gatsby’s flame of hope in his mind’s construction invested over wiping the past and gaining Daisy extinguishes in the darkness of reality. In the novel, Fitzgerald manipulates white colour to convey his message how aspiration of material wants can be hidden behind the facade of innocence. Daisy first appears in the novel with Jordan Baker “in white, and their dresses were rippling and fluttering” that suggests that their innocence and purity. Notably, Fitzgerald also reinforces the elements of innocence in his description of Daisy’s house: “the windows were ajar and gleaming white” (Fitzgerald 8). Although Daisy may look innocent, she is extremely materialistic and she is willing to marry a man for money. Gatsby knows her well and tells Nick his understanding of Daisy, “Her voice is full of money” (Fitzgerald 120). Her name, Daisy, a white flower with yellow center, exhibits her true nature. While she may look innocent, “high in a white palace the king’s daughter” (Fitzgerald 120), she is “the golden girl” (Fitzgerald 120), one who uses her appearance to manipulate the world for material gains. Far from being the desirable dream girl, Daisy is poor in moral.On the other hand, Fitzgerald uses the colour yellow to exemplify the evil of money as a commodity. Anxious to show off his wealth as a way to attract Daisy, Gatsby wears a gold tie and drives a yellow Rolls Royce. The luxurious car spins around town, picking up guests to attend his weekly party, powerfully symbolizes wealth and crass materialism that corrupts the American society. Nick describes the car to have “a rich cream colour, bright with nickel, swollen here and there in its monstrous length” (Fitzgerald 64). This description reminds readers that acquiring wealth immorally is a sickness and is dangerous. Myrtle is killed in the end of the novel as she flees from Wilson’s captive. Mistaken the yellow car to be Tom’s, Myrtle runs towards it, “waving her hands and shouting” (Fitzgerald 137). Fitzgerald portrays Myrtle’s death scene to magnify the idea that immoral pursuit of money kills, a concept later expanded in the murder of Gatsby. Before he was shot by George Wilson, the colour of autumn leaves depicted that he refused the chauffeur’s help and “disappeared among the yellowing trees” (Fitzgerald 161) which predestined his death. Fitzgerald uses yellow to decouple the ideas of wealth and greatness, instead, he associates richness with corruption and amorality which ultimately brings to death.With effective use of colour symbolism, Fitzgerald powerfully demonstrates the use of the destruction of hope with obsessive pursuit of the American Dream, the concept of materialism and the disastrous consequence of acquiring material wealth immorally. Green, white and yellow therefore evidently reveal Gatsby’s condemn of dishonesty and absence of moral behind innocence looks, wastefulness in an excessive material life and the disillusion and distortion of one’s ideals.
