The strongest theme pervading The Great Gatsby is that American idealism has been corrupted by adopting materialism as its means. Various symbols and images throughout the novel support this idea. .
The corruptive effect of wealth is shown by the conflict between the established rich and the newly rich, represented by the people in West Egg versus the people of East Egg. .
The people of East Egg see themselves as the elite setting trends and that the people of West Egg are imitating them, the East Eggers see the people of West Egg as lower than they in the social hierarchy. However, when viewed from a distance they appear the same "a pair of enormous eggs, identical in contour-. This proves: how superficial their society is.
As Nick points out in the novel, "Tom and Gatsby, Daisy and Jordan and I, were all Westerners,"" in moving to the east they move from a world of stable values into a "new- world created by the rich and upper class that contains a moral vacuum represented by the .
"valley of ashes- .
Colour plays a major role in the novel "the moon had risen higher, and floating in the sound was a triangle of silver scales- The silver moonlight described in this extract from the text exemplifies F. Scott Fitzgerlad's use of images and colour. Silver and gold, the colours of wealth are seen again and again, "Gatsby, in a white flannel suit, silver shirt and gold coloured tie-. Daisy's colour is white; she wears a white dress and recalls her "white girlhood,"" and this use of colour helps to portray her as the unattainable pure princess who exists in Gatsby's dreams and is unreachable. .
Two important symbols in the novel are the green light at the end of Daisy's dock and the eyes of Doctor T. J. Eckleburg. The first is a perfect example of the way in which characters in The Great Gatsby infuse symbols with meaning "the green light is only a green light, but to Gatsby it becomes the embodiment of his dream for the future, and it beckons to him in the night like a vision of the fulfilment of his desires.
