Final answer:
Nick Carraway is the narrator of 'The Great Gatsby,' offering a personal and limited perspective on the story and its themes.
Step-by-step explanation:
The narrator of The Great Gatsby is B. Nick Carraway. He gives readers a view into the life and times of the title character, Jay Gatsby, as well as the social environment of 1920s East Egg, New York. Fitzgerald’s use of a single, flawed narrator allows for a personal yet limited perspective, enabling the novel to highlight themes such as hope, decay, and the illusion of purity during the post-World War I era. Nick's interactions and observations, including the descriptions of colors and the interpretation of their symbolism, contribute crucially to the novel's thematic complexity and intimate tone.
