This article examines the strategic use of colour symbolism in Alice Walker's Pulitzer Prize-winning novel The Colour Purple (1982). Through close textual analysis, this research demonstrates how Walker employs a sophisticated colour palette to underscore the novel's central themes of transformation, resilience, and spiritual awakening. The article pays particular attention to purple, white, red, and green as symbolic chromatic elements that reflect the protagonist Celie's journey from oppression to empowerment. By tracing the evolution of these colour symbols throughout the narrative, this study reveals how Walker's chromatic choices function as a visual lexicon that both enriches character development and reinforces the novel's exploration of race, gender, sexuality, and spirituality in early twentieth-century rural Georgia.
