This study explores the semiotics of colours in selected poems by Nizar Qabbani, examining how color imagery functions beyond its literal meaning to construct deeper emotional and socio-political themes. Semiotics emerged as a postmodern discipline reacting against the closed nature of structuralism, opening text analysis to contextual, cultural, and extra-textual dimensions. Tracing its foundational roots from Ferdinand de Saussure’s dyadic model of semiology to Charles Sanders Peirce’s triadic framework, the field has evolved into diverse Western traditions—including the semiotics of communication, signification, and culture, as well as the Paris, Russian, and Lyon schools. Drawing upon these theoretical frameworks, this paper analyzes color signs within Qabbani’s poetry, demonstrating how color serves as a dynamic system of signification that conveys passion, tragedy, identity, and resistance.
