One notable literary use of “concrete” as a color appears in the observation that “Poetry differs from prose in the concrete colors of its diction” [1]. Here the term transcends its physical association with building material to evoke a rich, tangible quality in language—suggesting that poetry, unlike prose, is marked by vivid, specific hues that give its words a palpable texture. This metaphorical employment of “concrete” transforms an otherwise mundane shade into a symbol of clarity and substance, grounding abstract concepts in a perceptible reality that resonates with the reader’s sensory experience.
