The term "discolor" has served multiple purposes across literary works, demonstrating both metaphorical and literal applications. In one instance, it appears as a metaphor for moral or existential taint—Yogananda questions whether superstition might "discolor the powerful waters" or his pursuits, suggesting an unwanted corruption of purity [1]. Conversely, Whitman uses "discolor" in a tangible, descriptive sense, painting a vivid picture of a cityscape marked by industrial grime, where wooden houses are visibly altered by the elements of urban decay [2]. Additionally, the term is employed in a taxonomic context in James Mooney’s work, where it forms part of the scientific epithet for a water beetle, signifying a notable characteristic of its appearance [3].
