In literary settings the word “dolphin” has been occasionally repurposed as a color descriptor, diverging from its usual reference to the marine animal. One notable example comes from a poetic line that speaks of a “dying day with dolphin-hues,” where the term is used to evoke a particular, subtly shifting spectrum of muted blues and grays that imbue the scene with a somber, reflective quality [1]. This instance illustrates how authors can creatively borrow the evocative, fluid nature of the dolphin image to suggest an atmospheric tint, transforming a simple animal name into a metaphor for natural, transient light and emotion.
