In literature, “sea blue” has been employed as more than a mere description—it is a dynamic color that bridges the natural world and human emotion. Writers evoke expansive, shifting seascapes by describing distant skies and waters in hues like “deep-sea blue” that suggest both mystery and majesty [1, 2, 3, 4], while other passages use variations to capture ephemeral moments or transformative moods—as when the “mighty tide of khaki gold merged with the deep sea blue of heroes” [5] or when a room is “painted a delicate sea blue” [6]. The color also finds intimate application in character portrayal, lending softness and depth to features like “Red’s sea blue eyes” [7, 8]. Throughout these examples, “sea blue” emerges as a versatile literary tool, its mutable tone representing not only the physical beauty of nature—from sunlit coasts and cloudy day vistas [9, 10, 11, 12] to the shimmering allure of cascading hues [13, 14]—but also the inner, often ineffable, contours of the human spirit.
