Writers have long employed dusk not just as a marker of time but as a distinct, evocative color that imbues settings and characters with a transient, atmospheric quality. In some texts, dusk is fused with another hue to paint a visual mood; for example, the “blue dusk” in [1] and in the description of a woman’s hair in [2] creates a serene yet wistful appearance. Authors also use dusk as a subtle pigment when describing physical features, as seen in [3], where a character’s visage is rendered with a mysterious, shadowy hue. Meanwhile, an interior space is suffused with a “coloured dusk” in [4], lending an otherworldly, softened quality to the scene, and nature itself can be portrayed as embodying this twilight tone—as when the woods are set against the backdrop of dusk in [5] or even transformed into a “green dusk” in [6]. In these examples, dusk transcends its literal meaning to function as a color that conveys mood, mystery, and sensory depth.
