In literature, ultraviolet is not solely a technical term for a portion of the electromagnetic spectrum but also an evocative color that defies conventional perception. Writers have used ultraviolet imagery to suggest a mysterious, almost otherworldly hue that exists at the edge of human vision. For example, one text contrasts the “violet or ultraviolet end” of the spectrum with more familiar colors like red to evoke subtle emotional and symbolic divergence [1]. In another instance, the image of an “ultraviolet beam piercing the starlit darkness” transforms a scientific phenomenon into a poetic metaphor, lending its eerie radiance a quality both tangible and ineffable [2]. Such usages illustrate how ultraviolet, as a color, opens up imaginative spaces where light and shadow intermingle in unconventional ways.
