The color "gunmetal" is often used in literature to evoke a sleek, industrial, and sometimes foreboding atmosphere. In some passages, gunmetal is not merely a neutral shade but becomes a metaphor for modernity and mystery. For example, Broadway is described as "black and shining as polished gunmetal," blending urban grit with a reflective, almost cinematic quality [1]. Meanwhile, the sea is characterized as gunmetal under the stars, an image that lends a sense of vast, dark, and shifting depths amid nature [2]. In other texts, gunmetal is used to accentuate both the elegance and the stark functionality of objects—a watch with a gunmetal finish [3, 4, 5] or even the contrasting tones aboard a ship, where the cool sheen of gunmetal-and-chrome stands apart from softer hues [6]. Additionally, poetic imagery such as swamps glittering like rusted gunmetal [7] highlights the color’s association with decay and resilience simultaneously, revealing a layered symbolism that enriches the narrative landscape.
