In some literary passages, authors use "cobblestone" not just to denote a building material but as an evocative color that suggests muted, weathered hues reminiscent of aged city streets. For example, one work describes a “yellow cobblestone,” where the adjective “yellow” imbues the stone with a sun-bleached, almost nostalgic quality that hints at both urban decay and lasting resilience [1]. In another instance, an object is noted as being “gray” in a way that makes it resemble a cobblestone, thereby evoking the cool, natural tone of stones worn by time and weather [2]. These uses illustrate how the color “cobblestone” can conjure visual textures and atmospheres that enrich the setting with both historical and mood-specific connotations.
