In literature, "espresso" is sometimes invoked as a color descriptor that evokes the rich, dark hue of a perfectly brewed coffee—suggesting warmth and subtle depth. For instance, in example [1] the term "Cafe Espresso" is paired with Italian bread, immediately conjuring an image of a robust, dark tone that parallels the beverage's enticing quality. This use of "espresso" as a color not only adds a sensory layer to the description but also imbues the scene with an atmosphere of both rustic charm and refined taste.
