The Chinese word **夜色** (yèsè) is a compound noun formed by combining the character **夜** (yè), meaning "night," with the character **色** (sè), which in this context means "color," "hue," or "atmosphere." It follows a common modifier-head structure in Chinese, where the first element (**夜**) describes and specifies the second (**色**). Literally, it translates to "the color of night," but it functions as a single lexical unit meaning "nighttime scenery" or "the visual ambiance and dim light characteristic of the evening." This formation creates a poetic, evocative term that encapsulates both the literal darkness and the aesthetic mood of the night.
