雪白 (xuě bái) is a compound adjective meaning 'snow-white' or 'pure, brilliant white'—evoking the pristine, luminous whiteness of freshly fallen snow. The first character 雪 (xuě) means 'snow', and the second 白 (bái) means 'white'; together, they form an intensifying descriptive phrase that emphasizes both purity and brightness, not just color. Unlike the simple adjective 白, 雪白 carries poetic and vivid connotations, often used for things that are exceptionally clean, unblemished, or naturally radiant.

This term frequently appears in literary descriptions, nature writing, and everyday speech when emphasizing visual purity—such as describing the fur of certain animals (e.g., polar bears or white rabbits), fresh cotton, bridal gowns, or winter landscapes. It’s commonly used attributively before nouns (e.g., 雪白的羽毛) and can also function predicatively (e.g., 它的毛色雪白). While not formal or technical, it’s widely understood across all registers and ages.
