Colorfastness

Colorfastness refers to a material's ability to retain its color when exposed to various elements like washing, sunlight, or sweat. In textiles, for example, a colorfast fabric won't fade or bleed during normal use or cleaning. This quality is important because it affects the appearance and longevity of clothing and other items, ensuring they look good for longer. Tests are conducted to measure colorfastness, and materials with high colorfastness are generally preferred in fashion and design, as they require less maintenance and remain vibrant over time.
