Colorfastness encompasses both wet and dry crocking and fastness to light.

Colorfastness refers to a material's ability to maintain its color when exposed to various conditions, including washing, rubbing, light exposure, and environmental factors. The concept indeed includes both "wet and dry crocking," which relates to the transfer of color from a fabric to another surface when subjected to friction, whether it's wet (with moisture) or dry. Additionally, "fastness to light" addresses how well a color resists fading or change when exposed to sunlight or artificial lighting over time.

Understanding colorfastness is crucial in textile selection for interiors, as it affects the longevity and appearance of fabrics in different environments. Therefore, the assertion that colorfastness includes both wet and dry crocking as well as fastness to light is accurate, affirming that the materials will not only endure physical abrasion but also retain their vibrant quality in lighting conditions.
