Description
The ability of a color to maintain its tone and hue when exposed to daylight. Ultraviolet radiation in sunlight can irreversibly break chemical bonds, thus altering the composition, and thus color absorption capabilities, of many organic colorants. Lightfastness is used to describe colors used in artists paints, industrial paints, printing inks and textile dyes. Lightfastness tests can be conducted with either direct exposure to sunlight or simulated exposure in an indoor chamber with an artificial light source. The lightfastness of a color can be affected by the quantity and type of binding medium.
