Lightfastness is a property of a colourant such as dye or pigment that describes its resistance to fading when exposed to light. [1] [2] [3] Dyes and pigments are used for example for dyeing of fabrics, plastics or other materials and manufacturing paints or printing inks.
In natural dyeing, there are "fast" dye compounds (those that have the necessary molecular structure to form stable chemical bonds with mordants and fibres, and so provide good resistance to fading when washed, exposed to light, or subjected to normal rubbing/abrasion; these are found throughout the historic record), and there are "fugitive ...

Dye is generally applied in an aqueous solution and may require a mordant to improve the fastness of the dye on the fiber. [2]
