Intensity and long exposure times can lead to fading or changing colors in dyes and colorants. Light and ultraviolet radiation (UV) provides energy to fuel the chemical reactions that lead to deterioration and while UV is blamed for most of this damage, visible light is also problematic. Aside from fading, there may be damage to the physical and chemical structure of materials. Many materials are particularly sensitive to light: paper, cloth, leather, photographs, and media (inks, colorants, dyes, and many other materials used to create objects and art). Light is a very common cause of damage to collections.
When we think of light damage, we think of fading, but fading is only the most recognizable form of damage.
