Lightfastness

Lightfastness is a property of a pigment or paint that describes how resistant to fading it is when exposed to light.

Description

Light striking a painted surface can alter or break the chemical bonds of the pigment, causing the colors to bleach or change, in a process known as photodegradation.

Materials that resist this effect are said to be lightfast.
