Lightfastness is the degree to which a dye resists fading due to light exposure. Different dyes have different degrees of resistance to fading by light. - http://www.pburch.net/dyeing/FAQ/lightfastness.shtml

Lightfastness Rating - What It Means
The lightfastness or permanence of a pigment is its resistance to change on exposure to light. This depends on the chemical nature of the pigment, its concentration, and the medium in which it is employed — oil, watercolour, acrylic. - http://goo.gl/NWERl
