Description

The gradual loss of brightness or color. Fading is an irreversible process due to chemical alteration, such as oxidation, of the color-forming compound. Non-lightfast, or fugitive, pigments and dyes can loose color with exposure to ultraviolet light in the presence of oxygen and moisture. Comparative studies of fading for various materials can be done with a fadeometer.
