What Causes Fading?
To understand the causes of fading, one needs to know a little about the makeup of sunlight.
Sunlight is basically made up of three elements:
- Visible light – the part which enables us to see
- Infrared light – the part which we feel as heat
- Ultraviolet light – we cannot feel it or see it, but it is the main factor in causing fabrics, furniture, and works of art to fade
