Is Your Watercolor Light Fast

Lightfastness

The colours of many old paintings have changed over the years, that is a well-known fact. This discoloration, sometimes even complete fading, can have various causes. There are pigments that due to a reaction with substances in the air undergo a chemical change, and therefore become, for example, darker or lighter. In this newsletter, however, we refer to another cause for the change of colours, namely light. Whether a colour will change or fade in time under the influence of light, and particularly its ultraviolet range, depends on the amount of light and the stability of the pigment. This property of pigments is referred to as lightfastness.
