Fugitive pigments

From Wikipedia, the free encyclopedia

Fugitive pigments, are non-permanent pigments - pigments that lighten in what is understood, said or defined to be a relatively short time when exposed to light. Fugitive pigments are present in types of paint, markers, inks etc., which are used for temporary applications.

While paintings are often done with permanent pigments, painters have made work wholly or partially with fugitive pigments for a number of reasons: ignorance as to the permanence of the pigments, prioritising the appearance of the colors one can get with fugitive pigments over permanence, or the desire to have a painting change in appearance over time.
