Conservation
of Pigments...
Some paintings have to be kept in semi-darkness to stop the pigment in
the paint from fading any further. Whether colours fade or not depends
on where they come from. Some pigments are more sensitive to sunlight
than others.
The
faces of the people in the painting above appear very pale. The pink glaze
which the artist used to tint the skin has faded due to exposure to ultra-violet
light.
