For example, to create a painting that gave the impression of gold appearing in the painting, a metallic paint that glitters in an approximation of real gold would be used; a solid color does not aesthetically "read" as gold. Especially in sacral art in Christian churches, real gold (as gold leaf) was used for rendering gold in paintings, e.g. for the halo of saints. Gold can also be woven into sheets of silk to give an East Asian traditional look.
