Gouache (fr. gouache — "wet") is a type of painting to use matte water-soluble paints. These paints are also called gouache. Gouache appeared in the 11th century, when glue and whitewash were added to watercolours to achieve greater density. Its consistency creates an opaque image, it can overlap the "bad" places. In the Middle Ages, book miniatures were created with gouache paints. Renaissance
artists used them for sketches. In Russia, gouache has become popular among poster
artists. In easel painting, it is used to design decorative elements, together with ink or watercolours. Gouache works well not only on paper, but also on canvas, plywood, fabric. The paint is first applied in a thin layer, and then overlaid more densely. There is art and poster
gouache. The latter is characterized by high saturation.
