Opaque watercolour.Also known as poster paint, designer's colour, and body colour, it differs from transparent watercolour in that the pigments are bound by liquid glue, which is used as a thinner. The addition of white pigment lightens the tone and lends opacity. Gouache paints dry to a matte finish and, if desired, without visible brush marks. They can be applied thinly or thickly. A wide range of colours are available, including fluorescent and metallic pigments. The suede finish and crisp lines characteristic of many Indian and Islamic miniature paintings is produced by this medium; it is used in Western screen and fan decoration and was used by modern artists such as Georges Rouault and Paul Klee.* * *
▪ painting techniquepainting technique in which a gum or an opaque white pigment is added to watercolours to produce opacity. In watercolour the tiny particles of pigment become enmeshed in the fibre of the paper; in gouache the colour lies on the surface of the paper, forming a continuous layer, or coating. A gouache is characterized by a directly reflecting brilliance. When applied with bristle brushes it is possible to achieve a slight but effective impasto (thick-coated) quality; with sable brushes, a smooth, flawless colour field is obtained.A painting technique of great antiquity, gouache was used by the Egyptians. It was a popular medium with Rococo artists such as François Boucher (Boucher, François) (1703–70). Contemporary painters use gouache alone or in combination with watercolour and other mediums.* * *
