Gouache
Opaque water-based paint (also known as body colour). Like watercolour, it is made from powdered pigment mixed with gum Arabic but with the addition of glue to bind the pigments. In use it differs from watercolour in that white pigment is added to make lighter tones rather than by simply adding water. It has been much used by illuminators and painters of miniatures.
