Gouache, as watercolour, is water-soluble colour based on gum arabic. However, as opposed to transparency and aeriality of watercolours, one of the most valuable properties of gouache is high opacity – the ability of colour to overcoat underlying layer.

‘Master-Class’ gouache is distinguished by perfect covering ability and paint layer density. Paint layer becomes matt velvety after drying. All these properties allow using it in serious art and graphic works.
