Schmincke Horadam Gouache is aimed at the professional artists and cannot be considered just an opaque watercolour- a widely held perception with many gouache ranges. Horadam Gouache is the finest grade gouache made with artists' grade colours with the best genuine artists' pigments. Highly concentrated for brilliance and depth of colour. Velvet-matt and opaque finish. One of the distinguishing characteristics of Horadam Gouache is unlike all other brands no white is added to artificially boost covering power. This enables serious artists to create crisp colour blends like no other gouache. Of the 48 colours, all but 8 are based on a single pigment. Lightfast levels equate with professional quality artists paints. Like Horadam Watercolours, these gouache colours thin with water and are easily rewetted if left to dry on the palette. Horadam Gouache is so finely ground; it can even be used for 0.15 mm airbrush work. Many other brands of gouache are "designer" gouaches, with an emphasis on accurate pre-mixed colours for use by the designer. By contrast, Horadam is a "fine artist" gouache, with an emphasis on providing the classic range of pigments as pure, single-pigment colours.
