Holbein Acryla Gouache moves, reacts, blends and feels like traditional gum-arabic gouache and is water resistance once dry. Dries to a velvet matte finish; Holbein Acryla Gouache does not shift in color tone from liquid to dry color. This unique paint does not have the same fragile surface as traditional gouache in gum-arabic and is compatible with all other water soluble media regardless of origin
