Holbein Acryla Gouache Burnt Umber 20 ml

D133 D833 Burnt Umber/Terre d’Ombre Brûlée - PBr7 Mars Brown (Iron oxide)

Holbein Acryla Gouache is an opaque and highly pigmented paint that dries to a velvety-matte finish. In terms of handling and mixing, it behaves like traditional Gum Arabic gouache, but because it is made with an acrylic resin binder, it is water-resistant once dry, facilitating layering, as fresh paint layers can be laid down without the risk of bleed-through from the lower layer. Acryla Gouache dries quickly and with minimal colour-shift; what you see wet is what you get once the paint has dried.
