Talens Extra Fine Gouache is a highly pigmented poster paint with a matte finish. This poster paint is popular among artists and designers for its intense and opaque colors. It can be made slightly more transparent by adding water. The poster paint is made with a high concentration of high-quality pigments and is based on dextrin, which gives the paint a smooth consistency and reduces surface gloss. Use the poster paint to create even, matte color blocks without visible brush strokes. Mix the colors with water to dilute, blend, and create soft color gradients. The poster paint is not water-resistant after drying, meaning you can still work over the colors with water after they have dried.
