60 Quick-Drying, Highly-Pigmented Gouache Shades Long beloved by professional illustrators, gouache pigment allows for vibrant colors. The white of the paper does not show through, unlike transparent watercolor, and this makes the application of the paint a different experience from traditional watercolor. Our gouache tube set is great for layering, glazing, texturing, detailing, and blending. What We Love About Our Arteza Gouache Paint Set: Vibrant and opaque colors, packed with pigment.
