This Primary Mixing set includes one each of three primary colors (Hansa yellow medium, pyrrol red and ultramarine blue) for mixing secondary colors, and titanium white for adjusting the shades. Daniel Smith Gouache is a professional artist-grade gouache that produces an opaque matte finish. Made with the same high-quality pigments and gum arabic as Daniel Smith Extra Fine Watercolors, it is formulated with higher pigment loads to achieve density and opacity without adding whites or other fillers. It can be applied as mass tone straight from the tube to get rich, full-bodied solids with single brush strokes. Colors can be smoothly tempered with water to create softer lines and hazy layers. This set includes four 15ml tubes.
