TONIC WATERCOLOR — MODERN MIXING TUBE SET This handsome kraft-and-silver box contains the five most versatile colors of our Tonic Watercolor, all in 12 mL tubes. They're easy to mix into full-spectrum color, and with the included opaque white and black, you can experiment with a full range of values and opacities, too. Perfect for color theory and design classes, because even beginners can mix bright and intense colors across the spectrum. The simplified palette encourages you to practice all kinds of color mixtures, including three-color earth-tone blends (this set makes some lovely neutrals, even though our primary colors are very bright.) Not limited to any particular style or subject, the Tonic Modern Mixing Set is a great standalone choice for any watercolor or gouache artist.
