35 colors, 15 ml tubes. Hand-crafted in the USA with pure honey, gum arabic and the most beautiful pigments available. These colors provide brilliant, and particularly smooth, even performance. Most watercolors contain sugar; using honey provides a smoother paint. Classes and attenders at Discoveries found these paints to be brilliant and semi-opaque, about midway what you'd expect from a watercolor and a gouache. Their positive responses, the large 15 ml tube size and these 40% off introductory prices make these a great new item to try. Excellent pen flow, luminous washes. Lightfastness ratings for all but three colors are excellent; Dioxazine Purple and Naphthol Red are very good; Alizarin Crimson is fair.
