The wonderful six tube set of Alvin watercolors (15 ml each tube) is perfect for both students and professionals alike. Colors are bright. Colors are clear and saturated. The paint has a honey-like texture when it comes out of the tube, a consistent smoothness, and dissolves readily in water. The colors mix easily. It resists running when re-wetted because the paint stays in place once the paint has dried. The intense hues have greater vibrancy and all are fade resistant which means your masterpiece will last longer. The Alvin watercolor paints have strong light-fastness ratings. This kit is a great value, of all the primary colors, for a modest price.
