The U.S. Art Supply Gouache set has 36 colors in large 18 ml tubes, plus a double-sided color mixing wheel that explains color terms artists use. Gouache is an opaque water-based paint, so it covers the paper and the colors beneath it.
The paint dissolves in water for easy mixing and blending. The listing sells it as a professional set made with artist pigments, says it is water-based and acid-free, conforms to the ASTM D4236 and EN71 safety standards, and suits students through professional illustrators.
