Daniel Smith Extra Fine Watercolor Sticks offer the same superior intensity as the Daniel Smith line of Extra Fine Watercolor paints with the convenience and portability of half pans. Each stick is packed with pure pigment and produces vibrant strong color when wet or use them dry to build texture. They’re highly reactive with water and release rich creamy colors. New Gamboge is an excellent lightfast formulation. It's a transparent organic pigment from the yellow to orange zone of your color wheel. More staining than Yellow Ochre and equal in tinting ability to Raw Sienna. It's a good substitute for those colors when transparency is desired while avoiding thick muddy passages.
