Turner Poster Color is an opaque watercolor paint that you mix with water. The pigments are bound with gum arabic and other natural binders that dissolve in water. Large areas go on with few brush marks, and the finish is matte.
It comes in 40 ml bottles and an 11 ml size, and each color is sold individually. Sets include 8, 12, 13 and 18 colors in the 11 ml size, and 12 and 18 colors in the 40 ml size.
White or light colors painted over a dry dark color do not bleed into it. This lets you add bright patterns or highlights afterward.
