Winsor & Newton's Artists Acrylics are unrivaled in their brilliance and depth of color bringing exceptional richness and intensity to your paintings. The brilliance of Artists Acrylics can be seen in the clarity and purity of their color which is evident when the color is applied straight from the tube as well as in the thinnest of films. The working time with Artists Acrylic is approximately 20% longer than other acrylic paints- giving you more time to work before the acrylics dry. Once dry, the colors all have a uniform satin finish.
