Pentel Arts Water Colors include a dozen rich, dramatic colors that spread and blend easily to create subtle hues. Ideal for glazing without turning "muddy", the paints dry evenly, resist fading, and will not crack or flake. Great to use in conjunction with oil pastels and color pencils. Each tube contains 5ml of acid-free water color. Tubes allow every last drop of paint to be used. Once colors are dry on palette, they can be re-used by applying water. Colors included: White, Prussian Blue, Yellow, Red, Lemon Yellow, Vermilion, Yellow Green, Brown, Viridian, Yellow Ochre, Cobalt Blue, Black.
