Use Gansai Tambi watercolors to create artwork with beautiful, luminescent colors. The pigment is both dense and homogenized; each stroke of color goes a long way, offering smooth, even color. Each watercolor pan in this set reflects various color tones depending on the angle from which they are viewed. They shine in pale, pearly tones on white paper, and exhibit a strong, metallic sheen on dark-colored paper. The stronger and more direct the light, the more they sparkle and shine. This set contains pans of opal pink, opal copper, opal gold, opal green, opal blue and opal violet.
