Gansai Tambi are Eastern Watercolors, available in 48 colors that are based off colors found in nature, and so they are vibrant without being overly saturated. Due to their richness and opaqueness, Gansai are semi-transparent and can be used as a gouache unless mixed heavily with water.

Water-based pigment paint can be highly opaque or transparent depending on the amount of water added. Wide-variety of colors makes it simple to blend colors together to make even more combinations. Replacement Gansai Tambi pans can be purchased individually. Gansai are artist-quality paints that can be used by people at any creative level.
