"Ezumi" Ink-Based Colors by Boku-undo Since its release in 2001, "Ezumi Colors" have been highly popular across a wide range of generations. Its charm lies in its ability to express a profound monochrome world. These versatile colors are ideal for Japanese paintings, ink paintings, calligraphy, illustrations, and more. Developed based on Boku-undo's ink technology since 1805, these colors have been created through thorough research and experimentation in terms of hue, brightness, saturation, and expressive power. Using a water brush, you can easily apply color to watercolor paper or ink paper. Like solid ink, Ezumi can be stored for a long time and offers high expressive power for shadows, gradients, and blurring. From beginners to professionals, everyone can enjoy the changes and separations of colors.
