iroe2 APP

"Iroe" is a design tool featuring color samples of the pigments used in Saga Prefecture's porcelain. Using these colors and patterns, you can paint pottery in accordance with the manufacturing process. "Iroe" was developed as part of the "Ceramic Color Pallet" app development contract with the Saga Ceramics Research Center and released in April 2023. This app is the second in the series.

"Iroe" allows you to easily view color samples of actual underglaze and overglaze pigments, select the shape of the vessel, use line and smear brushes, and design using pattern stamps, allowing you to experience the craftsmanship of the region on your smartphone. The pattern stamps use patterns from the collection of the Kyushu Ceramic Museum, Saga Prefecture, allowing you to enjoy the pattern designs of our ancestors.

In addition, completed designs can be saved as an archive and enjoyed as your own original pottery designs. People of all ages can easily experience the charm of traditional crafts digitally.

With "iroe 2," donors can now create designs freely on the app as a return gift for Saga Prefecture's hometown tax donation program. Each piece is hand-painted by a skilled traditional Imari or Arita porcelain artisan, creating a one-of-a-kind piece.

This is the first time in Japan that users can design designs on the app, have them recreated by a traditional artisan, and offer them as a product. The goal is to allow people to experience the charm of porcelain's colors and culture up close. It was created with the hope that people of all ages, from children to adults, will enjoy painting and discover the fascinating color combinations that make them appreciate the art.
