Add luminous, color-shifting effects to your artwork with the Kuretake Gansai Tambi Opal Colors Set. This collection includes six shimmering watercolors with an iridescent, opalescent finish that changes beautifully depending on the viewing angle and light. Especially striking on dark or colored paper, these paints are perfect for adding glowing highlights, decorative details, lettering, illustration, and mixed-media accents. Like traditional Gansai Tambi colors, they activate easily with water and offer smooth, rich application. The set includes six individual pans in a convenient palette, making it an eye-catching addition to any watercolor or sketching kit.
