Artists’ Iridescent Watercolor

Holbein’s transparent watercolors are now available in the vivid and playful “Luminous Color (fluorescent color). This lineup includes fluorescent colors, which are rare among watercolors, and fluorescent blue, which is even rarer among fluorescent colors. The addition of 12 Luminous Colors with high brightness and saturation further expands the range of expression in watercolor. 

***Holbein Japan Update May 2026 (Notes on use for Luminous Watercolors in 5ml and 15ml tubes): Please take note that some Luminous Watercolors emit a noticeable odor. This is a normal characteristic of the materials used and doesn’t affect the paint’s quality or performance. 

We also recommend squeezing out only the amount of Luminous watercolor paint needed for immediate use and keeping the remaining paint sealed in the tube. Luminous Watercolors do not rewet easily.
