Formulated with the same high quality standards that distinguish their renowned paints, this professional iridescent medium is designed especially for use with Da Vinci Artist Watercolors, but works well with any watercolors.

Holbein Iridescent Medium is an artist-grade medium designed to facilitate iridescent and pearlescent effects when used with waterbased media.

This is a sparkling iridescent medium with a pearlized effect. It can be applied pure to dry paint, or mixed with watercolor to create beautiful tints. This medium has retarding qualities, slightly lengthening the drying time of colors.
