Winsor & Newton Iridescent Medium
Winsor & Newton Iridescent Medium
This specialty medium adds a pearlescent or glitter effect to watercolours, and can be mixed directly with watercolours, or applied over a dried wash. The iridescent effect works well when applied over darker colours or on darker paper. Try experimenting with different shades of paper for your own unique techniques and effects.
