Winsor & Newton Watercolour Iridescent Medium

Winsor & Newton Iridescent Medium is a professional acrylic medium designed to create shimmering, pearlescent effects and luminous colour highlights in acrylic painting. Formulated with fine mica particles, this medium adds a subtle iridescent sheen that catches and reflects light, producing dynamic surface effects and enhanced visual depth.

Ideal for mixed media, decorative painting, glazing, and contemporary acrylic techniques, Iridescent Medium can be mixed directly with acrylic colours or applied as a translucent top layer to create metallic and pearlescent finishes. The medium enhances luminosity without significantly affecting paint consistency, allowing artists to achieve soft shimmer effects or more dramatic reflective finishes depending on application.

Suitable for use on its own or blended with acrylic paints, Winsor & Newton Iridescent Medium maintains flexibility and durability while producing a smooth, satin-like finish with light-reflective qualities. It is especially effective for highlighting textures, creating atmospheric effects, and adding dimension to abstract, illustrative, and decorative artwork.

Suitable for professional artists, designers, and mixed media creators, Winsor & Newton Iridescent Medium is ideal for adding brilliance, shimmer, and contemporary surface effects to acrylic painting applications.
