Winsor & Newton - Water Colour Iridescent Medium

Water Colour Iridescent Medium

Add luminous shimmer to watercolors wet or dry without clouding hues

Watercolor's luminous transparency meets metallic shimmer in this dual-purpose medium. Mix it directly into wet paint to create lighter, pearlescent tones, the kind of ethereal quality perfect for moonlit water, fish scales, or fairy-tale atmospheres. The iridescent particles disperse through the pigment, creating an integrated shimmer that catches light while softening the original hue.

Applied over dry watercolor, it behaves completely differently. This top layer adds pure metallic sheen without altering your carefully mixed colors underneath. Your composition stays intact, you're simply adding light-catching dimension where you want it. This approach works beautifully for selective highlights: the edge of a wave, architectural details, jewelry in a portrait.

The effect reads as glittery sparkle rather than smooth metallic sheen, so it suits magical or decorative subjects better than strictly realistic work. Winsor & Newton formulates this medium to maintain watercolor's essential character while introducing effects traditional watercolor can't achieve. Use it subtly for sophisticated shimmer or build it up for dramatic, light-catching passages that transform under changing viewing angles.
