Explore the luminous possibilities of Williamsburg Oil Colours Iridescent Colours, a unique range of shimmering oil paints designed to capture and reflect light with striking brilliance. Crafted using finely ground mica, these colours offer exceptional colourfastness and permanence, ensuring metallic and nacreous effects that will never tarnish over time.

Each pigment is milled into microscopic, prism-like particles that refract light to create a radiant, opalescent glow. This gives the range its signature semi-translucent quality, allowing light to pass through the paint film and produce dazzling interference effects—similar to the shifting colours seen in a fire opal. From subtle interference violets to glowing metallic tones, these paints come alive when layered as glazes, revealing vibrant flashes of colour as they catch the light.

Perfect for adding depth, dimension, and a contemporary edge to your work, Williamsburg Iridescent Colours are best used with a light touch—preserving their brilliance and optical effects for truly captivating results.
