What is interference paint?

Sometimes called pearlescent or iridescent pigments, interference pigments are a polymer emulsion (paint) containing titanium-coated mica flakes. Because they interfere with light waves, technically interference paint is the most accurate term. Painted over a dark color, you see the labeled interference color. Painted over a light color, you see the complimentary color. The color changes depending upon the angle you've viewing the paint at.

While this type of paint was previously only seen in acrylic varieties, there are now oil crayons that feature interference pigments. The paints are not intended for use alone, and work best in conjunction with other paints. Click through to see professional advice on how to use interference paint.

Interference paint is among the more popular mixed-media painting techniques because it’s a good way to add interest to highlights without too much shimmer. The paints can also be mixed with gels and mediums, according to one watercolor artist.
