Because it dries translucent and resists oxidation, the medium preserves colour integrity and can be used in washes, glazes, or applied over dry paint for concentrated shimmer. It works especially well with transparent colours and in small amounts can create significant visual impact.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this medium change the look of acrylic paint?\u003c\/h3\u003e\n\u003cp\u003eWhen mixed into or layered over acrylic colours, the iridescent medium imparts a pearlescent sheen and subtle colour-shifting highlights that read as metallic or nacreous light.
