Antique Copper Pearl is a metallic paint which has a deep reddish brown metallic shimmer. All of the paints in our metallic and opal series can be mixed together to create unique metallic effects. In order to maintain the metallic effects when mixing with other colors, choose from the transparent paint line. Semi-transparent and opaque paints can and will obscure the metallic qualities. The metallic pigment particles are heavy and will settle easily if melted in a container, so make sure to stir the metallic paints when using to get good pigment distribution.t.
