Metallic paint coatings can add a vibrancy and visual appeal to architectural projects because of the way visible light reflects off the metallic flakes. But the same qualities creating depth and brilliance also may cause variations in appearance within a project or even within a single part. The question for architects, owners, contractors and material suppliers is how to minimize the risk of metallic variation and achieve the desired design. The reflective property of metallic flakes means the same metallic painted surface will look different depending on the viewing angle, the angle of the light source (the sun), and the intensity and type of the light source. In addition, the general orientation of the metallic flakes in the paint will affect the brightness of the color. Sometimes, this is referred to as the "flop of the flake"-the undesirable but necessary reality of metallic paints.
