It is perceived at the specular angle, by observing the image of a white light source, for example, and is characterized by a distinct hue of different dominant wavelength than the hue of the paint film itself. The origin of the selective specular reflectance observed is generally considered to be reflectance from very small particle size pigments partially separated from surrounding vehicle at or near the surface. (2) Characteristic metallic luster shown by certain highly colored pigments in full strength, e.g., certain iron and phthalocyanine blues.
