Colored paints achieve their color effect by the addition of pigments. Pigments are colored, solid, very fine organic and inorganic particles which are insoluble in the binding material.
Metallic pigments
Aluminum platelets are added as pigment to form metallic paint.
Depending on the size and shape of the aluminum platelets, different metallic effects can be achieved:
With metallic paints however, only a light-dark light reflection effect occurs.
Colored metallic paints are produced by the extra addition of color pigments to the metallic paint.
Pearl pigments
The basis of pearl pigments is formed by mica, which is metallized with a silver or gold layer.
Depending on the angles of light and observation, the mica platelets reflect different proportions of light. Because of this, the color of the paint appears to the observer to change.
Pearl pigments produce a colored and light-dark reflected light effect.
