Abstract: The use of an effect pigment (a) comprising an aluminum-based substrate and an iron oxide coating having a red 1st order interference color in combination with a colored absorption pigment (b) for producing a coating having enhanced coloristic properties, in particular enhanced chroma, lightness and hiding power, is provided. The pigment combination of (a) and (b) is suitable for coloring plastics, a fiber, a film and a coating composition such as a paint, a printing ink, a varnish or a powder coating, preferably an automotive, an architectural or an industrial coating composition.
