Inorganic, non-quarter wave, non-uniform multi-layer effect pigments include a plate-like substrate having thereon an absorptive and optically active metal oxide layer having an optical thickness of about 20 nm to about 400 nm, A layer of low index material having an optical thickness of about 10 nm to about 500 nm on the optically active metal oxide layer and a non-layer having an optical thickness of about 50 nm to about 1000 nm on the low index material. The outermost optically active layer of absorptive high refractive index material. This multilayer effect pigment exhibits a blue reflectance (BRR) of at least 3 according to the formula BRR=(blue maximum)/(green minimum), where the blue maximum is the maximum reflectance exhibited over a wavelength of 380 nm to 450 nm, And the green minimum is the minimum reflectance exhibited over wavelengths of 450 nm to 600 nm.無機、非四分の一波、不均一多層効果顔料は、約２０ｎｍ～約４００ｎｍの光学的厚さを有する吸収性光学活性金属酸化物層をその上に含む板状基材と、この吸収性光学活性金属酸化物層上の、約１０ｎｍ～約５００ｎｍの光学的厚さを有する低屈折率材料の層と、この低屈折率材料上の、約５０ｎｍ～約１０００ｎｍの光学的厚さを有する非吸収性高屈折率材料の最外光学活性層と、を含む。この多層効果顔料は、式ＢＲＲ＝（青色最大）／（緑色最小）に従う、少なくとも３の青色反射率（ＢＲＲ）を示し、青色最大が、３８０ｎｍ～４５０ｎｍの波長にわたって示される最大反射率であり、かつ緑色最小が、４５０ｎｍ～６００ｎｍの波長にわたって示される最小反射率である。
