A metallic effect pigment comprising at least three layers: A) a layer A which comprises at least one metal MA and has an average oxygen content OA, based on the total amount of MA and OA in the layer A, B) a layer B comprising at least one metal MB and having an average oxygen content OB of 0 to 77 atom %, more particularly of 0 to 58 atom %, based on the total amount of MB and OB in the layer B, C) a layer C which comprises at least one metal MC and has an average oxygen content OC, based on the total amount of MC and OC in the layer C, the average oxygen content OAC in layers A and C being determined in accordance with the formula (I) O AC = 1 2 ( O A M A + O A + O C M C + O C ) ( I ) and being situated within a range from 2 to 77 atom %, more particularly from 25 to 58 atom %. The disclosure further relates to processes for preparing this effect pigment and also to its use.
