A process for producing a pigment composition containing a highly halogenated copper phthalocyanine, produced by halogenation of copper phthalocyanine in the presence of chlorosulfonic acid, titanium tetrachloride or a mixture of titanium tetrachloride with aluminum chloride, a highly halogenated copper phthalocyanine produced by halogenation of a copper phthalocyanine in a solid powder state, or a highly halogenated copper phthalocyanine produced by cyclization. The composition further contains at least one highly halogenated different-metalo-phthalocyanine selected from highly halogenated metalo-phthalocyanines each of which has Al, Mg, Si, Ti, V, Mn, Fe, Co, Ni, Zn, Ge or Sn as a central metal.
