Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a green semi-crude of halogenated metal phthalocyanine for a color filter, a green pigment composition, in which the semi-crude produced by this method is used together with a yellow pigment, and to provide the color filter in the green pixel part of which the green pigment composition is used to make the contrast of a coating film superior. SOLUTION: The green semi-crude for the color filter is produced, by dry-crushing the crude pigment of halogenated metal phthalocyanine, having Al, Si, Sc, Ti, V, Mg, Fe, Co, Ni, Cu, Zn, Ga, Ge, Y, Zr, Nb, In, Sn or Pb as a central metal in the presence of water-soluble inorganic salt.
