The invention aims to provide a metal phthalocyanine dye mixture having excellent solubility in an organic solvent, which can be formed into a thin film. Provided are a metal phthalocyanine dye mixture contains at least phthalonitrile, a compound represented by the following formula (I), a compound represented by the following formula (II), and a metal or a metal compound, and a curable composition containing the metal phthalocyanine dye mixture, a color filter containing the curable composition, and a method for producing the color filter: wherein, in formulae (I) and (II), R1 represents a substituent; n represents an integer of from 0 to 3; X represents —S—, —SO2—, or —SO2N(R4)—; R4 represents a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, or a heterocyclic ring group; R2 represents an alkyl group, an alkenyl group, an aryl group, or a heterocyclic ring group; R3 represents a substituent; m represents an integer of from 0 to 3; and Z represents —SO3M or —(X1-A) group; wherein X1 has the same definition as X; A represents an optionally substituted group having at least one selected from —COOM, —SO3M, —SO2NH—R5, —SO2NHCOR6, —CONHSO2—R7, and —SO2NHSO2—R8; M represents a hydrogen atom, or an alkali metal or organic base group for neutralization of charges; and R5, R6, R7, and R8 each independently represents an alkyl group, an alkenyl group, an aryl group, or a heterocyclic ring group.
