Abstract
Provided is a coloring composition containing a colorant, a resin, a polymerizable compound, a photopolymerization initiator, an ultraviolet absorber, and a solvent, in which the colorant contains an unsubstituted copper phthalocyanine pigment and a halogenated copper phthalocyanine pigment, a content of the unsubstituted copper phthalocyanine pigment in a total mass of the colorant is 10% by mass or more, and a content of the halogenated copper phthalocyanine pigment in the total mass of the colorant is 40% by mass or more.
