a pigment;
a compound A having each of a coloring agent partial structure, an acid group or a basic group, and a curable group;
a photopolymerization initiator;
a curable compound other than the compound A; and
a resin,
wherein a content of the compound A in a total solid content of the curable composition is 1 to 15 mass %;
the coloring agent partial structure included in the compound A is a partial structure derived from a coloring agent selected from the group consisting of a benzimidazolone coloring agent, a benzimidazolinone coloring agent, a quinophthalone coloring agent, a phthalocyanine coloring agent, an anthraquinone coloring agent, a diketopyrrolopyrrole coloring agent, a quinacridone coloring agent, an azo coloring agent, an isoindolinone coloring agent, an isoindoline coloring agent, a dioxazine coloring agent, a perylene coloring agent, and a thioindigo coloring agent;
the compound A is a compound represented by any one of Formulae (A1) to (A3),

in Formula (A1), P 1 represents the coloring agent partial structure, L 11 represents an a1+1 valent linking group, L 12 represents a b1+1 valent linking group, A 1 represents the curable group, B 1 represents the acid group or the basic group, and a1, b1, n, and m each independently represent an integer of 1 or more,
in Formula (A2), P 2 represents the coloring agent partial structure, L 21 represents an a2+b2+1 valent linking group, A 2 represents the curable group, B 2 represents the acid group or the basic group, and a2, b2, and j each independently represent an integer of 1 or more, and
in Formula (A3), P 3 represents the coloring agent partial structure, L 31 represents an a3+1 valent linking group, A 3 represents the curable group, B 3 represents the acid group or the basic group, and a3 and k each independently represent an integer of 1 or more,
wherein L 11 , L 12 , L 21 , and L 31 are each independently represented by any one of Formulae (L-1) to (L-5),

in the formulae, * represents a bonding hand,
p1 represents an integer of 0 to 5 and p2 represents an integer of 1 to 6, in which p1+p2 is an integer of 2 to 6,
L 100 to L 105 each independently represent a single bond or a divalent linking group, and
X 1 , X 2 , and X 3 each independently represent —O—, —S—, or —NR L1 —, in which R L1 represents a hydrogen atom, an alkyl group, or an aryl group.

2. The curable composition according to claim 1 ,

5. The curable composition according to claim 1 ,
wherein the resin includes a resin having an acid group.

6. The curable composition according to claim 1 ,
wherein the pigment includes a chromatic pigment.

7. The curable composition according to claim 1 ,
wherein the pigment includes a green pigment.

8. The curable composition according to claim 1 ,
wherein the curable composition includes two or more kinds of the pigment.

9. The curable composition according to claim 1 ,
wherein the curable compound includes a polyfunctional polymerizable monomer.

10. The curable composition according to claim 1 , further comprising:
an organic solvent.

11. A method for producing the curable composition according to claim 1 , the method comprising:
dispersing the pigment in a presence of the compound A having each of a coloring agent partial structure, an acid group or a basic group, and a curable group, and the resin.

12. A film which is formed from the curable composition according to claim 1 .

13. A color filter comprising:
the film according to claim 12 .

14. A method for manufacturing a color filter, comprising:
