1. A colored photosensitive resin composition comprising a colorant, a resin, a polymerizable compound, and a polymerization initiator,
the colorant comprising a compound represented by formula (1) and α-type copper phthalocyanine pigment, which is selected from the group consisting of C. I. Pigment Blue 15, C. I. Pigment Blue 15:1, and C. I. Pigment Blue 15:2, and/or β-type copper phthalocyanine pigment, which is selected from the group consisting of C. I. Pigment Blue 15:3 and C. I. Pigment Blue 15:4:
 wherein
R41 to R44 each independently represent a hydrogen atom, a saturated hydrocarbon group having 1 to 20 carbon atoms, an aromatic hydrocarbon group having 6 to 20 carbon atoms and optionally having a substituent, or an aralkyl group having 7 to 30 carbon atoms and optionally having a substituent; the substituent which is optionally contained in the aromatic hydrocarbon group and the aralkyl group may be —SO3− or —SO2—N−—SO2—Rf; a hydrogen atom contained in the saturated hydrocarbon group is optionally replaced with a substituted or unsubstituted amino group or a halogen atom; when the number of carbon atoms of the saturated hydrocarbon group is 2 to 20, —CH2— contained in the saturated hydrocarbon group is optionally replaced with at least one of —O— and —CO—, provide that in the saturated hydrocarbon group having 2 to 20 carbon atoms, —CH2— and —CH2— adjacent to each other are not simultaneously replaced with —O—, and terminal —CH2— is not replaced with —O— or —CO—; R41 and R42 are optionally bonded to each other to form a ring together with a nitrogen atom to which they are attached; R43 and R44 are optionally bonded to each other to form a ring together with a nitrogen atom to which they are attached;
R47 to R54 each independently represent a hydrogen atom, a halogen atom, a nitro group, a hydroxy group, —SO3−, —SO2—N−—SO2-Rf, or a saturated hydrocarbon group having 1 to 20 carbon atoms; —CH2— constituting the saturated hydrocarbon group is optionally replaced with at least one of —O— and —CO—; R48 and R52 are optionally bonded to each other to form —NH—, —S—, or —SO2—, provide that in the saturated hydrocarbon group, —CH2— and —CH2— adjacent to each other are not simultaneously replaced with —O—, and terminal —CH2— is not replaced with —O— or —CO—;
a ring T1 represents an aromatic heterocycle having 3 to 10 carbon atoms; the aromatic heterocycle optionally has a saturated hydrocarbon group having 1 to 20 carbon atoms, a substituted or unsubstituted amino group, or an aromatic hydrocarbon group having 6 to 20 carbon atoms and optionally having a substituent; the substituent which is optionally contained in the aromatic hydrocarbon group may be —SO3− or —SO2—N−—SO2—Rf;
Mr+ represents an r-valent metal ion;
k represents the sum of the number of —SO3− and the number of —SO2—N−—SO2-Rf in the compound represented by formula (1);
r represents an integer of 1 or more;
Rf represents a fluoroalkyl group having 1 to 12 carbon atoms; and
the compound represented by formula (1) has at least one —SO3− or —SO2—N−—SO2-Rf.
