An object of the present invention is to provide a colored photosensitive composition capable of forming a color filter array having improved spectral characteristics. The colored photosensitive composition comprises a compound represented by the formula (I) or a salt thereof: wherein in the formula (I), Z1 and Z2 represent an oxygen or sulfur atom; R1 to R4 represents a hydrogen atom, a saturated aliphatic hydrocarbon group (which may be substituted with a hydroxyl group), an aryl group, an aralkyl group, or an acyl group; and R5 to R12 represents a hydrogen atom, a halogen atom, a (halogenated) saturated aliphatic hydrocarbon group, an alkoxyl group, a carboxyl group, a sulfo group, or an (N-substituted) sulfamoyl group, and at least one of R5 to R12 is an N-substituted sulfamoyl group.
