An objective of the present invention is to improve solubility and heat resistance of a yellow compound with respect to an organic solvent (PGMEA or the like), and to provide provides a coloring composition, a colorant for a color filter, and the color filter, which have excellent color characteristics. Provided is a compound is represented by general formula (1). In formula (1), each Q independently represents a group represented by formula (2), n represents an integer of 2-10, and L represents a group of 2-10; each of R^1-R^9 independently represents H, a hydroxyl group, a halogen atom, an amino group, a sulfonyl group, an alkyl group, an alkenyl group, an alkoxy group, an acyl group, -O-, an aromatic hydrocarbon group, a heterocyclic group, or the like, and can form a ring by bonding adjacent groups to each other. Each Z independently represents a divalent group or a trivalent group and represents an amino group, an alkylene group, a group containing -O- or a single bond, and a plurality of Qs are bonded to each other via L or Z.
