The present invention improves the solubility and heat resistance of a yellow compound in an organic solvent (such as PGMEA). This invention provides a coloring composition having excellent color characteristics, a coloring agent for a color filter, and a color filter. This invention is a compound 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 2-10 valent groups. R1-R9 each 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; Z each independently represents a divalent group or a trivalent group and represents an amino group, an alkylene group, -O- or a single bond group, and a plurality of Qs are bonded to each other via L or Z.].
