PROBLEM TO BE SOLVED: To provide a coloring composition for a color filter excellent in dispersibility, flowability, and storage stability, and further, also excellent in developability, and a color filter. SOLUTION: The coloring composition for a color filter is provided, which contains: a polyester dispersant (X) obtained by reacting a hydroxyl group in a polyol including a vinyl polymer having two hydroxyl groups at one terminal region with an acid anhydride group of a tricarboxylic acid anhydride and/or a tetracarboxylic acid dianhydride; wherein, the vinyl polymer is obtained by performing radical polymerization of an ethylenically unsaturated monomer having an ether group in the presence of a compound having two hydroxyl groups and one thiol group within a molecule; a pigment; a binder resin, an active energy ray curable monomer, an active energy ray polymerization initiator, and a solvent.
