PROBLEM TO BE SOLVED: To provide a method for producing a curable coloring composition exhibiting little mingling of foreign matters, and to provide a color filter and a solid-state image pick-up device using the curable coloring composition and having high yield. SOLUTION: The method for producing a curable coloring composition comprises the pigment cleaning step of cleaning a pigment (A), the pigment dispersing step of dispersing the pigment (A), and the mixing step of mixing the pigment (A), an alkali-soluble resin (B), a polymerization initiator (C), a polymerizable compound (D), and a solvent (E), wherein the pigment cleaning step is a step of cleaning the pigment (A) with an ion exchange water.
