PROBLEM TO BE SOLVED: To provide a coloring composition using a salt-forming compound, which is soluble in a solvent and can be used as a bright red dye, a coloring composition for a color filter, which is excellent in brightness, heat resistance, and a contrast ratio when used for a color filter, and a color filter having no generation of foreign substances on a coating film.SOLUTION: The coloring composition comprises a salt-forming compound of a cationic cyanine dye represented by general formula (1-1), and an organic solvent. In the formula, A1 and A2 each independently represent -CR12(R13)- or -S-; R1 to R11 each independently represent H, a substituted or unsubstituted alkyl group or the like; R12 and R13 each independently represent a substituted or unsubstituted alkyl group or the like; and Anion- represents a specific sulfate anion. |
