Zusammenfassung:The object of the present invention is to provide a coloring composition containing a perylene-based compound such as C.I. pigment violet 29 while achieving high dispersion into a glycol-based solvent, the coloring composition being usable in a display production process without provoking insufficient resist curing or a drop in spectral purity. The coloring composition of the present invention contains a sulfonate compound represented by formula (1), and C.I. pigment violet 29. Formula (1): A-SO3M.nH2O [In the formula (1), A represents a hydrocarbon group having 1 to 20 carbons, optionally having a halogen, a boron, a nitrogen, a sulfur, a phosphorus, or an oxygen in the structure, M represents one equivalent of a cation having a valence of 1 to 3 excluding H, and n represents an integer from 0 to 5].
