To provide a color material composition which is excellent in color development and light fastness and excellent in thermal stability even in the presence of a protic polar solvent.SOLUTION: A color material composition comprises a compound represented by formula (1), and a compound whose proton dissociation energy in alcohol is in the range of 285-335 kcal/mol. (In the formula, R1 and R2 are each independently a C1-12 alkyl group; R3 is a substituted/unsubstituted phenyl group or the like; R4 is a C1-4 alkyl group or the like; and R5 is a C1-12 alkyl group, benzyl group, dialkylamino group, diphenylamino group, or the like.)SELECTED DRAWING: None 【課題】プロトン性極性溶媒存在下でも熱安定性に優れ、発色性かつ耐光性に優れた色材組成物を提供すること。【解決手段】式（１）で表される化合物とアルコール中のプロトン解離エネルギーが２８５～３３５ｋｃａｌ／ｍｏｌの範囲にある化合物とから構成される色材組成物である。TIFF2022113649000030.tif4848（Ｒ１およびＲ２は、独立して、炭素数１～１２のアルキル基；Ｒ３は、置換／無置換のフェニル基等、Ｒ４は、炭素数１～４のアルキル基等、Ｒ５は、炭素数１～１２のアルキル基、ベンジル基、ジアルキルアミノ基またはジフェニルアミノ基等）【選択図】なし
