The present invention addresses the problem of reducing the viscosity of a coloring composition containing a pigment. A coloring composition includes a compound represented by formula (I) and a pigment. [In formula (I), L1 represents a group represented by formula (ph1), and R1-R4 each independently represent a hydrogen atom, an optionally substituted hydrocarbon group, a heterocyclic group,-SO3N (R5) 4, a cyano group, or a halogen atom. In the formula, at least one of R1-R4 is a hydrocarbon group having one or more-SO3N (R5) 4 as a substituent, or-SO3N (R5) 4. R5 represents a hydrogen atom or a hydrocarbon group, and a plurality of R5 may be the same or different. ] 本发明的课题在于实现包含颜料的着色组合物的低粘度化。一种着色组合物，包含式(I)表示的化合物和颜料。[式(I)中，L1表示式(ph1)所示的基团，R1～R4各自独立地表示氢原子、可以具有取代基的烃基、杂环基、－SO3N(R5)4、氰基、或卤素原子。其中，R1～R4中的至少一者为具有1个以上－SO3N(R5)4作为取代基的烃基或－SO3N(R5)4。R5表示氢原子或烃基，多个R5可以相同或不同。]
