The purpose of the present invention is to provide a colorant capable of producing a coating film having enhanced green spectral characteristics. The colorant of the present invention contains a compound represented by formula (I) and is characterized in that the ratio of the number of groups represented by formula (T-2) to the number of Al atoms in the compound represented by formula (I) in the colorant is from 0.1 to 3. [In formula (I), R1 and R2 each independently represent a hydrogen atom, a hydroxy group, -R13, or -O-R13. When at least one of R1 and R2 represents -R13 or -O-R13, R1 and R2 may bond to each other to form a ring. Ring T1, ring T2, ring T3, and ring T4 each independently represent a group represented by formula (T-1) or formula (T-2).].
