To provide a colorant capable of producing a coating film with enhanced green spectral characteristics.SOLUTION: A colorant of the present invention contains a compound represented by formula (I). 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 inclusive. [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)].SELECTED DRAWING: None 【課題】Ｇｒｅｅｎ分光特性が高められた塗膜を作製できる着色剤を提供する。【解決手段】本発明の着色剤は、式（Ｉ）で表される化合物を含む着色剤であり、前記着色剤中の式（Ｉ）で表される化合物が有するＡｌ原子の個数に対する式（Ｔ－２）で表される基の数の比が、０．１以上３以下であることを特徴とする。TIFF2024043497000068.tif47140［式（Ｉ）中、Ｒ1及びＲ2は、互いに独立に、水素原子、ヒドロキシ基、－Ｒ13又は－Ｏ－Ｒ13を表す。Ｒ1及びＲ2の少なくとも一方が－Ｒ13又は－Ｏ－Ｒ13を表す場合、Ｒ1及びＲ2は互いに結合して環を形成してもよい。環Ｔ1、環Ｔ2、環Ｔ3及び環Ｔ4は、互いに独立に、式（Ｔ－１）又は式（Ｔ－２）で表される基を表す。］【選択図】なし
