To provide a coloring composition and colorant, which enable fabrication of a coating film with a high transmittance at 630-nm wavelength.SOLUTION: A coloring composition and colorant of the present invention contain a compound represented by formula (I). [In formula (I), R1 and R3 independently represent a hydrocarbon group that may have a substituent, heterocyclic group, cyano group, or halogen atom, R2, R4, and R5 independently represent a hydrogen atom, hydrocarbon group that may have a substituent, heterocyclic group, cyano group, or halogen atom. X1 represents a substituent or hydrocarbon group that may have a substituent, and n represents an integer from 0 to 4. When n represents an integer of 2 or greater and X1 is bonded to an adjacent carbon atom, X1 bonded to the adjacent carbon atom may be bonded to each other to form a ring. -CH2- contained in the ring skeleton may be replaced with -O-, -CO- or -NH-, and -CH= contained in the ring skeleton may be replaced with -N=. ]SELECTED DRAWING: None 【課題】本発明は、６３０ｎｍにおける透過率が高い塗膜を作製できる着色組成物及び着色剤を提供することを目的とする。【解決手段】本発明の着色組成物及び着色剤は、式（Ｉ）で表される化合物を含むことを特徴とする。TIFF2024014738000050.tif2192［式（Ｉ）中、Ｒ1及びＲ3は、それぞれ独立して、置換基を有していてもよい炭化水素基、複素環基、シアノ基、又はハロゲン原子を表し、Ｒ2、Ｒ4及びＲ5は、それぞれ独立して、水素原子、置換基を有していてもよい炭化水素基、複素環基、シアノ基、又はハロゲン原子を表す。Ｘ1は、置換基或いは置換基を有していてもよい炭化水素基を表す。ｎは０～４の整数を表す。ｎが２以上の整数を表し、且つＸ1が隣接する炭素原子に結合している場合、隣接する炭素原子に結合するＸ1は互いに結合して環を形成してもよい。該環の骨格に含まれる－ＣＨ2－は、－Ｏ－、－ＣＯ－又は－ＮＨ－に置き換わっていてもよく、該環の骨格に含まれる－ＣＨ＝は、－Ｎ＝に置き換わっていてもよい。］【選択図】なし
