To provide a coloring composition capable of obtaining a photosensitive coloring composition having an appropriate viscosity and satisfactory viscosity stability (dispersion stability), which can form a film having less foreign matter generation, less residue, and suppressed surface roughness.SOLUTION: The coloring composition contains organic pigment (A) and resin type dispersant (B). The organic pigment (A) includes one or more selected from zinc phthalocyanine pigment (A1) and aluminum phthalocyanine pigment (A2). The content of organic pigment (A) is 40 to 90% by mass in 100% by mass of the non-volatile content of the coloring composition. The resin type dispersant (B) contains an aromatic carboxylic acid structure, and a resin type dispersant (B1) having a vinyl polymer moiety which has a (meth) acryloyl group.SELECTED DRAWING: Figure 1 【課題】本発明は、適度な粘度と良好な粘度安定性（分散安定性）を有し、異物の発生の少なく、さらに残渣が少なく、かつ表面の粗さが抑制された被膜を形成できる感光性着色組成物が得られる着色組成物の提供を目的とする。【解決手段】有機顔料（Ａ）と、樹脂型分散剤（Ｂ）とを含む着色組成物であって、有機顔料（Ａ）は、亜鉛フタロシアニン顔料（Ａ１）およびアルミニウムフタロシアニン顔料（Ａ２）から選ばれる１種以上を含み、有機顔料（Ａ）の含有量は、前記着色組成物の不揮発分１００質量％中、４０〜９０質量％であり、樹脂型分散剤（Ｂ）は、芳香族カルボン酸構造、および（メタ）アクリロイル基を有するビニル重合体部位を有する樹脂型分散剤（Ｂ１）を含む、着色組成物。【選択図】図１
