２．前記ジケトピロロピロール系顔料の全顔料に対する含有率が５〜４０質量％であることを特徴とする前記１項に記載の赤色着色剤組成物。
３．前記アントラキノン系顔料の全顔料に対する含有率が５０〜８５質量％であることを特徴とする前記１、２項のいずれかに記載の赤色着色剤組成物。
４．前記黄色顔料の全顔料に対する含有率が２〜２５質量％であることを特徴とする前記１〜３項のいずれかに記載の赤色着色剤組成物。
５．前記ジケトピロロピロール系顔料がピグメントレッド２５４であることを特徴とする前記１〜４項のいずれかに記載の赤色着色剤組成物。
６．前記アントラキノン系顔料がピグメントレッド１７７であることを特徴とする前記１〜５項のいずれかに記載の赤色着色剤組成物。
７．前記黄色顔料がピグメントイエロー８３、ピグメントイエロー１３９のいずれかであることを特徴とする前記１〜６項のいずれかに記載の赤色着色剤組成物。
８．前記ジケトピロロピロール系顔料がピグメントレッド２５４であり、前記アントラキノン系顔料がピグメントレッド１７７であり、かつ前記黄色顔料がピグメントイエロー１３９であって、ピグメントレッド１７７の全顔料に対する含有率が６０〜８５質量％であることを特徴とする前記１〜７項のいずれかに記載の赤色着色剤組成物。
９．１色または複数色の画素がパターン状に設けられたカラーフィルターであって、前記の画素は着色層を有し、該着色層のうち少なくとも１色は前記１〜８項のいずれかに記載の赤色着色剤組成物により形成されたものであることを特徴とするカラーフィルター。
As a result of intensive studies to solve the problems of the prior art, the present inventors have found the following red colorant composition.

4). 4. The red colorant composition as described in any one of 1 to 3 above, wherein a content ratio of the yellow pigment to all pigments is 2 to 25% by mass.
5. 5. The red colorant composition as described in any one of 1 to 4 above, wherein the diketopyrrolopyrrole pigment is Pigment Red 254.
6). 6. The red colorant composition as described in any one of 1 to 5 above, wherein the anthraquinone pigment is Pigment Red 177.
7). 7. The red colorant composition as described in any one of 1 to 6 above, wherein the yellow pigment is any one of Pigment Yellow 83 and Pigment Yellow 139.
8). The diketopyrrolopyrrole pigment is Pigment Red 254, the anthraquinone pigment is Pigment Red 177, and the yellow pigment is Pigment Yellow 139, and the content ratio of Pigment Red 177 to all pigments is 60 to 85. The red colorant composition as described in any one of 1 to 7 above, wherein the red colorant composition is% by mass.
9.1 A color filter in which pixels of one color or a plurality of colors are provided in a pattern, wherein the pixel has a colored layer, and at least one of the colored layers is any one of 1 to 8 above. A color filter formed of the red colorant composition described above.
