Provided are a color filter pigment composition, a color composition, and a color filter using the same, which have a high brightness and a high contrast ratio and do not cause crystal precipitation of a diketopyrrolopyrrole pigment even in a heating process. . SOLUTION: C. I. Pigment Red 254 and a diketopyrrolopyrrole pigment having A and B in the phenyl ring. A and B are each independently a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, an alkyl group having 1 to 4 carbon atoms, an alkoxyl group having 1 to 4 carbon atoms, a cyano group, -CF3, or -CON (R1 ) R2 and at least one of A and B is -CON (R1) R2. C. I. It is related with the diketopyrrolopyrrole pigment composition for color filters whose mass ratio of pigment red 254 and said diketopyrrolopyrrole pigment derivative is 97: 3-85: 15.
