Disclosed is a fine diketopyrrolopyrrole pigment composition which enables achievement of a good contrast ratio. Generation of undesired matter during a heating step of a red color film containing the pigment composition is remarkably reduced when compared with the conventional ones. Also disclosed are a color composition using the diketopyrrolopyrrole pigment composition, a red color film and a color filter. Specifically disclosed is a diketopyrrolopyrrole pigment composition obtained by reacting 1 mole of a succinic acid diester with 2 moles in total of mixed nitriles having specific structural formulae. Also specifically disclosed are a color composition using the diketopyrrolopyrrole pigment composition, a red color film and a color filter.
