Abstract: Provided are a method for preparing a pigment composition, which enables a proper amount of a pigment composition to be timely produced and is small in quality deviation of products in lots, and a colored composition obtained thereby, which forms a color filter having a high contrast ratio. The method for preparing a pigment composition comprises a step of kneading a mixture including an organic pigment, water-soluble inorganic salts, water-soluble organic liquid, and a resin using a continuous kneader(10). The kneader(10) comprises a driving shaft(121), an annular fixed disc(21), a rotary disc(23) that has the same center with the fixed disc(21) and rotates around the driving shaft(121) integrally, and a dedifferentiated space formed in a gap between the fixed disc(21) and the rotary disc(23). The resin is a rosin resin.
