Zusammenfassung:To obtain a colored composition hardly having defects observable on a coating film and a color filter having a filter segment and/or a black matrix having hardly recognizable coating film defects. The liquid colored composition comprises a transparent resin, a coloring matter carrier composed of its precursor or its mixture, an organic solvent and a surface conditioner. The colored composition satisfies 0.08 ≤ B-A' ≤ 0.18 in which when a glass plate having 22 mm*22 mm and thickness of 0.145 mm is immersed in the liquid colored composition in 2.5 mm in the vertical direction according to a Wilhelmy flat plate method, force A (25 DEG C) measured in the stationary state of the glass plate is >=1.16 mN, force A' is obtained by subtracting the buoyancy of the glass plate from the force A and force B (25 DEG C) is measured at an instant when the glass plate is separated from the liquid colored composition in pulling up the immersed glass plate at 2.5 mm/second in the vertical direction. The color filter has a filte
