Disclosed is a method for producing a color filter comprising the steps of: forming a colored coating film on a substrate by using a colored composition comprising a pigment, a monomer having an ethylenically unsaturated double bond and a photopolymerization initiator; irradiating a filter segment or an area to be served as a black matrix on the colored coating film with an excimer laser having a wavelength of 308 nm (XeCL) so that the integrated exposure amount becomes 1 to 150 mJ/cm2, thereby curing the filter segment or the part; removing an uncured area on the colored coating film to form the filter segment or the black matrix; and repeating the aforementioned steps several times to form a filter segment having at least two colors and/or a black matrix. Also disclosed is a colored composition comprising a pigment, a monomer having an ethylenically unsaturated double bond and a photopolymerization initiator, which is intended to be used for the production of the color filter.
