A method for producing a colored low-polarizing film for sunglasses comprising the steps of: determining desired values of the polarizing degree, the transmittance, and the color tone (L*, a*, b*) of a colored low-polarizing film, calculating an amount of a dichroic organic dye composition and a coloration organic dye composition to be used to obtain the desired values without considering a color change brought about by a simultaneous dyeing of the dichroic organic dye composition and the coloration organic dye composition, wherein the dichroic organic dye composition comprises a combination of dichroic organic dyes having a dichroic ratio of 13 or higher, used in an amount necessary to keep the polarization degree of the film from 30% to less than 90%, wherein the coloration organic dye composition comprises a combination of dyes having a dichroic ratio of 4 or less or substantially having no dichroic ratio, wherein the dichroic ratio is calculated as Az/Ax, where Ax represents the absorbance of linearly-polarized light in the maximum transmission direction, and Az represents the absorbance of linearly-polarized light in a direction perpendicular to the maximum transmission direction, measured at the maximum absorption wavelength of a polarizing film produced by using a dye or dichroic dye instead of iodine under the manufacturing conditions where the polarizing film produced by using iodine shows dichroic ratios measured at 600 nm of 60 or more, producing a first polarizing film by causing a polyvinyl alcohol film to swell with water, uniaxially stretching it, dyeing it with the calculated amounts of dichroic organic dye composition and coloration organic dye composition, and drying it, comparing the values of the polarizing degree, the transmittance, and the color tone of the produced film with the desired values, producing another polarizing film by causing a polyvinyl alcohol film to swell with water, uniaxially stretching it, dyeing it with the recalculated amounts of dichroic organic dye composition and coloration organic dye composition, and drying it, repeating the above steps until the colored low-polarizing film of a desired color that has the desired values is obtained, wherein the polarizing degree of the colored low-polarizing film is 45% to less than 90%. determining desired values of the polarizing degree, the transmittance, and the color tone (L*, a*, b*) of a colored low-polarizing film, calculating an amount of a dichroic organic dye composition and a coloration organic dye composition to be used to obtain the desired
