A color measuring system includes a color classifying apparatus and a color nonuniformity checking apparatus capable of measuring color nonuniformity which simplify the configuration, reduce cost, withstand mechanical vibration, and are capable of classifying the colors of objects well without limiting the light source even when its spectrum varies, and which are capaple of further improving the color classification accuracy. The color classifying apparatus includes an imaging section for imaging the reflected light from an object, a plurality of band-pass dilters each having a different band and provided between the object and the imaging section, and a classifying section for computing a classification spectrum for classification using a statistical approach from the multispectral image data on the object imaged by the imaging section and classifying the object using the classification spectrum, wherein the classifying section uses a classification judgment method most suitable for classification judgement on the object.
