The present invention relates to a method for analyzing the color of a color alloy and, more particularly, to a method for analyzing the color of a color alloy wherein, on the basis of the fact that a different color appears according to the composition of an alloy, the wavelength-wise reflectance related to a color, which is held according to each alloy composition, and that related to a color, which is held by a measurement object that is to be measured, are compared, thereby determining the color held by the measurement object. A method for analyzing the color of a color alloy according to the present invention may comprise the steps of: charging a measurement object and a reference object into a sample charging unit of a spectrophotometer; emitting light to the reference object and to the measurement object, using a light source of the spectrophotometer, and reflecting the same; measuring the wavelength-wise reflectance while changing the wavelength of the light, which is directed from the light source to the measurement object and to the reference object, by a detection unit of the spectrophotometer; calculating the absolute value of the difference between the measured wavelength-wise reflectances of the measurement object and of the reference object, as the deviation value, and calculating the average value thereof; dividing the average value by the reflectance value of the reference object, thereby obtaining the mean deviation ratio of reflectances; and comparing the mean deviation ratio with a preset reference value, thereby determining whether the colors are the same or not by an operation unit. |
