Zusammenfassung:The present invention discloses a method for performing color measurement using a standard light source color matching observation box. The method comprises: arranging a halogen tungsten lamp and a light filter in the color matching observation box for cooperation, wherein the light ray of the halogen tungsten lamp emits a main body radiation light ray through the light filter; arranging a plurality of narrow-wave LED light sources of different light-emitting wavelengths to emit a compensation light ray; mixing the main body radiation light ray and the compensation light ray in the color matching observation box into a mixed light ray that uniformly simulates a standard D illuminant; and performing a color measurement on a measured object in the color matching observation box by the mixed light ray. After the present invention uses an LED lamp of a different light-emitting wavelength for compensation, the quality of the light source is
