Zusammenfassung:This report presents a study to evaluate the practical feasibility of using a spectrometer outfitted with an integrating sphere for the quantitative measurement of color. The precision of the measurement was evaluated and found to be very high. The accuracy was evaluated using nominal values for L*a*b* (color space) from international paint suppliers. The results demonstrate the value of using a spectrophotometer for color measurements. The experimental L*a*b* values for a large number of colors from the federal color standard listing are reported.
