摘要：The colorimetric error depends on the spectrophotometric inaccuracy. In this paper, a ‎new method is introduced for determining the relationship between spectrophotometric ‎error and colorimetric inaccuracy. The error propagation in colorimetric parameter ‎calculation is evaluated using a linear relation between variance of reflectance spectra ‎and CIE tristimulus values. This linear formula calculates the variance of CIE tristimulus ‎values from the variance of reflectance spectra with sufficient accuracy. In addition, the ‎effect of illuminants and standard colorimetric observers on the error propagation from ‎spectral data into CIE tristimulus values is studied using the proposed relationship. The ‎results indicate that the effect of illuminants is more than the effect of standard observer. ‎In addition, the Standard deviation of CIE tristimulus values depends on their respective ‎coefficients.‎
