Spectral estimation of chromatically adapted corresponding colors

This paper reviews the estimation of spectral reflectance for corresponding colors in XYZ color space, including both corresponding color data sets and chromatically adapted colorimetry. For use in color management workflows, the performance of an inverse transform of the chromatically adapted data was evaluated using spectral estimation. These estimated spectra were then evaluated against the estimated spectral reflectances of reference corresponding color data to analyze the similarity. The results show that established methods using PCA can be used to obtain good spectral estimates, and the methods described in this paper can be implemented in a color managed workflow where spectral processing and output are desired
