Abstract: Traditional color reproduction technology based on the Metamerism principle, the
disadvantage is that different observer condition leads to different color appearance.To fulfill the
color consistency, the spectrum reflectance of the object color sample need to be reconstructed.
The principal component analysis makes use of the linear combination of a few principal
components to reconstruct the spectral reflectance of sample. This paper analyzes the 31*31
matrix of Munsell spectral data by the principle component analyze method and achieves the
principal component for spectrum reflectance. The numbers of principal components are
identified as six by discussing the variance contribution rate. Spectral reconstruction of four
Munsell testing samples makes use of first six principal components, which has met the accuracy
requirements. Research shows that the reconstruction of spectral accuracy decreased when
training samples and testing samples belong to the different database. © (2013) Trans Tech
