• In the previous study (Sobagaki et al., 1983), we applied principal component analysis to the measured spectral reflectance distributions (SRDs) of the JIS Z 8721 color chips, and proposed a reconstitution method for deriving the SRD corresponding to any specified Munsell renotation. However, the SRD generated by the method did not satisfy the object color condition (0≦ρ(λ)≦1) for highly saturated colors where ρ(λ) denotes to the SRD. In this paper, we derive the SRD satisfying the object color condition in the region of highly saturated colors. The SRD of highly saturated colors is given by combining the SRD obtained by the reconstitution method with that of optimal colors and with those of achromatic colors. This method was applied to all the highly saturated colors specified in JIS Z 8721 to provide the standard colorimetric values under CIE standard illuminant Don.
