Abstract

This study investigated the influence of various D65 simulators on visual color matching seen under five D65 simulators. These five D65 simulators were categorized by CIE No. 51 method from A to D. The gray scale rating method was used to assess the visual difference of 77 textile metamers. The instrumental color difference of each metamer was calculated using SPD of CIE illuminant D65 and real SPDs of D65 simulators. The performance factor (PF/3) was used to indicate the agreement between visual differences under five D65 simulators as well as instrumental color difference and visual difference. The observer accuracy and observer repeatability were also analyzed by PF/3 measure. The experiment results showed that the visual data obtained from category A and B D65 simulators had a good agreement in PF/3 measure. The results also indicated that better agreement between instrumental and visual color difference was obtained if the real SPDs of D65 simulator were used instead of the CIE illuminant D65 data. The general color rendering index, Ra, for each D65 simulator was calculated by CIE No. 13.3 method. However, this index was inconsistent with MI(vis) in CIE No.51 method.
