This study investigates the influence of various D65 simulators on visual colour matching. Spectroradiometric measurements of D65 simulators and visual assessments were obtained. The spectral power distributions of three D65 simulators were measured by spectroradiometer in a colour viewing cabinet. Based on the measured spectral power distributions, the quality of the D65 simulators were assessed using CIE No.51.2 and CIE No. 13.3 methods. For visual assessment, the Davidson and Hemmendinger colour rule, which is composed of highly metameric pairs, was used in this study. The colorimetric match points and visual match points under three D65 simulators were determined. Pair-comparison t-tests were also used to examine the statistically significant differences among visual match points. The results show that various D65 simulators influence visual colour judgement of metameric pairs. The correlation between quality rating of D65 simulators under these two CIE methods and visual assessment was evaluated.
