摘要：

In this study, we quantitatively expressed the change in perceived whiteness of whitish surfaces under 3000 K and 6700 K fluorescent lamps. The experimental results of the previous study plotted in the CIECAM02 (a, b) plane were well fitted by a bivariate normal distribution. Furthermore, we conducted the experiment to determine the relative values of perceived whiteness under these fluorescent lamps. The perceived whiteness of a reflectance standard under a pseudo-D65 fluorescent lamp was set to 100, and the results showed that the relative whiteness level was 74 and 89 under 3000 K and 6700 K lamp, respectively. We proposed a method to calculate the relative value of perceived whiteness of a certain whitish surface under any light source.
