    Summary:An index for quantitative evaluation of the color discrimination property of sunglass lenses was calculated as the ratio of the color gamut area formed by the eight CIE-1974 test-color samples for the general color rendering index on the CIECAM02 colorfulness plane under the standard illuminant D65 after passing through the sunglass lenses under test to the gamut area formed by the samples on the plane under the illuminant D65. The index was validated by a very high simple correlation coefficient between the visual evaluation results and the indices of the color discrimination property. Furthermore, it was shown that blocking the spectral component around 565 nm effectively improves the color discrimination property and that a spectral transmittance factor that blocks wavelength components in a 500-nm area effectively improves color discrimination and enhances colorfulness for the color yellow simultaneously.

    Summary:This article describes a new perceived whiteness index, C/V index, which focuses on the brightness-enhancement effect of color components included in the spectral reflectance factor distribution of approximate white objects or in the spectral power distribution of illuminations. The index is developed on the basis of a color vision model. The perceived whiteness of 18 approximate white samples was evaluated, and then a predictability of the index was compared with 17 types of existing whiteness indices. As a result, the C/V index was one of the indices indicating the best predicting performance. The aforementioned findings show that the C/V index is effective in evaluating the perceived whiteness of approximate white objects and the brightness-enhancement effect of color components is an important factor in determining the perceived whiteness.

    Summary:The perceived whiteness of 12 approximate white-color samples was evaluated under four different fluorescent lamps (EXD, EXN, EXWW, and EXL) using a paired comparison method, and then an interval scale was configured. Under all illuminatons, the perceived whiteness of purple and red hue samples was highly evaluated while green and blue-green hue samples were poody evaluated. The C/V index, a perceived whiteness evaluation index, which focused on the brightness-enhancement effect of color components that were included in the approximate white objects or illuminations, showed a high correlation with the interval scale value under each illumination. Furthermore, compared to various color appearance models, the index showed a superior predicting performance. The above findings confirmed that the C/V index was effective in evaluating the perceived whiteness of approximate white objects under different illuminations, and the brightness-enhancement effect of color components was an important factor in determining the perceived whiteness.
