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 illuminations, the perceived whiteness of purple and red hue samples was highly evaluated while green and blue-green hue samples were poorly 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.
