372 JOURNAL OF COSMETIC SCIENCE 8A, statistically significant differences are obtained for eyeliners with different light levels, while only a marginal difference is evident between blue and dark brown eyeliners. This result indicates that perceptual eye enlargement is significantly affected by the lightness of the eyeliner. However, a distinctly different trend is evident for the perceptual sclera Figure 7. Experimental results for hue-rotated colored eyeliners and an equal-lightness achromatic eyeliner (grey). PSEs of eye size are shown in (A), and PSEs of sclera whiteness are shown in (B). The horizontal dotted line shows the baseline (data from the original stimuli are shown in Figure 1). The mean ± SE of measured PSEs for all subjects are plotted as error bars, and the statistical significance of the PSE differences from baseline tested by one-sample t-test with Holm’s correction are presented as **:p 0.01 *:p 0.05 n.s.: not significant.

373 EFFECT OF EYELINER ON THE PERCEIVED SCLERA COLOR whiteness in Figure 8B. The PSEs of sclera whiteness in standard stimuli with bluish eyeliners tend to be higher than those in images with brownish eyeliners. Statistically significant differences can be observed between navy and brown eyeliners and navy and dark brown eyeliners. This result indicates that the perceptual sclera whiteness is strongly affected by the chromaticity coordinates of the eyeliner, and a navy eyeliner is the effective color design to simultaneously achieve the perceptual eye enlargement and perceptual sclera Figure 8. Experimental results for brown and blue eyeliners with two different light levels: PSEs of (A) eye size and (B) sclera whiteness. The horizontal dotted line shows the baseline (data from the original stimuli shown in Figure 3). Mean ± SE of measured PSEs for all subjects are plotted as error bars, and the statistical significance of the PSE differences between eyeliners tested by paired t-test with Holm’s correction are presented as **:p 0.01 *:p 0.05 †: p 0.1.
