Abstract
Pearls have attracted attention for their elegant beauty. The unique luster of pearls is the result of complex optical phenomena caused by their multilayer structure which creates a lustrous appearance. Our aim was to apply the same lustrous effect to base makeup products. We conducted research on the influence of the optical phenomena of pearls embodied on a human face using a 3DCG simulation. At first, we were able to successfully generate facial images using a simulation of the optical phenomena of pearls such as blurring and interference. Following that, we evaluated 3DCG face images by surveying 215 women, changing each component's parameter. The images which synthesized blurring phenomena received the highest ratings for their attractiveness and visual sensory evaluation such as finishing, skin color preference and translucency. Finally, we examined the association between the optical phenomena of pearls, the visual sensory evaluation factors, and attractiveness value. We found that blurring is the most influential factor among the optical phenomena of pearls and attractiveness value. The results indicate that the influence of blurring is a valuable indicator for the development of base makeup that has a pearly appearance.
