Abstract

Purpose : To conduct electroencephalography (EEG) and visual evoked potentials (VEPs) measurements to establish quantitative data on brainwave responses to changes in eyeshadow color, specifically the area ratio of red (R) and blue green (BG) eyeshadows.
Methods : A study was conducted on 60 males and females in their 20s using R, BG eyeshadow to determine brainwave responses via spontaneous EEG and VEPs while presenting stimuli with changes in area. The analysis focused on brainwave responses to changes in area.
Results : The brainwave responses to color stimuli demonstrated the maximum activity in the occipital lobe. Specifically, the results of the EEG analysis indicated the highest level of psychological relaxation response at the golden ratio (1.61) of the eyeshadow area. Furthermore, when participants wore BG eyeshadow, their brainwave responses remained stable, with consistent alpha wave activation. The presentation of stimuli using only the R eyeshadow resulted in a significant increase in arousal and attention levels among the participants. Perceptual responses exhibited variations based on the ratio of the main color and point color in the color contrast, and rapid VEPs responses were observed specifically under high saturation conditions. Furthermore, the study revealed a high correlation between the brainwave response results and color images, indicating that an optimal ratio of color areas can maximize the impact of the color image.
Conclusion : The results of this study suggest that by adjusting the area ratio of colors, it is possible to scientifically determine and achieve the desired color effects in color planning. The brain cognitive responses, resulting from variations in eyeshadow area, can serve as valuable quantitative data for image-making purposes, and can be applied to various fields in the beauty industry to expand their usability
