This study explored the effects of color combinations and polarity on user preferences and EEG responses using an icon design for a visual display terminal. 72 college students (M=24.5 yr., SD=2.3 yr.) were tested. The seven color combinations of top 16% with rating scores (5-point scale) over 3.60 almost always included black or white as a target or background, including white-on-black, red-on-black, yellow-on-black, blue-on-white, and black-on-white; the other two preferred color combinations were yellow-on-blue and blue-on-yellow. The eight color combinations of the bottom 16% with rating scores under 2.38 almost always included green, turquoise, or purple as a target or background. Negative image polarity (higher luminance color image shown on a lower luminance color background) was preferred over positive image polarity (lower luminance color image shown on a higher luminance color background) by the subjects. The theta and alpha band power in the right hemisphere were greater than those in the left hemisphere during the experiment. There seemed to be no linear correlation between the rating scores of subjective preferences and brain wave power of theta and alpha bands, so the possibility of using brain wave power to measure subjective preference is questionable.
本研究通过视觉显示终端的图标设计，探讨了颜色组合和极性对用户偏好和 EEG 反应的影响。72 名大学生（M=24.5 岁，SD=2.3 岁）参与了测试。在评级得分超过 3.60（五分制）的前 16%的七种颜色组合中，几乎总是包含黑色或白色作为目标或背景，包括白黑、红黑、黄黑、蓝白和黑白；另外两种较受欢迎的颜色组合是黄蓝和蓝黄。在评级得分低于 2.38 的后 16%的八种颜色组合中，几乎总是包含绿色、青绿色或紫色作为目标或背景。与正像极性（低亮度颜色图像显示在高亮度颜色背景上）相比，受试者更喜欢负像极性（高亮度颜色图像显示在低亮度颜色背景上）。在实验过程中，右半球的θ和α频段的功率大于左半球。主观偏好的评分与θ和α频段的脑电波功率之间似乎没有线性相关性，因此使用脑电波功率来衡量主观偏好的可能性值得怀疑。
