| Summary: | 博士 === 大同大學 === 設計科學研究所 === 107 === Over the past few years, while many studies have been made on color harmony, most used the planar color configuration, which is not in line with the design requirements of real-life products. Therefore, this study used 11 basic colors and 5 kinds of color scheme techniques to derive 141 color combinations applied upon a physical 3D color configuration to see the phenomena of color harmony.
The phenomenon of color harmony for 3D color configuration was found that the observer's evaluation for color harmony will not be affected by the exchange of the main and secondary colors. This phenomenon can also explain that the size of the area corresponding to the main and secondary colors doesn't affect the color harmony. For color scheme technique, “achromatic-achromatic combination” was the most harmonious technique, “same tone with different hue” was the most disharmonious. In the discussion of the relationship between color preferences and color harmony, it can be seen that the more harmonious the color combination, the more like.
However, the results of this study also showed that color harmony on the 3D color configuration is different from that of the planar color configuration, which can be explained by 4 phenomena and a quantitative model. The first phenomenon is the combination color of achromatic color with achromatic color, and this phenomenon is mainly affected by the difference in lightness. When the lightness difference between the two colors is smaller, it is more harmonious. The second phenomenon is the combination of achromatic color with chromatic color. When the sum of the lightness of the two colors is larger, it tends to be more harmonious. The third phenomenon is a color combination with chromatic color and chromatic color, and the hue difference is greater than 90∘. When the hue difference between the two colors is greater than 90°, the sum of the lightness and chroma are larger, while the difference of the yellowness-blueness is smaller, and the sense of harmony is better. The fourth phenomenon is a color combination with chromatic color and chromatic color, and the hue difference is less than or equal to 90°. When the hue angle difference of the color combination is less than or equal to 90°, the hue angle difference is smaller, the lightness sum is larger, and it tends to be more harmonious. This study also developed a color harmony model that conforms to the 3D color configuration and performs well.
