The Impact of Hue Differences between Two Color Schemes on Color Harmony

<p>  Color harmony in the apparel field is very important, and many color harmony theories have been proposed. Within these theoretical frameworks, hue harmony is explored in the context of identical harmony, similar harmony, and contrast harmony.</p><p>  In this experiment, we compared the harmonic ranges for L^*, a^*, b^* color space of the well-known Moon-Spencer's harmonic theory, Ostwald's harmonic theory, and PCCS harmonic theory. As a result, it was confirmed that there was no equality of hue intervals and that the harmonic range was unclear.</p><p>  Furthermore, we created a color chart sample with 20 equally divided hue angles, and conducted a visual evaluation of hue harmony in a two-color scheme. A total of 40 colors, 20 in the high-saturation area and 20 in the high-lightness area, were created, and two-color schemes were used for the upper and lower areas. Four hundred samples in the high-saturation area and 400 samples in the high-lightness area were presented against an N6 gray background. The participants in the experiment were 200 female university students. They were asked to respond to the degree of harmony on a 6-point scale.</p><p>  The results showed that the same hue was the most harmonious for both high saturation and high lightness, and the rating decreased as the hue angle between the two colors increased. No contrast harmony region existed.</p><p>  Warmer colors were placed on the upper side, while colder colors were positioned on the lower side for both high saturation and high lightness. The evaluations were higher with an increase in warmth. The overall evaluation of the color scheme was higher for high lightness than for high saturation.</p>
