The main objective of this research is to investigate the color coordination types and their characteristics of contemporary female fashion by reviewing 'pre-a-porter Collections' of four collections (i.e., cities) - Paris, Milan, New York, London - from the periods of 2000 S/S to 2002/3 A/W. Through the review of various books and articles written on the subject, the color coordination types and their characteristics were categorized and defined. The data was collected by reviewing 'pre-a-porter Collections' magazine and total 4,269 observations were made. These in turn were categorized into eight color coordination and three color tone categories through the content analysis. Frequency analysis was used to analyse the data. The findings are as follows; First of all, there were 8 observable color coordination categories in contemporary women's fashion. The most used color coordination was chromatic & achromatic color coordination. It was followed by chromatic identical, and then by achromatic identical color coordination. These three color coordinations were the majority, comprizing 73.4％ of the total. The rest were in the order of complementary, gradation, similarity, accent. And the most used tone type was contrasting tone and followed by similar and identical. Next, the analysis of each coordination categories shows that; The chromatic identical coordination focused on presenting its own unity or break it using the contrasting color tone. Meanwhile, the achromatic identical coordination project a clean and strong feeling through black and white combination or a subtle feeling through the different material combination. The chromatic & achromatic coordination showed strong colors and contrasting tones of clear and bright colors. Meanwhile, the characteristics of complementary coordinations are that these coordinations seem to free the colors and show the subtle changes in tones very clearly. The gradation coordination was used to create a cool and lively feeling. Next, the similarity coordination seems to create feminine and warm feeling by taking advantage of similar color feelings, often through the use of warm to warm, cool to cool color matching. Lastly, the accent coordination, through the use of contrasting tones emphasizes the differences in colors, while separation coordination mostly uses black and white on various color coordinations.

As a part of the study for the materials development of compound feelings, therefore, this study investigated into the effects of the colors of warp and weft on the overall colors of fabrics, along with the visual changes of colors by the measuring angle of both warp and weft, by means of cross-dyeing of cotton/PET union fabrics. First, the dyeing of cotton and PET fabrics individually with the same color, the dyeing of PET fabrics followed by that of cotton fabrics resulted in a small difference in color than the dyeing in the reversed order. Second, in the case of the dyeing of cotton/PET union fabrics with the color of one fiber fixed and that of the other in ten colors, the color of cotton fiber, which is warp, gave much influence. In addition, the color change was remarkable among complementary colors, while it was negligible among adjacent colors. Third, in the case of dyeing of cotton/PET union fabrics with the color of one fiber fixed and that of the other in ten colors, the results were different by the measuring angle. When PET was fixed in green and cotton was dyed in ten colors, color-deepening was observed by the inclination in the direction of warp and weft without the dominance over all colors like cotton. When cotton was dyed in red and PET in ten colors, the color of PET appeared dimly in the horizontal case by the direction of the light, and red appeared as inclined in the direction of warp and weft. This is because of the dominance of cotton color over the overall color, since the density of cotton fiber, the warp of union fabrics, is higher than that of PET, the weft. Thus, this is to be considered in the selection of the warp's color. In view of the above results, the color changes are outstanding when the color of warp dominates the overall color and when the colors of warp and weft are complementary, in comparison with the case when the colors are adjacent. The colors also change by the measuring angle.

Mobile display panel is small so that users are often difficult to perceive images clearly. About image we perceive much through colors and therefore we propose color fitting approach for clear perception even on the small and low quality LCD panels. Various color modifications have been studied and used in commercial software packages. For mobile usage, our approach instantly enhances color images by modifying colors in a way to contrast differences of them. The method includes tone enhancements (which contrast dark and bright sides) and color enhancements (which reduce saturation for pure colorants). Based on color theory, our method also modifies color values towards specified complementary and preference colors. We term this color fitting. This approach enables displaying photos, multimedia messages, videos and digital media broadcasting (DMB) for better perception in real-time on mobile devices. Index Terms.) color fitting, visualization on small display, mobile graphics, visual perception.

Full-Color LED lighting system requires efficient control of the lighting color in order to easily achieve various color effects. In this paper, we present not only a portable color scanner using color sensors which can control lighting color directly from detected color but also methods to convert detected color to a complementary color, similar colors and so on. In addition, we propose a compensation method for measured sensor color to reduce measurement errors more than 50[%] in detected color. The developed color scanner is applied to control full-color LED ceiling light for emotional lighting.

As the international competitive landscape deepens, the need to understand foreign cultures and establish effective strategies is increasing. At the beginning of the 20th century, Cartier actively developed exotic designs to secure international competitiveness; theses designs have also been used as design prototypes for Cartier in modern times. The purpose of this study is to analyze the color characteristics and types of exotic designs in the early 20th century, which was a turning point in Cartier's design. After studying the literature, a total of 248 exotic designs were presented in Cartier catalogs. This study also selected overseas monographs from the early 20th century, and their design types were classified and color analysis was performed based on the Natural Color System(NCS). Cartier's exotic designs cover wide range of styles, such as Chinese, Japanese, Persian, Indian and Egyptian styles. Multicolor, primary colors, and contrast are all strongly expressed. 97% of designs contained multiple colors, with at least two colors and maximum of six colors. The most frequently used colors are red, green, and blue, which means that only 9% of the designs do not contain the three colors, showing a high preference for theses three colors. In addition, color combinations of red and green, red and blue, or all three colors are used to show high contrast and utilize complementary colors, or near complementary colors, for coloration. This study is meaningful in that it analyzes the color characteristics of Cartier's exotic designs and translates them into practical data for establishing the color strategies of companies in the global market.

Complementary color filter array (CCFA) is widely used in consumer-level digital video cameras, since it not only has high sensitivity and good signal-to-noise ratio in low-light condition but also is compatible with the interlaced scanning used in broadcast systems. However, the full-color images obtained from CCFA suffer from the color artifacts such as false color and zipper effects. These artifacts can be removed with edge-adaptive demosaicking (ECD) approaches which are generally used in rrimary color filter array (PCFA). Unfortunately, the unique array pattern of CCFA makes it difficult that CCFA adopts ECD approaches. Therefore, to apply ECD approaches suitable for CCFA to demosaicking is one of the major issues to reconstruct the full-color images. In this paper, we propose a new ECD algorithm for CCFA. To estimate an edge direction precisely and enhance the quality of the reconstructed image, a function of spatial variances is used as a weight, and new color conversion matrices are presented for considering various edge directions. Experimental results indicate that the proposed algorithm outperforms the conventional method with respect to both objective and subjective criteria.

The purpose of this study is to identify the color combination characteristic and to find out the characteristics of color tones in interior environments of Korean traditional houses. The results of the interior color combination analysis, it was revealed that contrast was the most dominant in architectural elements color. In the furniture, graduation, contrast and analogous harmony were mainly used. Single color harmony, analogous harmony, complementary harmony were the dominant color combination characteristics in interior accesories. Color tones of architectural elements were dull and light(pale, light grayish, light grayish) and color tones of furniture were dark and dull(dull, dark, dark grayish). However, interior accessories of an-bang show wide range of color tones raging vivid to dark tone, while sarang-bang accessories have tendency to soft, gray and dull tones. Therefore, the color tones of an-bang and sarang-bang elements show clear differences.

The graft copolymer consisting of poly(N-isopropylacrylamide) (PNIPAAm) and single-stranded DNA was prepared. Interestingly, the copolymer was found to form nanoparticles above physiological temperature. We found that non-crosslinking aggregation of the nanoparticles was induced by the hybridization of the surface-bound DNA with the full-match complementary DNA, but not with one-base mismatch. The core material is not restricted to PNIPAAm; DNA-functionalized gold nanoparticle was found to show a similar aggregation induced only by the fully-complementary DNA, resulting in rapid color change within 3 min at ambient temperature. This methodology is general in principle and applicable for wide variety of clinical gene diagnosis.

The aim of this study was to analyze the effect of different sensory information on the motor function which is resulted from visual stimuli. Particularly, it was focused on the effect of complementary color stimuli on reaction time. Twenty volunteers(10 men & 10 women), between the age of 20 and 25 yearn participated in this experiment. Experiments were carried out in a light & sound-attenuated chamber, and the overall system consisted of a PC. interface card. LEDs. key board switch, and display panel. Although many measurements of sensory-motor integration has been studied the quantitative analysis of sensory-motor integration has not been developed well. Quantitative analyses were performed to investigate the effect of the different sensory information on the arm motor system in the point of view sensory-motor integration. The result showed that the reaction time for visual stimuli of complementary colors was faster than that under same color environments : and, in same color environments and the reaction speed was varied inversely with respect to the magnitude of the light wavelength.
