This study is to examine personal color - preferred color, well-matched color and the relations between preferred color and the well-matched color. Focus is also placed on how sexual difference influences color temperature preference. For data collection, a questionnaire including color stimulus was employed. The subjects of this study were the male and female college students who lived in Pusan. The results of the research are summarized as the following : In view of preferred color, male subjects preferred KEY2 color(warm) in red, pink, and yellow, and preferred KEY1(cool) in green and blue. While most subjects showed the same signal, in green, male preferred KEY1 color and female preferred KEY2 color. Concerning preferred personal color type, KEY1 type person liked KEY1 color except red, and KEY2 type person liked KEY2 color except blue. This shows that people prefer the focused color presenting its own traits. In view of well-matched color, most subjects liked KEY2 color in red, yellow, pink, and they selected KEY1 color in blue as the well-matched color. However, in green, each sex showed different preferences; while male subjects selected KEY1 color as the well-matched color, female ones selected KEY2 color. In each personal color type, KEY1 type male evaluated KEY1 color as the well-matched color, KEY2 type male evaluated KEY2 color except blue. KEY1 type female chose all the KEY1 color as well-matched colors, and KEY2 type female chose KEY2 color. The well-matched colors are similar between male and female subjects. In over 80 percentage of the answers, the preferred colors coincided with well-matched colors. KEY1 type persons chose KEY1 color, and KEY2 type person chose KEY2 color as the well-matched color. These results show that there is a meaningful relationship between the preferred color and well-matched color.

The most popular technique for image retrieval in a heterogeneous collection of color images is the comparison of images based on their color histogram. The color histogram describes the distribution of colors in the color space of a color image. In the most image retrieval systems, the color histogram is used to compute similarities between the query image and all the images in a database. But, small changes in the resolution, scaling, and illumination may cause important modifications of the color histogram, and so two color images may be considered to be very different from each other even though they have completely related semantics. A new method of color feature representation based on the 3-dimensional RGB color map is proposed to improve the defects of the color histogram. The proposed method is based on the three 2-dimensional projection map evaluated by projecting the RGB color space on the RG, GB, and BR surfaces. The experimental results reveal that the proposed is less sensitive to small changes in the scene and that achieve higher retrieval performances than the traditional color histogram.

Color shade variation was investigated in zirconia dental blocks, prepared using commercial powders. As a reference color-shade block we used the color indexes of A2, A3.5, A4 and B3, according to the VITA classical color scale. The zirconia powders for color shade blocks showed colors of white, yellow, pink and grey, respectively, after firing at $1530^{\circ}C$. The zirconia powders were mixed according to the recipe of color shade blocks and shaped at lower pressure using a uniaxial hydrostatic press. The shaped sample was inserted into a vinyl pack and sealed in a vacuum form machine. The shaped block samples were reshaped at 450 bar using an isostatic cold press and fired at $1530^{\circ}C$ for three hours. In order to investigate the atmospheric color variation with firing temperature, the A2, A3.5, A4 and B3 sintered blocks were fired between $700^{\circ}C$ and $1300^{\circ}C$ under controlled atmosphere of $pN_2$ and $pO_2$. The surface color picture was taken using a smart phone camera and compared with the results obtained using the VITA classical color scale. Quantitative color index value, CIELAB, was measured using a color-meter. Above $800^{\circ}C$, the color darkness greatly increased with the increase of the reduction temperature and keeping time.

가상 환경에서는 3차원 작업 공간과 3차원 인터랙션이 가능하나, 대부분의 가상현실 애플리케이션은 2차원의 색상 선택기를 사용하고 있다. 본 논문은 가상 환경에서 3차원 색 공간에 기반한 3차원 색상 선택기를 구현하고, 기존 2차원 색상 선택기와 색상 선택 성능을 비교하였다. 3차원 색상 선택기는 3차원 색 공간을 그대로 사용하여 직관적이며, 가상현실 장비인 컨트롤러를 사용하여 색 공간의 특정 지점에 3차원 포인터를 위치시킬 수 있기 때문에, 간단한 사용자 작업으로 색상을 선택할 수 있다. 이에 비해 2차원 색상 선택기는 컴퓨터 환경에서 색상을 다루는 작업을 하는 기존 사용자들에게 익숙하다는 장점이 있으나, 2차원 인터페이스로 색의 속성을 설정해야 하므로 여러 단계의 사용자 작업이 요구되는 단점이 있다. 사용자 실험을 토대로, 가상 환경에서 2차원 색상 선택기 외에 3차원 색상 선택기의 유용성을 확인하였으며, 3차원 색상 선택기를 활용하여 가상 환경에서 자연스러운 3차원 작업을 할 수 있었다.

This study aims to investigate the color characteristics of female fitnesswear by analyzing the status of color usage and color arrangement method of each item of female fitnesswear of sports brands. This study targeted eight global total sportswear brands. A total of 2956 colors of female sportswear were collected and analyzed from the homepage of each brand. As a result of analyzing the color of fitnesswear, first, the overall color of the fitnesswear showed high distribution centered on PB, Bk and R of low color tone, such as p and dkg. Moreover, bright tone colors were added for vitality and functional image of sports. Second, as a result of analyzing the color of each item, commonly, the PB, Bk and R had large proportions. Third, as a result of analyzing 2-color arrangements of fitnesswear, color arrangements including achromatic color had overwhelmingly higher frequency than color arrangements that had only chromatic colors. This shows that the color arrangement using achromatic color is important and has a higher preference. Fourth, as a result of extracting the representative color arrangement as color chip and comparing, the 2-color arrangement of female fitnesswear had the characteristics of the color arrangement of large area main color and small amounts of emphasized color centered on achromatic colors of Bk and W. This study is meaningful that it can be utilized as basic data for color planning of fitnesswear brands by subdividing female fitnesswear into 4 items and analyzing the color-tone and arrangement.

The purpose of this study is to investigate the absorbance of the Shikonin, one of the major purple pigments, and the stability against the effect of light, $O_2$, and temperature. The effect of mordant and mordanting condition to color and color-fastness is compared and analysed through the color-fastness-test, color-difference value-test, and IR-test. The results were as follows; 1. The absorbance of Shikonin was examinated through 6 kinds of solutions and distilled water. Shikonin was absorbed by solutions rather easily than distilled water. 2. The light effect to Shikonin indicated that the solution with the light was more stable than that without it. 3. The effect of $O_2$ to Shikonin showed that the solution with the $O_2$ was more stable that without it $O_2$. 4. Shikonin -methyl alcohol solution was stable in $25^{\circ}C$. It was unstable in $60^{\circ}C$ and $100^{\circ}C$ with lowered absorbance and changed colors. 5. Color-fastness test to silk and cotton indicated washing color-fastness and perspiration color-fastness was more than 3 grade. But the light color-fastness and crocking color-fastness was low. 6. The comparison between non -colored sample and colored-sample showed the latter was better in fastness. 7. Mordant as $Alk(SO_4)_2{\cdot}24H_2O$ and $AlCl_3{\cdot}6H_2O$ was better than anything else in fastness. 8. Color-difference value-test indicated that the mordant which had the jade green color, the original purple pigment color, was the best in use. 9. The best way to extract the original purple pigment color was in $25^{\circ}C$, because extracted dyeing solution by Soxhlet had the bluish color.
