The aim of this study is to provide practical guide for exterior design in apartment and to propose a device to improve the quality of residential environment by the color planning. Color is a language of context and used as a visual aid to recognize the objects and spaces in the world around us. In this sense, each color perception is unique to its own setting and not subject to any universal rules of thumbs, Therefore, when designing with color, each setting will demand its own specific set of rules. A balanced color scheme has to make the environment more pleasant for people to live in . Fro the exterior in housing the use of color has to be considered not just in its wider context of the architecture or surrounding but as an element of the life of the inhabitant. So it is considered on the type of people who will live in and visual condition of site. In this study , the objective model of systematic design process for environmental color planning is proposed on the basis of theroetical background and references investigated, By the existing thesis, resident's preference of the exterior color and foumular of composition in apartment was invastigated . In general theories, based on the theory Birren's color harmony for color coordination an design principles, a device of exterior color design in apartment was suggested by the course of reasonable design process. Color in environment plays many different roles. It integrates the architecture with the site. If color is use well, it can soften architecture that is too harsh, it can give a sense of identity to different part of site and improve a city's image. The environmental color is effective media to enhance the aesthetic value of architecture and environment.

The purposes of this study were to evaluate the color characteristics and color sensibility of mulberry/cotton blended fabrics dyed with indigo, the natural dye, and analyze effects of them on color preferences. The values of CIE $L^*$, $a^*$, $b^*$ $C^*$, h were calculated for the color characteristics of indigo-dyed fabrics, and their hue, value, and chroma were calculated according to the Munsell color system. Fifty male and female college students evaluated the color sensibility of nine types fabrics dyed with indigo on a seven-point scale. The data were analyzed by descriptive statistics, factor analysis, Kruscal-Wallis test, correlation analysis, and regression analysis. The mulberry/cotton blended fabrics naturally dyed with indigo showed the characteristics of PB color tones, low value, and low chroma. The color sensibilities of fabrics dyed with indigo were classified into four factors: 'classic', 'sporty', 'elegant' and 'natural'. There were significant differences according to the fibers and the repeating times of dyeing in the color sensibility for the fabrics. Cotton fabrics were evaluated to be more classic, sporty, elegant, and natural than the mulberry/cotton blended fabrics, and the deeper the color, the more classic, sporty, and elegant the fabric was evaluated. The students preferred the indigo dyed fabrics which have more classic, sporty, and natural sensibility. There were significant relationships between the color sensibilities and colorimetric properties of the fabrics dyed with indigo. The color preferences of the dyed fabrics with indigo were found to be influenced by the 'classic', 'sporty', 'natural' of color sensibility.

Everyone has own color preference and the color preference can affect human psychology in various good or bad ways. Especially patients with chronic diseases often have depressed mood to take pills for their disease treatment. Therefore we evaluate the possibility of their color preference to pharmacotherapy in good way which increases the compliance of pharmacotherapy. We performed this study by a Questionnaire survey for total 150 agreed patients at K University hospital from Aug 7 to Sep 30, 2014. Questionnaire survey was performed to choose color of providing color kit (11 different color range kit) depend on each 16 questions which asked the patient characteristics, health condition, general color preference, color preference for medicine and expectation for drug compliance. In results, most preferred color was blue (20%), whereas disliked color was black (30%) in general life. However, most preferred color for pill was white (32%), for syrup was also white (31%) or orange (28%), and for vitamin was yellow (47%). When we asked the possibility of increasing compliance, if the current taking pill color will be changed for your preference color like a candy bar, 50.4% of respondents marked 4 or 5 of like-scale expressing positive opinion on it. In conclusion, compliance is very important to succeed the treating disease and may apply the psychologic application such as each patient color preference for drug compliance in the future.

When we transformed from Monochrome-data to Color-data in text mode, we used hardware-method to design the circuit which is convertible in real time. We saved color information in every screens that can make screen in Color Palette ROM and it is also generated 8bit. lower 4bit assign foreground color and upper 4bit can design to have background color. We have Address Reduction ROM to remove repeated address and reduce volume of Color Palette ROM to 1/16. Besides, we have many D-FF to save address, data and page information temporarily after that, we have management process 8 times through counter in real time. Finally, we chose either foreground color or background color in multiplex and established color information was sended to the color video controller. Thus, you can use it as a good interface when yow transfer many control devices with Monochrome display (ex, LCD Monitor) into devices with Color display.

A computational color palette extraction model is introduced to describe paint brush objectively and efficiently. In this model, a color palette is defined as a minimum set of colors in which a painting can be displayed within error allowance and extracted by the two step processing of color grouping and major color extraction. The color grouping controls the resolution of colors adaptively and produces a basic color set of given painting images. The final palette is obtained from the basic color set by applying weighted k-means clustering algorithm. The extracted palettes from several famous painters are displayed in a 3-D color space to show the distinctive palette styles using RGB and CIE LAB color models individually. And the two experiments of painter classification and color transform of photographic image has been done to check the performance of the proposed method. The results shows the possibility that the proposed palette model can be a computational color analysis metric to describe the paint brush, and can be a color transform tool for computer graphics.

The representation of color with natural dyes is closely related with the modern well-being life. This study is focused on the representation of target color of the blue, yellow, and red color system, these color sources were originated from the green tea, gardenia, and black rice respectively. The quantitative numerical value of brightness (L), color coordinates (a, b) were designated for the target color, the optimum color nearest to the target value was extracted with the solvent pH, temperature, and extraction time. The longer the extraction time had more thickening color in case of the gardenia. The L-a-b coordinate of extracted color were analyzed with the color difference meter and compared with the target color. The experimental variables were optimized to extract the color of the smallest ${\Delta}E$ with the target color. As a result, the CIE standard value was proposed and the color was represented.

The purpose of present study was to examine how each clothes colors on the basis of 5YR 7/3 face color affect clothes colors images as follows : (1) what general consciousness of clothes colors in, (2) how the impression of the harmony of 5YR 7/3 face color and clothes colors is, (3) when we divide clothes colors according to the property of colors- chromatic color and achromatic color, cool color.neutral color.warm color, in tone, in color colume- if there is the difference of visual evaluation, (4) image analysis of 45 clothes colors with the view of each kind of adjectives. The result of this study is as the following: 1. As a result of the analysis of general consciousness on clothes colors, when subjects chose clothes, they most considered colors and they also considered their face colors. They would choose the color of clothes, which were becoming to their having clothes colors or their face colors when they bought clothes. 2. The impressions of coordination of 5YR 7/3 face color and clothes colors consisted of three dimensions - evaluation, activity and harmony. 3. It was known that as a result of the analysis of visual evalutional differences according to dividing the clothes colors by property of colors, there were such notable differences that they might effect the coordination images of face color and clothes colors differently. 4. After arranging 45 clothes colors on the graphs in 17 adjectives, gethering them thogether in each dimension and as the result of the analysis in the evaluation dimension, estimation of yellow, light green column were low and that of achromatic colors were high. That is, it was known that the evalution dimension was concerned with hue of the color properties. In activity dimension, there were different image according to each adjectives. That is, it was known that the evalution dimension was concerned with hue of the color properties. In activity dimension, there were different image according to each adjectives. That is, it was known that the activity demension was concerned with value and chroma of the color properties. In harmony dimension, achromatic columm was high and yellow, green yellow, vivid green columm were low in harmony. That is, it was known that the harmony demension was concerned with hue of the color properties.

The purpose of this study is investigate the characteristics of color perception among Chinese people, and compare the characteristics among Korean, Chinese and Japanese people, using Munsell color space. The results are as follows: 1) Chinese people were more likely to tell accurately red, yellow red, yellow, purple, and an achromatic color, but did not do accurately green yellow, blue, and purple blue. In terms of a comparison of average perceived color and standard color, there were significant differences among green yellow, blue green, and blue and standard color; 2) Color perceptions of Korean, Chinese and Japanese people were broadly classified into four types. Also, of ten chromatic colors, the color perception type of only two colors, red and yellow, were is same among the groups of the three countries. However, the color perception type of yellow red, green, blue green and blue were different among them; and 3) In terms of a color perception accuracy test among the groups of the three countries, there were not significant differences between yellow and purple and standard color. However, significant differences existed between the rest of the colors and standard color.

PURPOSE. Accurate color matching of maxillofacial prostheses to skin is important for esthetics. A computerized color matching system specific to human skin has recently been developed. The purpose of this study was to evaluate the accuracy in color and translucency matching of the computerized color matching system across different skin colors. MATERIALS AND METHODS. The silicone was colored to simulate 28 different skin colors (n=5) to serve as "target skin colors". Using a spectrocolorometer (e-skin), color codes were determined for "replicate skin color" fabrication. CIELAB Delta-E between target skin color-replicate skin color pairs and translucency parameter were calculated. CIELAB Delta-E values were compared with one-way ANOVA and Tukey multiple-comparison. The agreement between $L^*$, $a^*$, $b^*$ and translucency parameter of target skin colors and replicate skin color were calculated by a two-way mixed average measures intraclass correlation coefficient. Translucency parameter of target skin color- replicate skin color pairs were compared with Paired t-test (${\alpha}=.05$). RESULTS. The mean CIELAB Delta-E value was 3.83 and significant differences were found among colors. The intraclass correlation coefficient showed excellent reliability for $L^*$, $a^*$, $b^*$ and good reliability for translucency parameter (P<.001). The mean translucency parameter of replicate skin colors was significantly higher than that of translucency parameter. CONCLUSION. The computerized color matching system specific to human skin was found to be reliable in terms of color and translucency between target skin colors and replicate skin color.
