  • Color plan that contains corporate color of Seoul apartment has a great influence on city environment, considering high-rise vertical dispersion and extent. Therefore, it is necessary to view color plan from an integrative viewpoint. Here, this research aimed at deriving guideline factors of esthetic color plan based on city identity, by recognizing the importance of apartment color and color plan characteristic of recently built brand apartments. Exterior color plan characteristic of Seoul brand apartments seen in this research, first, most of dominance colors were in same color similar tone with warm color in bright and warm image, as the psychological function, accessory colors appeared in similar tone of similar color harmonious with the dominance color. Also, accent color was highlighted with its identity through cooperative color. Second, emotional effect diminished size and weight of high-rise apartment. The upper levels showed clear and clean image, middle to lower level showed stability and comfortable image, on the whole, refined and urbane image that aim for natural and modern image. Therefore, apartment color plan requires, first, in respect of dominance color, unity is required proper for urban image by preparing color permission limitation standard. Second, dominance color and accessory color require historicity and differentiation in sociality that urban identity gets. Third, high-rise upper level cooperative color accent color requires compatibility with urban landscape. Lastly, guideline along with rate is required for color, tone, and pattern, etc. by extent contrast. Here, apartment color plan requires consistent research as urban environment color, also, base study should be accelerated as a part of competitive city branding.

  • This paper describes a new algorithm for pixel-based skin color detection to differentiate human form in color images by the ratio of R to H. In order to detect skin color efficiently, we examine the distribution of the R, G and B color elements combining to constitute the skin color in various color images. It shows that R is located in a narrower area than G and B on the RGB color space. And skin color is more related to R than G and B. Meanwhile, when the color image is transformed to the HSI color space, the S is variously changed in accordance with skin colors. The I is changed in accordance with the quantity and angle of light. But the H is less influenced by other conditions except for color. On the basis of the aforementioned study, we propose that the threshold for skin color detection is decided by the ratio of R to H. The proposed method narrows down the range of threshold, detects more skin color and reduces mis-detection of skin color in comparison to detection by R or H. In experimentation. it shows that the proposed algorithm overcomes changes of brightness and color to detect skin color in color images.

  • 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.

  • The purpose of this study is to find out the effect of suit color, necktie color and necktie patterns on the men's suit image formation. The experimental materials developed for this study were a set of stimuli and response scales. The stimuli were 28 color pictures manipulated with suit color, necktie color and necktie patterns by computer drawing. The experimental design consists of 3 factorial design; 1) suit color (navy blue, beige), 2) necktie color (analogous, complimentary color), 3) necktie patterns (plain, dot, stripe, check, paisley, floral, abstract) The 7-point semantic differential response scale designed for visual evaluation of men's suit image on suit color, necktie color and necktie patterns were composed of 34 bipolar adjectives. The subject are 150 female undergraduate students in Chin-ju city. They responded twice to 14 stimuli at random order The result of this study are as follows; 1. By analyzing the responses of the subjects, 4 factors emerged in the dimensional structure of the men's suit image formed by suit color, necktie color and necktie patterns. The 4 factors are charm, potency, uniqueness and tenderness. Among these, charming and potential factors proved to be more important. 2. necktie color, suit color and neckite patterns had the significant effect on the formation of men's suit image. In the charm image, only necktie patterns were proved to be the most dominant variable. The most dominant variable in the potencial and unique image was necktie color and second to it suit color was important. But suit color was most significant in the image of tenderness. 3. In the effects of interactions between each variables, the combination of suit color and necktie color wins more significant than that of suit color and necktie patterns and that of necktie color and necktie patterns, but in the image of tenderness, only the combination of suit color and necktie color was more significant. In the interaction of suit color, necktie color and necktie patterns, the potential factor didn't have the significant effect.

  • The purpose of this study is to analyze the image of color combination in fashion design. For this study 14,121 color samples were collected from 116 fashion brands selected by the market segmentation based on the results of the previous studies. The brands have high market share and brand recognition in each segmental market. The color samples were measured by spectrophotometer and analyzed by the Munsell's H V/C and CIE $L^*a^*b^*$ value. The representative colors of each market were selected concerning the tensity in CIE $L^*a^*b^*$ color space and the distance between the color samples. h4 a result, 2,213 representative colors were chosen. These color samples composed top and bottom color combination samples by the program 'Item Comparator' that calculated the color differences$({\Delta}E^*)$. Top includes the items such as blouse, shirt, and coats, bottom includes the items such as skirt and pants. The color combination samples were divided into two groups. In one group ${\Delta}E^*$ was less than 30, and In the other group ${\Delta}E^*$ was 30 or more. For investigating the image of color combination, 480 rotor combination samples were classified. The image adjectives for the survey from preceding studies and brand dictionaries were 'classic', 'modern', 'feminine', 'casual', and 'romantic', which have highly preferred in women's wear brands. The result of the study is as follows; For 'classic' 'image, YR, and greyish tone were generally preferred. In the color combination of 'casual' image, the samples with PB color and greyish tone were preferred. For 'feminine' image, RP was preferred as a top color, R, RP, P were preferred as a bottom color. For 'casual' image, PB was preferred as a top color, PB, B were preferred as a bottom color. For 'romantic' image, RP was preferred as a top color, R, P were preferred as a bottom color. The bigger the color differences between the color combination samples were, the more remarkable the image of color combination samples was.

  • The purpose of this study is to fond out the characteristics of color perception and preferred color scheme of the aged who becomes color weak due to yellowed eye sight. For this, this study was composed of two steps. First, an experimental simulation on aged vision using Spectrophotometer(CM-2600d, Minolta) attached Y-2 filter as a quasi lenses of the aged eye. The color data of 120 color chips of the aged vision was measured and analyzed to grasp the characteristics of color perception of the age. Then, a questionnaire survey was carried out with color chips and 8 interior color schemes. They participated in a questionnaire survey of the level of identification among the color chips of 11 tones of R, G, PB, as well as a survey of the preference color schemes. The result of this study are as follow; 1) The range of color perception on hue narrowed into YR, Y, GY, G. Especially, the aged have failed perception of B${\cdot}$PB${\cdot}$P${\cdot}$RP(short wave length of light) by yellowed eye sight. 2) The level of identification among the color chips of 11 tones of R,G,PB are different by each color. But Very Pale, Pale, Strong, Vivid are fractionated similarly in almost color. 3) In the preference of interior color scheme of the aged, preference color harmony scheme Is the complementary color scheme that is easy for identification, rather than analogous color scheme. The preferred dominant color is warm color rather than cool color.

  • The purpose of this study was to analyse the previous color studies. A number of publications and journals were reviewed and analyzed carefully. The results of review and analysis were as follows : There were many different subjects in color studies and they were usually categorized into ten fundamental groups : color preferences, color image/symbol/association of ideas, emotion and colors, image making with colors, colors related with consumers' decision making, traditional colors, semantic color description, color plan of apparel merchandise, influential factors on colors, and color coordination preferences. In general, the color preference studies are conducted most actively, and they are followed by the studies of color image/symbol/association of ideas and traditional colors. In the previous studies on the color preferences, they provided sufficient amount of information on the preferred colors and the preferred apparel colors. however, they lacked in providing appropriate explanation on how these color preferences were related with colors in fashion. Also, there have been no thorough studies that questioned the reliability of measurement methods for obtaining color preference data. The authors also realized that it was extremely difficult to find any related publications on the studies that focus various influential variables on the disagreement between the preferred color and preferred apparel color. Thus, this study directed the future studies to solve the problem discussed above.

  • The digital space color of new media environment denied not only the deterministic relationship of designed color and circumjacent color but also the deduced an special elements of digital space color. Such phenomena historical perspective of Gernot Wersig, new media principle of Lev Manovich and remediation of Bolter, J.K & Grusin, R. are expressed in various new media environment across. In particular, development of digital technology is moving away from its previous space color based on scientific, statistical and quantitative perspective by using diverse variables. The following research focuses on the fundamental concept of space color by type, composition of digital space color. The paper reflects on the meaning and concept of contemporary which enables the application of digital space color system on space through advanced technology. The principle of digital space color such as multidimensional malerisch, discontinuous video, vague original and copy, irregular repetitiveness of 'copy of copy', selective color of observer, experiential color of observer, and etc. makes it possible to extract the expressed element and method of digital space color. Meanwhile, the features of digital space color such as divided field of form, non-systematized of process and collage of communication can be inferred from case analysis.
