The main objective of this research was to understand the characteristics of separation color coordination of contemporary female fashion through the analysis of 'pre-a-porter Collections' of four collections (i. e. cities) - Paris, Milan, New York, London - from the periods of 2004 S/S to 2008/9 A/W. The data collection of 265 was done by reviewing 'pre-a-porter Collections' magazine and total 265 observations were made. Statistical analysis of frequency and also qualitative interpretation of separation color coordination characteristics were completed. The main findings were; (1) In separation color coordination of contemporary women's fashion collections, there were three main types of color scheme which were classified into seven detailed categories of color combination. First was the achromatic color & one chromatic separation color scheme which was classified into four categories of - black & white, black & grey, white & grey, and grey & grey - color combination. Second was the chromatic colors & one achromatic separation color scheme which classified into two categories of achromatic & chromatic color & one achromatic separation color combination, and chromatic colors & one achromatic separation color combination. Third was chromatic colors and one chromatic separation color combination. (2) The achromatic colors and one chromatic separation color scheme showed two phases of reinforcing the strong and modern image, or softening the hard and dull image of achromatic color combination. In color schemes which used more than two chromatic colors, the separation color frequently converted the tedious and monotonous fashion image, which caused by identical or similarity in color or tone harmony, into more attractive and interesting. (3) In conclusion, through the various use and coordination of various color schemes, color harmony and separation colors, the separation color coordination in contemporary female fashion has been suggested the effective way of color combination which can lead the visual pleasure and the vitality along with the unity and the harmony. This characteristics can create various images and visual diversity for fashion. The types and the use of color scheme and separation color showed different trends in four collections.

In this paper, a new technique for color reproduction based on color variation characteristics of digital camera under a dim light condition is proposed. Generally, photographers should adjust a camera exposure properly for obtaining an image with real color tone of subjects. Thus, in case of taking a picture under a dim light condition, the exposure time of a camera has to be relatively longer than the one under a bright light condition. Although images with real color tone of the subject are obtained, the images may get blurred due to the shaky hands of photographer holding the camera. In order to avoid the blur effect, an input image is captured from a camera set as a short exposure time under a dim light condition. Then we propose a method to reproduce color tone of the dim input image. To this end, color variation characteristics which represent color variations of a digital camera are first extracted by analyzing the Macbeth color checker images taken under various exposure values. Then, a color reproduction is performed by an estimation based on the color variation characteristics. Experimental results have shown that the proposed method has achieved better performance of color reproduction, compared with existing methods.

In modem society, fashion is used as a means to express oneself. Colors in fashion are regarded as one of the important design elements and play a significant role. Today men's fashion trend represents to adopt diverse silhouettes, colors and various materials. They can choose diverse color for men's fashion. Brown has been popular colors for both man and woman. It usually represents the image of warm, comfort and classic. This research analyzed Brown whose diverse uses had been observed in fashion and the characteristics of Brown the color combinations in men's fashion through men's fashion collection from 2000 to 2008. The characteristics of color combinations with Brown analyzed two color combinations for the top and bottom as follows: First, the hue characteristics of Brown two color combinations were analyzed in men's fashion. Second, the tone characteristics of Brown two color combinations were analyzed in men's fashion. Third, the characteristics of color combinations were analyzed in the Brown top and bottom according to the hues in men's fashion. The Brown color combinations were analyzed according to the 10 hues and achromatic colors. As a result, 10YR was most used in both the top and bottom in F/W and S/S. As for the Brown color combinations of the 12 tones and achromatic colors in the top and bottom, dark grayish was the most used in S/S and F/W regardless of the seasons. The Brown color combinations in men's fashion were analyzed in terms of characteristics. As a result, 10YR and 2.5Y were most used. They were also of the highest frequency in the color combinations of Brown tops and bottoms.

The epidermal color is one of factors the space for ages. Instead of the epidermal color expression, it made with material and decoration under structure for make shade of meaning before have the new media. But now a days, the epidermal color of the fashion store is getting free owe to the development of color harmony, has a great notion that gets out of the subordinate from color, and it is a emphasized factor with expression and self-control. The epidermal color of the fashion store makes an effort to accept the development and changing of new media. It should show that there role and function is changing constantly according to a new technology, and it gave a motivation for reanalysis about existence and expression of the epidermal color. The purpose of this research is that look around the feature of the epidermal color system, elements, and principle. Then contemporary fashion store is expressive characteristics of epidermal color. Using epidermal color is not common, we can find lots of the case with surface color, layer color, interface color, though. The paper reflects on the meaning and concept of fashion store which enables the application of expressive characteristics on space through advanced technology. Meanwhile, the features of epidermal color such as immateriality of process and communication can be inferred from case analysis.

Most color imaging devices often exhibit color distortions due to the differences in realizable color gamuts and nonlinear characteristics of their components. In order to minimize color differences, it is desirable to apply color correction techniques. Th efirst step of color correction is to select the subset of the color coordinates representing the input color space. Th eselected subset serves as so called color samples to model the color distortion of a given color imaging device. The effectiveness of color correction is determined by the color sampels utilized in the modeling as well as the applied color correction technique. This paper presents a new selection method for color samples based on gentic algorithm. In the proposed method, structure of strings are designed so that the selected color samples fully represent the characteristics of color imaging device and consist of distinct color coordinates. To evaluate the performance of the selected color samples, they ar etuilized for three different color correction experiments. The experimentsal results are comapred with the crresponding results obtianed with the equally spaced color samples.
