Kim Whan-ki is an unusual instance in Korean modern artists, who payed attention to emotional and expressive effects of colors. The color of Whan-ki's paintings have been recognized as linked with 'blue' in spite that he used colors within the category of 'Colors of Five Directions(五方色)', which are traditional oriental colors composed of red, lue, yellow, white, green and black. Kim Whan-ki unearthed upon similarity of Five Directions Colors to the three(five) primary colors which modern abstract painter like Mondrian layed down. Whan-ki switched the five directions colors to modern ones. Kim Whan-ki's dot painting in which pure and watery color is sucked in ground is modernistic adaptation from ink painting. He packs a dot with sky and earth, moon and stars, forest and tree, birds and flowers, friends at his hometown, wind, sound and so on. Putting tens of thousands of these shapes and colors into a dot is modernistic version from ink painting. In that point there is a possibility to say that 'dark blue' of the dot painting is 'Hyun-saec(玄色)'. Eventually we can make sure that Kim Whan-ki's view of Art originated in oriental philosophy and beauty.

A novel color clustered optical RGB multiple-input multiple-output (MIMO) system is presented. As visible light can be divided into three primary regions of red, green and blue, data can be modulated and transmitted separately using these three color clusters. Each color cluster comprised of 30 RGB LEDs is modulated using on-off-keying (OOK), and selection combining is performed at the receiver, producing a diversity effect within that color cluster. The simulations demonstrate that the proposed RGB MIMO VLC system provides high performance via a relatively simple design of MIMO. Moreover, the proposed system ensures sufficient illumination from LEDs and offers extended distance if more LEDs are applied.

The eyes can register color oscillations and that colors have an effect on the psyche. Human is constantly surrounded by an immense range of vibrations to which he must react and respound. And the skin can be compared to an antenna which amplifies information received from the outside and then passes it on to the inside. Therefore the art of many medicines make use of the skin as a medium of treatment. Peter mandel discovered centers, or zones, on the human body, which represent or correspond to the three primary colors(red, blue and yellow). And he came across to the four temperaments(or humors) and their respective colors, which consist of the primary colors with the addition of green.

Nowadays, many satellites regularly produce digital multispectral images of the earth's surface. Multispectral images may be displayed as color pictures by selecting three components for assignment to the primary colors. It is desired to enhance these images to generate a display picture that are representativde of their features. in this paper, a false color image processing algorithm is proposed for the purpose of enchancement of the multispectral images based on the human perception. The mean of each primary component is transformed to equalo. Intensity and saturation are enhanced by modified piecewise linear contrast strectching and saturation enhancement method. The proposed method has been successfully applied the LANDSAT TM image and shows good enhancement.

The purpose of this study is to examine the relation between the trend of art and fashion which predominate a certain time. In order to achieve this goal, this study intends to analyze how plasticity found in Mondrian's pictures are applied to modern fashion with its focus on formative elements. Mondrian was ahead of abstractionism, a major trend of contemporary art, and defined the theory of neo-plasticism. The theory of neo-plasticism defined by Mondrian is characterized by the limited expression of lines and shapes by using only vertical and horizontal straight lines, and right angles and four-sided figures weaved by the lines, and the use of achromatic color(black, white, and gray) in three primary colors(red, blue, and yellow). Based on his theory, he fully displayed the world of geometric abstraction. Mondrian's formative elements which have been applied in modern fashion can be divided into shape and color, For the element of shape, first, horizontal and vertical lines have been applied to patterns, trimmings, detail, and plane of textiles through simplification of design, representing proportion, balance, and stress in a silhouette, Second, plane and diamond shapes made of horizontal and vertical lines have been applied to textiles or patterns with uniqueness. For the element of color, first, three primary colors and achromatic colors are used to seek the aesthetics of balance and harmony that are produced in the strain of conflict through brightness, chroma, and complementary colors, Second, primary colors of high chroma and brightness which are much stronger than pictures are used to express a modern sense. Formative elements of neo-plasticism, which have been applied to modern fashion suggested by this study, are connected with the trend of art contemporary designers have borrowed, Accordingly, this study will become a very helpful material which provides designers with original ideas in developing materials and patterns which connect design with art.

Dyeing and fastness properties of a dyeable PP fiber were examined with four different types of disperse dyes. It was found that the dyed PP fiber could be cleared by soaping without using sodium hydrosulphite, and that the heat setting above $140^{\circ}C$ resulted in the melting of the PP fiber. The rates of dyeing and the extents of exhaustion of three primary E type dyes were different with each other, the apparent color strength did not increase with increasing dye concentration, and color fastness to washing was not satisfactory. In the cases of both high wash fastness and high light fastness dyes, the rates of dyeing were slow and the extents of exhaustion were very low. On the other hand, the dyeing rates of three primary S type dyes were similar and the build-up properties were good with good color fastnesses. It might be concluded that the best disperse dyes for the dyeable PP fiber were S type dyes.

This paper proposes a vector error diffusion method for smear artifact reduction in the boundary region. This artifact mainly results from a large accumulation of quantization errors. In particular, color bands with a smear artifact, the width of a few pixels appear along the edges. Accordingly, to reduce this artifact, the proposed halftoning process excludes the large accumulated Quantization error by comparing the vector norms and vector angles between the error-corrected vector and eight primary color patches. When the vector norm of the error corrected vector is larger than those of eight primary color patches, the quantization error vector is excluded from the quantization error distribution process. In addition, the quantization error is also excluded when the angle between eight primary color patches and error corrected vector is large. As a result, the proposed method enables a visually pleasing halftone pattern to be generated by all three color separations into account in a device- independent color space and reduces smear artifact in the boundary regions.

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.
