A study focused on the implication of the blue and black colors in Korean traditional costume is presented. The presented study shows that the blue color in most of literatures regarding Korean traditional costume implies not only green and blue colors, but also dark blue and black colors. In a broad sense, the blue color implies a color category which includes green, indigo, blue, dark blue and black. On the other hand, the color includes blue, dark blue and black in a narrow sense. The rotor black, however, should not be interpreted as blue and dark blue because it has two bypes of black colors with and without reddish tone. Four reasons that the color blue was understood as the color black were discussed in this paper. The fundamental reason was that the blue color looked like black because of dark shadows. Secondly, there was a difference of color awareness between the color blue in Korea and in China. Thirdly, there was a color difference related to the type of textiles. Finally, other substitutes were used because of the lack of blue dyes.

In order to replance systhetic colors by natural colors as food additive, properties of Gardenia yellow color and Gardenia blue color were compared with Food yellow No. 4 and Food blue No. 1. Color differeance between Food yellow No. 4 and Gardenia yellow color was 7.55. Thermal stability of Food yellow No. 4 was above 99%. On the other hand, in case of Gardenia yellow color, showed adove 90% of residual color units in 8$0^{\circ}C$$\times$30min and 10$0^{\circ}C$$\times$30min at pH 7.0 but 75% in 121$^{\circ}C$$\times$15min. Difference of light stability between Food yellow No. 4 and gardenia yellow color was about 18%. Addition of ascorbic acid was increased about 6% in light stability. Color difference between Food blue No. 2 and Gardenia blue color was 107. Thermal stability of Food blue No. 2 was above 99%. But Gardenia blue color showed 92% of residual color units in 8$0^{\circ}C$$\times$30min and 10$0^{\circ}C$$\times$30min at pH 7.0 but 90% in 121$^{\circ}C$$\times$15min. Difference of light stability between Food blue No. 4 and Gardenia blue color was about 8%. Addition of -tocopherol was increased about 4% in light stability of Gardenia blue color.

The purpose of this study was to investigate the characteristics of traditional blue color between Korean and Japanese traditional costumes. Korea and Japan as the neighboring country of geographically and historically, but showed obvious difference in traditional color. In this study we investigated the blue color characteristics that appear on Korean and Japanese traditional costumes. We researched the characteristics of blue color on color names and color tones through the old Korean and Japanese literatures, costume remains and restoration dyeing fabrics. This study researched the Chosun Period in Korea and Edo Period in Japan. The results of this study Were as following; Many differentiation colors appeared in Chosun and Edo period than former ages. These differentiation colors were made giving differences gradually in basic color, hue, value and chroma. The blue color names appeared 40 names in Chosun Period and 57 names in Edo Period. In these blue color names of Chosun and Edo Period, the common color name was not more 'indigo'. The most highly appearanced blue color hues of costume remains in Chosun and restoration dyeing fabrics in Edo Period were blue and purplish blue. The most highly appearanced blue color tones were dull and moderate. By result of preceding descriptions, the characteristics of national color were not come from difference of dye and dyeing method, could know that come from difference of society and cultural environment.

The confucianism, the Taoism, the Budd-hism and the Folk-Faith actually coexisted and all of them had also widespread infuluence on the Chosun Society. This thesis is designed to study symbol of Color Scheme expressed in the clothing of Chosun dynasty. For this thesis I examined records of Royal archives, books containing lifestyle of Chosun dynasty, genre paintings, documantary pain-tings, excorcist clothing and existing remains. And I synthetically studied symbol of the Clothing Color Schemes in Chosun dynasty on the bases of theoretical researches. The result were as follows. There were many cases of 1. Upper·lowergarments : Red-Blue, White-Blue, White-Blue Color Schemes. 3. Exorcist clothing : Red-Red, Blue-Yellow, Blue-Blue Color Schemes. 4. Multy-colored stripes : Same color arrange-ments were avoided in Color Schemes. In the case of Green Wonsam, Blue-Red-Yellow-White Clothing Color Scheme was obvious. 5. Dance wear : Red-Blue, Yellow-Red Color Schemes. Generally more than anything else Blue-red Clothing Color Scheme was widely used. Be-sides Blue-Red Color Scheme, there were also many cases of Red-Yellow, White-Blue Cloth-ing Color Schemes. As a whole, compatible Color Schemes were more often used than in-compatible Color Schemes were used with various symbols that were based on color concept of Yin-Yang O-haeng, Tae-il theory Folk-Faith and so forth in Chosun dynasty.

This study was conducted to investigate the dietary and nutritional status supplied by group feeding for blue color and white color in Seoul and Kyunggi area. The results are summarized as follows : 1. Blue color and white color of the average food supply per person per day was 1370.0g. Blue color of the total fool supply was consisted of 35.1% grain, 44.1% vegetables. White color of the total fool supply was consisted of 31.8% grain, 44.0% vegetable. The amount of milk product, fruit and fat supply were very small. 2. Blue color and white color of the ratio of main dish and side dish supplied was 69 : 31, 60.0 : 39.7. 3. Main dish all is rice. Side dish ard kinds of soupes and Jigeai Johngol in the two groups. In the kind of side dish white color much more than blue color. Dessert are scarcely supplied in the two groups. 4. The mean daily supplies of energy and 9 nutrients were above the level of the R.D.A. Blue color and white color of the mean daily amount of energy supply was 2653.0㎉ 3022.6㎉. Blue color and white color of the ratio of carbohydrate, protein, and fat supplied was 68.4%, 18.6%, 13.1%, and 62.1%, 20.9%, 17.0%. 5. Blue color and white color of the average feeding cost amounts to 460won, 812won per meal. 6. Blue color; There were high correlations in supply amoung energy, protein, fat. Carbohydrate, calcium, iron, riboflavin, niacin. White color; There were high correlation in supply amoung energy, protein, carbohydrate, calcium, iron, thiamin, riboflavin, niacin, vit-C.

This study's goal is to analyze the color characteristics of Blue used in men's fashion for design developing process. First, we researched the previous studies and examined documents about color characteristics of Blue in general as well as coloration in fashion design and men's fashion. We composed color samples by collecting two-color coloration used in men's fashion collection for 5 years from 2004 S/S to 2008 F/W through a specialized fashion information web-sites. We limited the colors from Blue Green(BG) to Purple Blue(PB). Second, we analyzed the characteristics of hue combination and tone combination. A total of 351 pictures were collected and RGB and HV/C value were converted with Munsell Conversion program(ver.8.0.1). Color data has been sorted to 10 hues and 12 PCCS tones. From this, we were able to figure out that similar/same hue coloration was used more than contrary hue coloration and similar/same tone coloration was used more than contrary tone coloration for Blue. We've limited Blue coloration characteristics of men's fashion to two-color coloration for an analysis; the succeeding study will need to examine on the characteristics of multi-coloration and detailed Blue coloration image by various garments.

With the progress of the aging society into the aged society, the planning of senior housing is inevitably required. Among the factors of planning, color appeals to people's vision which mostly accepts information about the environment, so age-related color vision changes should be studied. The purpose of the study is to find out characteristics of color perception focused on yellow and blue with advancing of the yellowed eye sight in the old age. The findings are as follows. (1) Regardless of gender, losses of color perception in sensitivity is occurred as aging is proceeded. But the rate of reduction is mitigated compared with the ex-research in Japan because of the promotion of physical health. (2) Human lens coloration was not common until 85 years old and the hue of yellow and red was easily perceived by the older subjects. (3) Yellow is more preferred to other colors by the elderly and accuracy of yellow-color perception is higher than that of blue-color. (4) It is especially hard for the elderly to perceive the difference between pure blue and mixture of blue-green. Therefore blue and blue-green should not be adopted simultaneously in senior housing environment. Except for the space which specially requires carefulness, various color preferred by the elderly should be applied to the senior housing environment to satisfy their psychological condition and provide the vitality of life.

The colors of a tinted lens for a mixed color could be applied to a subtractive mixture's law, and the estimation of a tinted lens used the properties of optical absorptions and the color analysis. The optical absorption properties of Yellow(x)-Blue(1-x) depended on the yellow color in short wavelength below 500 nm, the absorption in the 550~650 nm wavelength regions depended on the blue color. The absorption band in the 550~650 nm wavelength regions was a peak for an ion of transition metal. The color properties of Yellow(x)-Blue(1-x) analysing by the $L^*a^*b^*$ of CIE system shifted to toward $+a^*$ decreasing x, it was formed of a pure color because of a low saturation existing in +0.6.
