The purpose of this study is to suggest the prediction model for the color design by the image types in the office interior. This prediction model of the color design is for the more comfortable environment by using suitable, various colors fitted with business functions. In this research, we carried out the evaluation experiment with the variables such as the color on ceiling, wall, floor and the harmonies of color schemes. We set the prediction index through the multi-regression analysis. And the prediction model was made by these results. The design methods by the prediction model are as follows. 1) The $\ulcorner$variable$\lrcorner$ image was deeply influenced by the value and chroma and it was marked high in low value and high chroma and the harmonies of contrast and different color. 2) The $\ulcorner$comfortable$\lrcorner$ image was related to the value and chroma and it was marked high in high value and low chroma and harmonies of homogeneity and similar. 3) The $\ulcorner$warm$\lrcorner$ image was greatly influenced by the hue and the harmony of color schemes, and it was marked high in the warm colors and harmonies of homogeneity.

The purpose of this study was to check color change depending on dyeing conditions when silk fabrics was dyed with gromwell and to investigate mordant effect when synthetic tannin was used as a mordant. First, when silk fabrics were dyed with gromwell, the change of color, brightness and chroma were examined by measuring K/S value, a, b value, L value and C value depending on dyeing condition. Second, color, brightness and chroma differences which appeared after mordanting with synthetic tannin were investigated and muti-functional mordanting effect was confirmed with dyeing fastness, antibiosis. As a result of color analysis of gromwell, it was proved that the main pigment of gromwell was shikonin. Color was red purple at pH 3 when silk fabrics were dyed with gromwell. But It became greenish and bluish as temperature rose and time passed by. And it grew reddish and yellowish as concentration level reached higher. The color became purple at pH 5 and purple blue at pH 7. Both at pH 5 and pH 7, it became greenish and yellowish, as temperature went up and time ran by. And it became reddish with concentration increasing. Brightness and chroma decreased with temperature and concentration increasing as well as time passing by. After mordanting with synthetic tannin, the color became less reddish at pH 3 and reddish-yellowish at pH 5 and pH 7. The brightness increased and the chroma decreased. At all pH, the color, the brightness and the chroma became similarly by synthetic tannin mordanting. Dyeing fastness of synthetic tannin mordanted fabric was higher than that of non-mordanted fabric. Especially, wet fastness at pH 3 improved from 1 grade before synthetic tannin mordanting to $3{\sim}4$ grade after tannin mordanting. Antibiosis was improved by gromwell dyeing and synthetic tannin mordanting.

색은 인간에게 어떤 느낌을 전달하기도 하고 행동에 영향을 미치기도 한다. 특히 적절히 적용된 색은 제품의 품질과 사용성을 향상시키기 때문에 색의 효과에 대한 이해와 신중한 사용이 중요하다. 그러므로 본 연구에서는 온도감에 대한 색의 3요소(색상, 명도, 채도)의 효과와 그 관계를 정확히 이해하고 정보 디스플레이에 적용할 수 있는 응용적 가치를 탐색하고자 하였다. 색상환에 따른 10가지 색상의 온도감은 U 모양으로 나타났는데 빨강에서 가장 높고 파랑과 남색에서 가장 낮았으며, 채도는 색상이 가지는 온도감의 특징을 더 두드러지게 한 반면, 명도의 효과는 없었다. 이 결과는 색의 사용에 제한이 있는 상황에서도 채도의 다른 요소를 조절함으로써 온도감에 변화를 줄 수 있음을 보여준다. 한색과 난색의 구분은 명확하였으며 이러한 색의 주관적 온도감 차이로 인해 참가자들은 그래프 판독에서 실제의 온도보다 더 따뜻하거나 더 차갑다고 보고하는 온도계 측정에서의 판단 왜곡을 보였다. 이런 차이는 과제와 디스플레이 특성에 맞게 색의 구성요소들의 민감도를 조절하는데 적용할 수 있을 것이다.

This paper presents a composite luminance signal processing system for NTSC, PAL and SECAM standards. Eaxh of the three standards employs its own specifications of subcarmier bandwidth and luminance signal waveform. The proposed system, compatible to the specifications of the three standard and B/W TV, implements variable freqneucy characteristics by controlling filter coefficients. The major features of the system are a luminance/chroma separation unit and an aperture compensation unit. The luminance/chroma separation unit employes a notch filter selection a trap freqneyc to atenuate unwanted color signals in luminance signal bands. The aperture compensation unit comprises two subunits, to provide clear color definition for each of the three standards: a primary compensation circuit and a variable compensation circuits. The proposed system yields a 40 dB gain from the chroma/luminance separation and a 10 dB gain from the aperture compensation unit.

There are many discrepancies between visually perceived color-difference and that which is quantified from an instrumental measurement when dark color samples are measured in the textile industry. The samples were prepared to represent these dark shades and the values of the instrumental results from conventional color-difference formulae(CIELAB, CMC, BFD II, CIE94, LCD99 and CIEDE2000). Those of visual assessment were compared. The experimental results show that the CIELAB formula gives the best performance over other formulae, and the CIEDE2000 formula for the color-difference according to chroma presents the worst performance. Therefore, we can say that the problems in color matching of dark shades are caused by imperfect formula, because the results obtained from a color-difference formulae are different and the CMC which is used as a standard color-difference formula in the textile industry is not correct. So, a revised color-difference formula is proposed in this study, to account for these problems.

The purpose of this study is to ascertain the color design element in traditional palaces among those in the neighboring three nations of East Asia, notably Korea, China and Japan. Undoubtedly the ultimate goal to be pursued, by so doing, has to be inquiry into the identical prototype of Korean color design element. The East Asian color palette is rich in symbolic meaning, mostly these color are in harmony with the nature and human life. In this study, the color of the traditional palace is characterized by the actual color use. The colors of China are various, but they concentration R～G, middle/high level of chroma. In Korea, the colors in palace are distributed in YR/GY, middle/low chroma, relatively higher value. While the major features of Japan color are YR/achromatic with middle/low levels of value and chroma.

This purpose of present study was to examine the figures and colors of hanbok textile. The data were collected from 489 pieces selling at hanbok shops in Taegu pusan and were analysed. Result of this study was as follows: 1) Figures As the hanbok figures tradition figures were used a great many among the figures. The next was natural geometric abstract figures. The reactionism trend was worthy of notice in figures and traditional design occupied most of them. 2) Color In the hue, YR, R, RP group were used concentratedly. Because 5,6,7 level were used a great many among the value value was represented lightly more than midium light. Because 2,3,4 level were used a great many among the chroma chroma was represented duller than midium chroma. Thus hanbok color was used mainly in a several party and korean were tendancy to like natural the sence of color.

A purpose of this study is to 6nd out how the casual and formal style clothes of stripe pattern giving variety by pattern direction, pattern width, and contrast coloration have an effect on image of wearers. For this, 192 stimuli were made and 1200 testee evaluated them using semantic differential scale. As a result, five image dimensions were drawn as a factor of attractiveness, gracefulness, activeness, visibility, and tenderness. Unlike the value contrast previously researched, it showed that chroma contrast coloration which was interacted with a color tone contrast coloration had an effect on all the 5 image dimensions. This result was recognized as significant clothes dues in evaluating the image of stripe wearers. Besides, clothing style, stripe pattern, and contrast coloration were made clear as an efficient parameter in image presentation of clothing wearers.
