  • The purpose of this study was to examine the visual evaluation of image according to the style, hue, value, and chroma of the male clothing and the preference of image. A quasi-experimental method was used for this study. The first factorial design was the $2{\times}3{\times}2{\times}2$ (style of upper clothes ${\times}$ hue ${\times}$ chroma ${\times}$ color of trousers), and the second factorial design was the $2{\times}3{\times}2$ (style of upper clothes ${\times}$ value ${\times}$ color of trousers). The styles of upper clothes were a soutien collar casual jacket and a polo shirt. The subjects were 509 female college students living in Seoul. Factor analysis showed five image categories of men's clothing: initiative, dignity, politeness, activity, and mildness. Yellow was evaluated as having the highest initiative and activity. Blue was shown to have lower mildness than red and yellow. The high saturated chroma was perceived to be higher initiative and activity than low chroma. The shirts were evaluated higher in activity and mildness than the casual jackets were. The beige pants were perceived to be higher in dignity and mildness than the dark blue pants. The high chroma jackets were perceived to be higher in both initiative and activity than the low chroma jackets. The navy blue pants with the upper clothes in low chroma blue were perceived to be higher in politeness than with the upper clothes in low chroma red or yellow. The low value clothes were perceived to be higher in both initiative and dignity.

  • Natural red colorants were extracted from Phytolacca americana Linne by using 50% ethanol solution at room temperature for 12 hours. The colorant components were partially purified as yellow and deep red colorants by thin layer chromatography. Natural red colorants were consisted of major water-soluble red colorant, having maximum absorbance at 538nm and alcohol-soluble yellow colorant, having maximum absorbance at 664nm. Concentration of red colorants were calibrated by the equation of dye(mg/ml) $A_{538nm}\times{1.284}$. Red colorants were changed to yellow at extreme alkali pH and repaired 55% color intensity by neutralization of pH and stabled below $55^\circ{C}$. Dyeability of red colorants against wool fabrics was mainly operated by red pigment having 538nm absorbance without big color differences. Below $55^\circ{C}$, color differences $(\Delta{E}^*_{ab})$ were not changed in spite of big difference of chroma$(c^*)$, having higher scores at higher temperature. The effect of mordants were not drastically changed parameters of color difference without copper ion. Citric acid was big changes of color difference$(\Delta{E}^*_{ab})$ in spite of similar chroma$(c^*)$ values. From these experimental results, red colorants from Phytolacca americana Linne is available for wool fabric dyeing.

  • The purpose of this research was to investigate the effects of clothing style and color of male casual wear on image perceptions and age evaluations. $4{\times}2$ (top color${\times}$trouser color) and $2{\times}3{\times}2$ (clothing style${\times}$clothing hue${\times}$clothing chroma) factorial designs were used as the experiment designs. Photoshop program was used to manipulate the clothing colors after creating photos of models wearing experiment clothing for stimulus. Subjects were 280 female college students from Seoul region and each subject responded to two stimuli. Factor analysis showed four factors of images of male casual wear; sociability, conspicuousness, softness and masculinity. Polo shirts were evaluated higher in sociability and softness than jumpers and nary blue trousers were evaluated higher in masculinity than beige trousers. High chroma clothing was assessed higher in sociability and conspicuousness than low chroma clothing. High chroma red jumpers displayed very sociable feel and low chroma blue jumpers displayed the lowest sociability. High chroma male clothing resulted in younger age perception but age was evaluated young when a black shirt was worn under the jacket when wearing a low chroma jacket.

  • 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.

  • Objective: The objective of this study is to evaluate affection on how users perceive colors viewed from an automotive visual display according to cultural and radical differences including North America, Europe, and Southeast Asia. This study especially aims to identify effects of the variation of tone and chroma of representative color groups by analyzing affection differences depending on cultural and racial differences targeting the colors constituted through variation of tone and chroma, centered on representative colors. Background: The colors of the menu, information display or background viewed through an automotive visual display are an important factor stimulating consumer's affection, and therefore an effort to express the vehicle's brand and product image through colors is made. The studies on colors focus only on the research on unique characteristics of colors, but an affective approach lacks according to cultural and racial differences on colors considering tone and chroma variation within a color from the currently used automotive visual displays. Method: To grasp the visual affection felt by users, this study extracted affective adjectives related with colors through existing literature and a dictionary for adjectives, and presented human affection dimensions on colors through evaluation of various colors. Prior to carrying out affection evaluation, the basic light sources, red (R), green (G), and blue (B) constituting the colors used for automotive visual displays were defined as a representative color group, respectively. When colors in a color group are constituted, the evaluation target of each color group consisted of the colors considering the variation of tone and chroma by changing color sense through RGB values of the remaining two light sources. And then, this study carried out affection evaluation on the constituted colors targeting the subjects with cultural and racial differences. Results: As a result of evaluating the constituted colors with representative affections, there were statistically significant differences between the groups having cultural and racial differences. As a result of S-N-K post-hoc analysis on the colors showing significant differences, North America and Europe were classified as heterogeneous groups. In some cases, Korea was classified as the homogeneous group with North America, but Korea was mainly classified as the homogenous group with Europe. Conclusion: The representative affections on colors from an automotive visual display was drawn as three affective dimensions: passionate, neat, and masculine. Based on these, the affection of Korea and Europe on the constituted colors showed significant differences from that of North America, as a result of affection evaluation on the constituted colors viewed through the visual display by reflecting cultural and racial factors. Regarding representative color groups, bigger cultural and racial differences were revealed in terms of affection on red and green colors than on blue color, and variation of affection was the biggest in the red color. Application: This study analyzed correlations of affection considering the colors constituted through variation of tone and chroma, and the culture and race in the representative color groups constituting a visual display. The results of this study are predicted to be utilized in coordination and selection of colors viewed from an automotive visual display taking into account culture and race.

  • The purpose of this study is to research the similarity and difference of color application in the culture of Korea and Japan. The subject of this research is the costume color of Changgeuk and Kabuki. This survey analyzes Munsell's 3 attributes(Hue, Value, Chroma), tone, and 3D color analysis by extracted color data. And representative color according to Obangsaek is proposed. The results of this study are as follows: 1. High chroma red in Kabuki costume is more used as symbolic color(passion and luxurious) in order to show character's personality than that in Changguek costume. 2. Low chroma YR color(no-dyeing color) in Changgeuk costume much more used because of Korean white robe preference and eco-friendly thinking. But high chroma yellow is restrictive color for symbolic color of emperor in Korea and Japan. 3. Blue is most frequently used in both costumes because blue is encouraging color by the theory of exponents of the five elements doctrine. 4. White in Korean Changguek costume is more used for white robe preference thinking, but black in Kabuki costume is much more used for symbol of power in Japan. The similarity of Korean and Japanese cultural color is to use much Obangsaek, less Ogansaek by the theory of exponents of the five elements doctrine, but the difference of Korean and Japanese cultural color is to use color differently according to preference thinking system.

  • 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.
