Natural dyes have poor colorfastness as a result of the exposure of the dyed fabric to sunlight encountered during the display or wearing. As colors on fabrics fade excessively under sunlight, it is a problem to infer and restore the historic textiles with natural-dyed fabrics to original colors. The object of this study is to analyse the factors affected to color change under light. In experimental, fifteen natural dyes were dyed by the Korean traditional dyeing methods onto natural fiber fabrics: cotton, silk, ramie, and flex. Total 49 dyed fabrics in combination with dyes and fibers were used for the specimen. The Weather-O-meter was used for evaluating the effects of exposure to light for 2.5 to 450 hours. The process of color changes in the CIEL *A*B* color-order system to the exposure time were determined by spectrophotometer at 10$^{\circ}$ observer. Sunlight exposure caused significant changes in the color of natural-dyed fabrics. The degree and nature of color changes on the fabrics were dependent on the combination of fiber and the type of dye used. The groups of violet(Lithospermum erythrorhizon Sieb.et Zucc.) and black color(Ailanthus altissima Swingle, Phus trichocarpa Miq) yielded excellent colorfastness to light. The group of indigo blue color(Polygonum tinctorium Lour.) was also very resistant to fading in both exposure except silk. Whereas the dye groups of Red, Yellow, Orange, Brown colors indicated greatest changes in fading, particularly Carthamus tinctorius L.

A Study on the color comparison of Korean Saek-dong and Italian futurist fashion It is generally recognized that the color scheme and its characteristics as a product of living culture are strongly reflected in clothing. This study concentrates on the color comparison of Korean Saek-dong which has been used in traditional Korean clothing and Italian futurist fashion which showed dynamic characteristics and brilliant colors. The purpose of this study is to investigate the external format, emotions, functions and meanings of the colors in Korean Saek-dong and Futurist fashion, and to find similarities and differences between them. The results of the study are as follows. The similarities between them are harmony of vivid colors like a rainbow, no-use of black color and expression of rhythm through repeated geometrical shapes. They have been used as festive costumes and have implied meaning of happiness and pleasure. The differences, in the external formats, are as follows. Korean Saek-dong has striped patterns including the color white, and has regular distances among the stripes. But, Futurist fashion includes luminous or fluorescent colors and metallic colors. In addition, it has repeated motifs of geometrical shapes and geometrically divided areas. While Saek-dong expresses Sangsaeng through the conceptual use of color, Futurist fashion shows simultaneity, speed and dynamics through spiritual functions of crossing and inter-penetration. In emotional aspect, Saek-dong expresses pleasure of children's mind and Futurist fashion expresses pleasure of city. In functional aspect, Saek-dons expresses a concept of ceremonial beauty, which is spiritual and symbolizes good auspices, holiness and sorcery. So it is used for ceremonial costume. But, Futurist fashion reflects the harmony of colors created from modem and urban images and shows the willingness and emotion of solving futuristic avant-garde, modernity, dynamics, transformation and bellicosity. So it is used for daywear. While Saek-dong represents succession of tradition, Futurist fashion represents resistance of tradition in cultural aspects.

Purpose - Color is perceived to have an effect on humans' cognition and behavior because of its association with specific concepts. Since there are few studies linking color and price presentation, we investigated a constrained condition of consumers' regulatory focus and involvement. Research design, data, and methodology - We performed a 2 (color: red vs. black) × 2 (regulatory focus: prevention vs. promotion) × 2 (involvement: high vs. low) test of our hypothesis. The target product was a portable data storage device (USB) and data from 165 respondents were analyzed. Each condition had two stages. In the first, product information and price were presented. After reviewing the product information, respondents evaluated price attractiveness. In the second stage, respondents filled out regulatory focus and involvement questionnaires. The main variables were color, regulatory focus, and involvement. Therefore, we ran a three-way ANOVA (Analysis of Variance) to test our hypothesis. Results - When the price was red (vs. black), consumers perceived the red price as more attractive than the black price. However, this effect varied by situation. Specifically, in the low involvement condition among prevention-focused consumers, when the price was in red, price attractiveness was higher than when the price was in black. However, for promotion-focused consumers, there was no difference in the price color effect. In the high involvement condition, promotion-focused consumers showed stronger price attractiveness for the red price than the black price. However, the effect of price color diminished for prevention-focused consumers. That is, prevention-focused consumers did not reveal a different price perception between red versus black in the high involvement condition. Conclusions - This research contributes by academically linking the effects of color to price attractiveness, and focusing on the interaction of regulatory focus and involvement. When involvement is low, the effect of red disappeared for promotion-focused consumers, whereas the same happened for prevention-focused consumers under the condition of high involvement.

Purpose - This study was intended to provide implications for the importance of color to airlines where the image customers feel about the business is paramount. The importance of colors shown by the airline crew, an important human resource for airlines as contact workers, was investigated. We wanted to present suggestions by investigating and comparing the difference in customer attitude regarding the color of uniforms of the airline crew. Research design, data, and methodology - A survey was conducted to examine differences in perception of airline uniform color, with the research that suggests that the customer's attitude to uniform color will vary. The difference in the perception of passengers according to the colors of the airline uniforms was determined by conducting an empirical analysis. Results - Customers have a different attitude about the color of the uniform of airline's flight attendants' uniform. Full service airlines (FSC) generally have a bright, calm, neat, and heavy-handed feeling, while low-cost carriers (LCC) have a distinctive, dynamic, energetic, and cheerful feeling. Conclusions - An empirical analysis of the study found that customers' attitudes vary by uniform color for each airline. It has also been revealed that Airline's uniform color can communicate the company's goals it wants to convey.

This study examined the effects of underwear brand identity color on brand equity. A self-administered questionnaire mainly consisted of BI color, brand image, and brand equity for underwear. Five underwear brands (Calvin Klein, Yes, Solb, Venus, and Body Guard) were selected based on the frequency they were purchased in pilot study. To collect data, respondents were asked to choose a brand which they were most familiar with, and to assess BI color, brand image, and brand equity including cognitive value, emotional value and purchase intention. A total of 228 usable questionnaires were obtained from consumers aged 19 to 46. BI colors were classified into four color groups: Achromatic (white, black, gray), Vivid (red, blue, yellow), Pink, and Beige. Additionally, underwear brand images consisted of four factors: Sophisticated, Classic, Casual, and Elegant images. Findings showed significant differences in the four factors of brand image and cognitive brand value between the BI color groups. Also, the factor of cognitive value was higher for achromatic or beige brand color groups, than for vivid or pink color groups. Also, brand image factors had positive effects on cognitive or emotional brand value. Especially, the factor of emotional value was more likely to increase purchase intentions than cognitive value in the BI color groups. The implications for managerial decision marking in fashion marketing strategy were also discussed.

The color difference value of fabrics dyed with browning extracts from mushroom were as follows. 1. Two hours of dyeing depending on pH at 95℃ exhibited colors of YR and Y. The color of wool and nylon was darkest brown at pH 4, but light brown or yellow as pH increased. The color of silk was darkest brown at pH 5 and pH changes resulted in the same tendency as in wool. 2. In wool the color was changed to darker brown as time prolonged, however, there was no further color change after 9hr and value and chroma of wool declined. 3. At pH 4, the increase in temperature turned colors of sil, wool and nylon into dark brown from light yellow. 4. As the result of repetitive dyeing, colors of silk, wool and nylon gradually turned into darker brown. The repetitive dyeing was more effective in dark color and high colorfastness compared to a prolonged dyeing. 5. The amount of mordant resulted in color changes between light yellow and dark brown without various color changed. 6. In color change according to methods of mordant, post-mordant with CuSO₄·5H₂O and with SnCl·2H₂O showed colors of green and light yellow, respectively.

The purposes of this study were to evaluate the color characteristics and color sensibility of mulberry/cotton blended fabrics dyed with indigo, the natural dye, and analyze effects of them on color preferences. The values of CIE $L^*$, $a^*$, $b^*$ $C^*$, h were calculated for the color characteristics of indigo-dyed fabrics, and their hue, value, and chroma were calculated according to the Munsell color system. Fifty male and female college students evaluated the color sensibility of nine types fabrics dyed with indigo on a seven-point scale. The data were analyzed by descriptive statistics, factor analysis, Kruscal-Wallis test, correlation analysis, and regression analysis. The mulberry/cotton blended fabrics naturally dyed with indigo showed the characteristics of PB color tones, low value, and low chroma. The color sensibilities of fabrics dyed with indigo were classified into four factors: 'classic', 'sporty', 'elegant' and 'natural'. There were significant differences according to the fibers and the repeating times of dyeing in the color sensibility for the fabrics. Cotton fabrics were evaluated to be more classic, sporty, elegant, and natural than the mulberry/cotton blended fabrics, and the deeper the color, the more classic, sporty, and elegant the fabric was evaluated. The students preferred the indigo dyed fabrics which have more classic, sporty, and natural sensibility. There were significant relationships between the color sensibilities and colorimetric properties of the fabrics dyed with indigo. The color preferences of the dyed fabrics with indigo were found to be influenced by the 'classic', 'sporty', 'natural' of color sensibility.

Color is a sense signal for human to perceive being through light, and the color is divided into chromatic color and achromatic color. Chromatic color has hue, intensity, and saturation, but achromatic color has only intensity among the properties of chromatic color and doesn't have hue and saturation. Therefore it is important to split colors of image into area for human to perceive colors and not to perceive ones based on vision of human being. In this paper, we find a function to split colors of image into chromatic region of chromatic color region and achromatic region of achromatic color region. First, the input image of RGB color space is converted into the image of HSI color space in consideration of human vision and get a binary image from the converted image. After then, a function to split colors into ROC(ROC: Region of chromatic.) and ROA(ROA:Region of achromatic) is yield. It is difficult to split color of a general image into ROC and ROA. Therefore, to get the chromatic area and achromatic area, we make gradient images to have all range of intensity and range of saturation and to have a little range of hue and yield the function. The evaluation is tested using subjective-quality by 50 non-experts for result images of test images and general images. The results of the proposed method get better 27.5~32.96% than these of the conventional method

The purpose of this study is to propose the information and idea that can be applied to color planning by investigating preferred color according to ages, items by distribution of 30s~50s women. As the survey method, questionnaire survey and one-to-one investigation by preparing the color table of basic color and trend color were conducted, and total of 280 questionnaires were used for statistical analysis. The results of this study areas follows. First, in basic color, there were significant differences in preferred hues and tones by age groups. The preferred hues were N, PB in all ages, and the higher the age, the more people preferred vivid tones. Second, in basic color, there was significant difference in preferred hues of jumpers, one-pieces by distribution, and the preferred hue was found to be N in the items except jumpers. There were significant differences in preference tones of all items according to distribution. Third, in trend color, there was no significant difference in preferred hues by age groups. Preferred tones had significant differences by distribution, and the higher the age, the more people preferred vivid tones. Fourth, in trend color, some items had significant differences in preferred hues and tones by distribution. B was preferred in all age groups, and vivid tones were more preferred in wholesaler than the department store. Based on these results, this study proposed 30s~50s women's wear color planning idea that applied consumers' preferred color according to ages and items by distribution.

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.
