  • We investigated color changes on the outer surfaces of Phyllostachys bambusoides bam-boo by heat treatment under three different temperatures (180℃, 200℃, and 220℃) for three different durations (60 min, 90 min, and 120 min). A method of predicting the bam-boo surface color change after heat treatment was developed to provide valuable information and increase the added value of domestic bamboo products. The three average color parameters L*, a*, and b* decreased, and the overall color changes increased as the severity factor increased. The values of L* × a* × b* were highly related to the severity factor, and the optimal duration time for the desired bamboo surface color with a certain heat-treatment temperature could be estimated.

  • Symbolizing holiness, wealth and power, golden color was most effective to express the absolute power of royal family and aristocratic society as well as the beauty of magnificent and brilliant authority. Such golden color was understood as the artistic color formed in the dictatorial society as well as the society under the rule of absolute monarch. Thus, it has been used in the costume that symbolizes nobleness, holiness, brilliancy, ethnicity and future-oriented property. In this sense, the image of golden color shown in contemporary fashion was analyzed as follows in this research: First, showing the future-oriented image, golden color expresses avant-garde, cyber and cosmic future-oriented image by using diverse new materials which introduce the state-of-the-art technology sense in addition to metallic textile. Second, getting hint from the ethnic costume of many countries around the world such as brilliant embroidery using golden-thread, ornament with exaggerated technique such as gold foil, mark and character in peculiar tint, the ethnic image of golden color expressed the peculiar color or materials of ethnic costume, handicraft details, etc in golden color. Third, since golden color is expressed in ostentatious image to which elegance and luxuriousness that looks like the work of haute-couture costume of royal family or sensuality that voluptuously expresses the beautiful body line of women are added, the viewers are enchanted or attracted.

  • The aim of this study is to develop an effective dyeing process for black color on the silk fabrics, using natural Indigo, Madder, Amur cork tree, Alder, Logwood, and Gallnut. All natural dye materials were water-extracted, concentrated, and freeze-dried. Seven different processes were carried out and the color differences(${\Delta}E$) of black color with each process from the chemical black dyed fabric were compared. The light, washing, and rubbing fastness were evaluated. The black dyeing of the silk fabrics was well carried and excellent black color was obtained in every methods. The profound black color could be obtained by the subtractive mixture of the three primary colors of red, yellow, and blue in the order of indigo(blue) - amur cork tree(yellow) - madder or lac(red). Black color was efficiently obtained by iron mordant when logwood or alder fruit was used. The color difference(${\Delta}E$) from the black color with chemical dyestuff was the lowest in the indigo - amur cork tree - lac - iron method. Light fastness and washing fastness were excellent in all dyeing processes, showing grade 5. The fastness to rubbing was excellent as shown grade 5 in the dry samples of logwood - iron process and alder fruit - iron process.

  • This experiment evaluates wintering ability to maintain green color of lawn grasses during winter and investigates the effects of top dressing of fertilizer on improving green color during regrowth. Kentucky blue-grass could maintain green color and leaf chlorophyll content better than tall fescue and creeping bentgrass in winter. All three grasses in this experiment have shown the excellent wintering ability. In enhancing the recovery of green color at the early stage of regrowth, the mulching effect with rice straw was highly significant for creeping bentgrass. Green color recovery in grasses during its regrowth was better at the top dressing plots than at the plots without top dressing, but when fertilizer application levels were increased, green color in lawn grass did not significantly change. Although green color in tall fescue, Kentucky bluegrass, and Korean lawngrass could be maintained during summer, the green color of creeping bentgrass is reduced significantly with high temperature. Top dressing after winter and mowing improved leaf chlorophyll content and green color in tail fescue and Kentucky bluegrass significantly. However, Korean lawngrass did not respond significantly with increased levels of fertilizer.

  • 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.

  • This study investigated the digital color profiles corresponding to different maturity stages and levels of brown croaker Miichthys miiuy specimens collected from the Southern Sea of South Korea. Maturity stages were determined using photomicrographs of ovarian developmental phases, which were compared with digital color values. Brown croaker specimens ranged from 24 to 81 cm in standard length; mature ovaries were predominantly observed in specimens that exceed 40 cm in length. Monthly ovary color values were primarily concentrated in the 1st and 4th quadrants, with both a* and b* values falling within a range of ±15 centered on the origin. Similarly, the testes color values were predominantly situated in the 4th quadrant, with a* and b* values ranging from -5 to 15 and 10 to 14, respectively. While the color values of the mature and spawning stages overlapped within a narrow range, distinguishing between them required both the color value and monthly color value distribution to be considered. Thus, this study underscores the efficacy of digital color measurements for assessing brown croaker gonad maturity, and provides more quantitative insights compared to subjective visual assessments by humans.

  • This paper proposes the color of car that accident occurs in color from the highest probability to lowest probability. This is talking about the color difference of advancing color and receding color. The color of the accident-prone is many receding color that actually seem to be far more. Advanced color that seems to be closer than the actual color find out that accident is less.
