식품의 맛은 미각, 후각, 시각, 청각, 촉각에서 느낀 여러 가지 인상과 개인의 경험이나 기호가 복합적으로 적용되어 인식된다. 특히 맛을 결정하는 영향 요인 중에서 시각을 통해 인지하는 색은 실제 맛을 지각하기 전에 맛에 대한 이미지를 연상시킴으로써, 식품 선택에 결정적인 영향을 준다. 따라서 식품색을 적용함에 있어 식품 자체의 맛 이미지를 효과적으로 전달할 수 있는 색을 활용함으로써, 소비자들이 좀더 관능적으로 선호할 수 있는 식품을 개발할 수 있을 것이다. 본 연구에서는 소비자들이 특정 식품을 선택하여 구매하고자 할 때 인지하게 되는 맛 이미지를 효과적으로 전달하기 위한 도구로서 색채를 사용하기 위해 사례연구를 진행하였다. 사례연구는 초콜릿색에서 연상되는 맛에 관한 웹 설문을 통해 진행되었다. 설문 결과를 바탕으로 식품색에서 연상하게 되는 맛에 영향을 주는 요인을 추출하고, 초콜릿 맛의 종류와 느낌의 정도에 따른 주요 색채의 경향성을 도출함으로써 시각을 이용하여 보다 정확하게 초콜릿 맛의 공감각적 특성을 전달하기 위한 기초자료를 제안하였다.

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 purpose of this study was to investigate the effect of perceiver's gender, clothing, and hairstyle on the visual evaluation of men's professionalism and preference. A quasi-experimental method by questionnaire was used. The experimental design was a $2\times8\times2$ (perceiver's gender $\times$ clothing $\times$ hairstyle) factorial design by 3 independent variables. The stimuli were 16 photographs of a man in his twenties. The upper clothing of the man included tailored collar jackets in beige and dark blue colors, and jumpers and sweaters in beige, dark blue, and red colors. The lower clothing of the men included jean pants. Two types of the hairstyles included short hair and medium length hair. The subjects were 208 men and 223 women in Seoul, Korea. Wearing a beige sweater with jean pants was evaluated high in intellectual image, a red jumper was perceived low in intellectual image, and a beige tailored collar jacket was evaluated low in potent image. Men's short hairstyle was evaluated to be more professional than the medium length hair. Male perceivers liked short hair more than medium length hair, but female perceivers evaluated both hairstyles similarly. In the case of women, the preferences of tailored collared jacket and soutien collared jumper were similar, but jumper was preferred to jacket in the case of men. Male perceivers showed more positive feedback towards jean pants with soutien collared jumper than jeans with tailored collared jacket, which indicated that men showed more conservative attitude towards the outfit than women. The man who was wearing a jumper with short hair was evaluated positively and the man who was wearing a jacket with medium length hair was evaluated negatively when the attires were coordinated with jean pants. In conclusion, medium length hairstyle with a beige jacket and short hairstyle with a red sweater were evaluated as professional image; and the results indicated that clothing and hairstyle interact with each other and influence the evaluation of professionalism.

Colors, as a part of contents, have great implications to consumers. Each individual feels the image of colors as an outcome of the accumulated experience or knowledge of oneself. This study aims to find the personality and meaning of color images through the predicted trend colors and to analyze the consumers' attitude towards them. We found that the 5 major trend colors such as Crystal Sound, Creamy Touch, Mysterious Vintage, Autumn Forest and Carnival seem to have their own personality images. Furthermore, we discovered that Crystal Sound has an image of a self-made man, Creamy Touch a highschool girl, Mysterious Vintage a God father, Autumn Forest the public and Carnival a circus clown as a result of additional adjective image analysis. In addition, customers marked the highest preference for Creamy Touch. The research result shows that the personality of an individual and that of colors are coincide and it might bring about a positive consumer behavior. And this research has a significant meaning since it is a sort of interdisciplinary study in-between fashion and marketing and it should be studied further later.

The purpose of this paper is to investigate the readability of Nearly White background color in display environment. To perform the experiment, warmup experiment was carried out to for cognitive of whiteness using a Tablet PC. The experiment environment was by a indoor window seat under a mixture of fluorescent light and sunlight. The result of previous test was that the most whiteness perception was a color white a medium wavelength and followed by the short wavelength. The main experiment was to find readability, color combination and visual strains using 4 nearly whites background colors (Reddish, Greenish, Blueish, Yellowish) and one white background color, also text color is limited on black. As a result, readability and color combination had the highest score against a Greenish white background. Visual strain is also the lowest against a Greenish background. On the contrary, readability and color combination preference has the lowest score against the Reddish background. Visual strain is also the highest against a Reddish background. We propose the background color, which improves readability and reduces visual strain in visual display terminals environment through the research results.

Additive color mixture of two different background colors appeared in the afterimage of a gray circle centered on an isoluminant bichromatic background (red/green, blue/green, or blue/yellow background). The chromatic mixture still appeared in the afterimage of a gray circle on a bichromatic background at different luminance levels, and also appeared in a large test field. The saturation of the induced color was observed to increase as the overall luminance of adaptation background stimulus increase of the size of test field decreases. It was found that the chromatic mixture does not appear with a chromatic or achromatic boundary inserted on the center of the test field. The boundary seems to prevent the induced color on each side of test field from spreading to the other side so that the induced color does not appear mixed but divided into two different colors. Without a boundary on the test stimulus, the color information induced in the afterimage seems to be too weak to create a subjective boundary between the two colors and consequently propagate inward appearing mixed.

Two experiments were conducted to investigate the impact of binocular disparity information on Neon color spreading (NCS). The stimuli was the modification of Ehrenstein figure used by Redies and Spillmann(1981); inner and outer segments were achromatic and middle segments was chromatic. In experiment 1, the effect of binocular disparity was tested in each segment that were divided inner, middle and outer segments. In experiment 2, the impact of added segments that were put in different depth place were tested. The results showed that the segments on same place were, the clearer the NCS was. Consistent with the previous studies, the effect of color segment in front or in behind was not appeared. The case of added segments, regardless of added segments were placed either front or behind, the NCS was reduced. But the effect of added outer segments was more affect then added inner segments. This results were suggested that NCS could be affected by depth information but more affected by stage of before depth processing.

This paper describes color clustering method based on color difference in the uniform Munsell color space obtained from hue, saturation, and value. The proposed method operates in the uniform HSV color space which is approximated using ${L^*}{a^*}{b^*}$ coordinate system based on the RGB inputs. A clustering and color difference evaluation are proposed by thresholding NBS unit which is likely to Balinkin color difference equation. Region segmentation and isolation process are carried out ISO DATA algorithm which is a self iterative clustering technique. Through the clustering of 2 input images according to the threshold value, satisfactory results are obtained. So, in conclusion, it is possible to extract result of better region segmentation using human color perception of the objects.
