The effect of color, as measured on the spectrometer, on the 4 basic tastes(sweet, salty, sour & bitter) perception of a series of colored and no-flavored solutions was quantified by 16 taste panel using magnitude estimation without modulus. The regression lines for each colored series were found to differ indicating that color had a significant effect on sweetness, sourness and bitterness. A sucrose level of 4.0%, a citric acid level of 0.05%, and a nicotinamide level of 0.08% maximized the effect of color on taste's perception and its acceptability. Although color tended to confuse the perception of saltiness, this effect was not significant except for yellow solutions.

The purpose of this research is to study face images according to color of make-up was made by computer graphic simulation. The various facial images can be helpful for choosing suitable make-up color planning. In order to find out the differences of face images by make-up color, three different foundations and seven eye-shadows, six lips were applied on the round face model. Make-up Image Scale was used the scale of seven point modified the S-D method. Data were analyzed by Varimax perpendicular rotation method, Duncan's Multiple Range Test, Three-way ANOVA. As the result of make-up image perception analysis, a factor structure was divided into mildness, modernness, elegance, unique. The factor of mildness, modernness, unique affected on the foundation color. Foundation color was found out to be influential variable to distinguish color perception abilities. Also, the foundation, eye-shadow, lip color were influenced interactively on the perception of elegance factor. Pink color was important color, influenced on the mildness factor. Gray and purple color were influenced on the modernness factor. Mildness factor was perceived as the most bright foundation but unique factor was perceived as the most dark foundation. Then, the foundation, eye-shadow, lip color were influenced interactively on the perception of facial images. The results can be effectively applied to today's marketing and color design management which is focused on the product's emotional image in customer's mind.

This study suggests the optimum interior environment by projecting the criteria to design the living space light-ing that select the lighting environment among the sever-al environmental factors that influenced on the human perception. As a correspondance between the visual perception and the lighting, visual perception process, vision system, and visual perception system are investigated to compre-hend the lighting, and then conceptual contour of the lighting environments are presented which are transmit-ted the visual informations. As a lighting factors which are influenced on the visu-al perception, light source color is analized. Foundationally, the effect of the lighting methods and the techniques are investigated, and the changes of the lighting methods which influences on the space perception are examined through the previous results. As the changing the light sources color, the changing the subjective feelings of space perception through the ex-periment. This study is concluded with the proposition of the ef-fective lighting and the importance of the lighting envi-ronment.

Aging brings color-weakness to the eye due to yellowed eye sight. The 87% of information required for human behavioral decisions are visually perceived. Therefore, the color-weakness will affect behavior in many ways. Most of previous research regarding color planning for the aged focuses on discovering their preferred colors and reflecting the colors on facility color planning. But such research failed to identify the confused range of color cognitions due to the color weakness of the aged. The purpose of this study is to propose a design guide for fee-charging residential facilities for the elderly, reflecting upon color perception characteristics. An experimental simulation on aged vision using the UV filter and Y-2 filter, YA-3 filter alternating for general eyesight, 70 year-old and late 80 year-old was conducted. The results of this study are as follow : color perception is changed by crystalline lens aging process and yellowed eye sight. The recognition arrangement of colors was preferred to contrast harmony rather than similarity harmony and the dominant color is a warm color rather than a cool color.

The objectives of this study were to investigate the effect of the color of jacket. dress shirt, necktie. and perceiver's gender on image perceptions of male, and to examine how clothing color preferences varies according to perceiver's gender and age. The stimuli of 8 pictures of male and the semantic differential scale were used to evaluate image perception. Subjects were 192 males and females in Seoul. The colors of jacket gave significant influences on perception of potency. elegance, preference, and manliness. The colors of dress shirt gave a significant influence on perception of manliness, the necktie's colors gave influences on elegance and visibility. Perceiver's gender did not give significant influences on the image perception. Visibility had an interaction effect by the colors of jacket and dress shirt. Potency and preference evaluation had interaction effects by the colors of jacket. dress shirt. and necktie. White dress shirt had positive effects on the perception of potency and preference in the case of matching with dark blue jacket and red necktie, and blue shirt had a positive effect on the perception of potency and preference in matching with dark blue jacket and blue necktie. The preference of dark grey suit and black shirt showed significant differences according to gender. Dark blue suit, white shirt, and blue shirt had significant differences according to the age group.

The purpose of this study was to examine the differences in the clothing image perception of elderly women according to the clothing types, the clothing colors, the perceiver's sex-role attitude, and gender. Result of factor analysis revealed that the dimensions of clothing image perception was classified into four categories: evaluation, youth, warmth, and activity. Perceiver's sex-role attitude and gender gave a significant influence on the perception of evaluation factor. Youth factor had an interaction effect on the clothing types, clothing colors, and sex-role attitudes. The persons with a conservative sex-role attitude perceived the clothing image of warm color suits as younger than the one of cold colors. The clothing image of a warm colored Hanbok (Korean traditional dress) was perceived milder than a cold one, but there were no difference in suits. Bright color suits make the wearer look younger, and cold color suits make the wearer look active. The clothing color had greater influences on the warmth and the evaluation factor than clothing types. Persons who have a conservative sex-role attitude perceived the differences according to clothing types and colors in a traditional way. It could be certified that perceiver's sex-role attitude was one of the variables influencing his/her perception in social interaction.

본 논문은 인간의 Perception을 기준으로 인간이 구분할 수 있는 다양한 Display들의 Color Gamut 체적들을 정량적으로 평가하는 방법을 제안하였다. 기존의 Color Gamut의 크기를 구하는 방법은 CIE-u'v' 좌표계에서 R, G, B Primaries의 좌표에 해당하는 꼭지점으로 이루어진 삼각형의 넓이를 구함으로써 표현할 수 있는 Color의 개수를 구하였다 그러나 이 방법은 CIE-UCS Chart 자체가 2 Dimension이고, Non-Uniform Color Space이므로 정확하게 구했다고 할 수 없다. 이를 해결하기 위하여 본 논문에서는 Uniform Color Space 인 CIE-L/sup */a/sup */b/sup */ 좌표계에서 3 차원 공간에서 Color의 개수를 구함으로써, 구분할 수 있는 Color Gamut의 체적을 인간의 Perception을 기준으로 평가하는 정량적인 기법에 대해 논하였고, 이를 4종류의 다양한 Display Type들에 적용, 그 결과를 비교하였다.

Mobile display panel is small so that users are often difficult to perceive images clearly. About image we perceive much through colors and therefore we propose color fitting approach for clear perception even on the small and low quality LCD panels. Various color modifications have been studied and used in commercial software packages. For mobile usage, our approach instantly enhances color images by modifying colors in a way to contrast differences of them. The method includes tone enhancements (which contrast dark and bright sides) and color enhancements (which reduce saturation for pure colorants). Based on color theory, our method also modifies color values towards specified complementary and preference colors. We term this color fitting. This approach enables displaying photos, multimedia messages, videos and digital media broadcasting (DMB) for better perception in real-time on mobile devices.

The objectives of this study were to investigate the effect of perceiver's fashion involvement, clothing color, and background of object person on image perceptions of clothing, and to examine how clothing color preference vary according to perceiver's fashion involvement. Subjects were 273 college women in the metropolitan area of Seoul. The T-shirt was changed into 11 colors by using the CAD system. Five factors were derived to account for the dimensions of image perception. These were individuality, elegance, femininity, activity, and neatness. Perceiver's fashion involvement gave a significant influence on perception of individuality. Clothing color gave significant influences on 5 image dimensions. White and beige were evaluated neat image. Neatness factor had an interaction effect by fashion involvement and clothing color. The high involvement group evaluated white and beige shirt more neatly, and orange and yellow less neatly than the low involvement group. Individuality and elegance had an interaction effect by fashion involvement and background of object person. The high involvement group liked red, violet, and black shirt more than the low involvement. Refined and becomingness image gave significant influences on clothing color preference in both high and low involvement groups.
