Color, an important visual cue, can cross-modally affect odor association and odor quality identification Here, this research investigates aspects of the cross-modal associations between color and fragrance in greater depth, delving into the topic of whether the degree-of-association of fragrances with hue and tone of colors varies systematically. For 33 color stimuli (10 hues, 3 tones, and 3 achromatic colors), 67 subjects judged the degree-of-association of four typical fragrance families (fresh, floral, oriental, and woody) on a 7-point scale. The statistical analysis showed that fragrance associations of the all families had characteristic distributions across ten hues of the color stimuli. The cross-modal relationship between color tone (especially, lightness attribute) and fragrance association appeared to be dimensional (e.g. a positive linear relationship between the floral family and the lightness). More specifically, as colors became warmer and brighter, the associated floral scents were stronger, while the woody scents was less associated. Brighter or more vivid cool colors were associated with stronger fresh scents. These findings confirm the systematic existence of synthetic interactions between vision and olfaction in perfumery.

The sensibility effects of color combinations was studied utilizing tone on tone combination and tone in tone combination. A total of 24 color combinations were rated by 10 college students using Semantic Differential Method. The data was analyzed by using Excel statistics program 2004. Analysis method was factor analysis. Theresults of this study were as follow. Color combinations utilizing tone on tone and color combinations utilizing tone in tone was evaluated a very different impression. Thus these were found to have an influence on sensibility effects of color combinations. In comparison with appearance of color combination using colored paper and that of product to apply to color combination using colored paper, it was showed to be evaluated mostly similar impression. However By characteristic with product, shape, size and texture, appearance of color combination is likely to be evaluated very difference impression. The results of these studies will serve as a basis of color combination image or color design.

The purpose of this study is to investigate the effect of eyeshadow color (brown, purple, and blue), lipstick color (red, red purple, and yellow red), and lipstick tone (vivid, light, dull, and dark) on impression formation. Sets of stimulus and response scales (7 point semantic) were used as experimental materials. The stimuli were 36 color pictures manipulated with the combination of eyeshadow color, lipstick color, and lipstick tone using computer simulation. The subjects were 216 female undergraduates living in Jinju city. Impression factor of the stimulus was composed of 4 different components, attractiveness and gracefulness, visibility, cuteness, and softness, of which the first two were important. Eyeshadow color, lipstick color, and lipstick tone independently influenced the attractiveness and gracefulness and visibility. In the cuteness and softness, eyeshadow color and lipstick tone showed independent effect. In the interaction effect, the combination of lipstick color and lipstick tone showed significant effect on the attractiveness and gracefulness, visibility, and cuteness. Finally, it was found that the combination of eveshadow color and tpstick tone showed significant difference in the softness.

Recently, the HDR imaging technique that mimics human eye is incorporated with LCD/LED display devices to deal with mismatch between the real world scene and the displayed image. However, HDR image has a veiling glare limit as well as a scale of the local contrast problem. In order to overcome these problems, several color correction methods, CSR(center/surround Retinex), MSR (Multi-Scale Retinex), tone-mapping method, iCAM06 and so on, are proposed. However, these methods have a dominated color throughout the entire resulting image after performing color correction. Accordingly, this paper presents a new color correction method using dynamic cone response function. The proposed color correction method consists of tone-mapping and dynamic cone response. The tone-mapping is obtained by using a linear interpolation between chromatic and achromatic. Thereafter, the resulting image is processed through the dynamic cone response function, which estimates the dynamic responses of human visual system as well as deals with mismatch between the real scene image and the rendered image. The experiment results show that the proposed method yields better performance of color correction over the conventional methods.

The purpose of this research was to compare the harmony of tone on tone coloration according to transformation of color area-ratio in traditional Korean dress. The respondents were asked to evaluate 36 stimuli of the traditional Korean skirt and jacket with different color tone. The subjects were 83 female undergraduate students. The results are as follows. For red colors, combinations of vivid/dull, vivid/dark, and light/dark made a difference in the harmony of coloration according to the transformation of color area-ratio. For yellow colors, combinations of vivid/dark, light/dull, and light/dark made a difference in the harmony of coloration according to the transformation of color area-ratio. For green colors, combinations of vivid/dull, vivid/dark, light/dull, and light/dark made a difference in the harmony of coloration according to the transformation of color area-ratio.

마티즈와 같은 유명한 화가들의 작품을 보면 쉐이딩 부분을 단순히 회색 톤을 이용하여 색을 칠하는 것이 아니라 표현하려고 하는 상황과 분위기에 맞추어 다양한 색을 사용하는 것을 확인해 볼 수 있다. 이렇게 다양한 색상을 이용함으로써 장면을 작가의 의도에 맞게 연출할 수 있을 뿐 아니라 풍성한 느낌을 줄 수 있다. 이는 색이 인간의 감성적이 부분을 자극할 수 있기 때문인데, 사용하는 색에 따라 사람의 느낌도 변하고 감정도 달라지기 때문에 작가들은 다양한 색의 조합으로 느낌을 표한 할 수 있는 것이다. 본 논문에서는 3차원 렌더링에서도 다양한 색으로 쉐이딩 할 수 있는 다중 층 색상 쉐이딩 기법을 제안한다. 기존의 퐁 쉐이딩 기법이나 카툰 쉐이딩 기법은 단순히 회색 톤을 이용하여 쉐이딩 처리를 한다는 문제점이 있다. 이러한 문제점을 해결하기 위해 쉐이딩 범위를 여러개로 나누고 각각의 영역에 반투명의 색을 덧칠함으로써 자연스럽고 풍부한 색의 혼합이 가능하도록 하였다. 이러한 다양한 색을 사용함으로써 3차원 렌더링에서도 다양한 장면 연출이 가능하며 느낌 표현도 할 수 있다.
