최근 젊은 층을 중심으로 웰빙과 다이어트가 트렌드로 자리 잡으며 탄산음료보다 설탕과 인공첨가물 등이 첨가되지 않은 탄산수의 소비량이 급증하고 있다. 이에 국내 탄산수 시장이 엄청난 성장세를 보이고 있으며 국내 외 탄산수 브랜드간의 경쟁이 치열해 지고 있다. 이러한 시장에서 경쟁력을 확보하기 위해서 소비자의 구매 욕구를 결정하는 중요한 요소인 패키지 색채의 연구가 필요하다. 본 연구는 현재 국내에서 유통되고 있는 국내 외 탄산수 각각 5개를 지정하여 패키지의 주조색과 보조색을 구분하고 비교분석하였다. 분석결과 한색계열의 색채를 주로 사용하는 국내 탄산수 패지키는 다양한 색채를 사용하는 수입 탄산수 패키지보다 주목성이 떨어짐을 알 수 있었다. 본 연구의 결과가 국내 탄산수 패키지 디자인의 경쟁력 강화에 도움이 되기를 기대한다.

색채에 따른 목표자극과 방해자극의 분리가 2차원 운동지각을 향상시킨다는 연구결과(Stoner & Albright, 1997)와 색채에 따른 목표자극과 방해자극의 분리가 2차원 운동지각을 향상시키지 못한다는 상반된 연구결과(Edwards & Badcock, 1996)의 모순을 해결하고, 선택적 주의에 따른 목표자극과 방해자극의 분리가 2차원 운동지각에 미치는 영향을 연구하기 위하여 일련의 실험이 수행되었다. 이러한 연구문제에 대한 이형철(1999)의 연구가 있었지만, 이형철의 연구는 단지 숙련된 2명의 피험자의 결과에 의존했다는 점, 그리고 선택적 주의에 사용된 자극에서 목표자극과 방해자극이 색채에 의해 완벽하게 분리되지 않을 때와 목표자극과 방해자극이 색채정보에 의해서만 분리되고 그 외의 다른 정보에 의하여 분리되지 않을 때와 목표자극과 방해자극이 그 어떤 정보에 의해서도 분리되지 않을 때, 피험자들의 2차원 운동지각 수행은 비슷하였다. 하지만, 목표자극과 방해자극이 색채정보에 의하여 분리되고 피험자들이 목표자극을 구성하는 색채에 선택적 주의를 기울일 때, 피험자들의 2차원 운동지각 수행은 향상되었다. 이러한 실험결과는 선택적 주의가 개입되지 않는 한 인간의 운동지각체계는 자극 구성요소들을 운동정보분석을 위해 색채에 따라 자동적으로 grouping 하지 않음을 의미한다

Technology in digital video has changed the functions of the digital video field based on various platforms, including streaming, on-demand, interactive, and data-based services. The displays that provide the visual representations of these digital video contents have also been improving with various changes. There is a variety of display screen ratios currently available, with the ratio of the display screen being based on the intended purpose. This study conducted a psychophysics experiment to examine the correlation between colour properties and shape ratio based on the display screen ratio, and then analysed the results. The colours used in the experiment were visual perception-based Munsell colours, and the hue, brightness, and chroma attributes were analysed according to the shape ratio to examine colour properties. The analysis of the results of this study defined the significance of the study as basic data for future studies on colour property changes based on shape ratio, and suggested directions for future studies.

This study was carried out in order to investigate color sensation and sensibility for yellowish natural dye fabrics and reddish ones and to establish prediction models for color sensibility factors of them by color sensation and the related physical measurements focusing on 40s middle-aged people. Eight fabric stimuli which were dyed with a variety of yellowish or reddish natural dyes was subjectively evaluated in terms of color sensation and sensibility by 40s aged participants. As results, three color sensibility factors including 'Active', 'Characteristic', and 'Relax' were extracted and they were examined in respect of their relationships with color sensation and physical color properties. Color sensibility factor 'Active', the dominant factor for the naturally dyed fabrics was explained by $L^*$ and sensation 'Deep' in its predictive model and a yellowish fabric dyed with 300% solution of armur cork unmordanted was perceived the strongest in the factor. Factor 'Characteristic' was predicted by both $a^*$ and sensation 'Light' and reddish natural dye fabrics tended to be felt more strongly for it. Color sensation 'Strong' was the only predictor for factor 'Relax' in that naturally dyed fabrics with lower values for the sensation seemed to show higher 'Relax' factor and a reddish fabric dyed with safflower 125% was the highest for the color sensibility factor. These results could be utilized to design color-sensible natural dye fabrics for middle-aged people.

This study was to estimate human response to different color light stimulation by measuring physiological parameters of human behavior, For both stimulations we used color lights with 6 color filters such as red, yellow, green, blue, violet, and white. The experiment was performed in a soundproof chamber. 30 young male and female subjects participated in the experiment, For physiological parameters, we measured electroencephalogram (EEG), electr ocardiogram (ECG). The result of EEG analysis showed that the relative power of $\alpha$ wave ratio increased in blue and green, In case of HRV spectrum analysis, HF/LF ratio increased in green and blue. From these results, we knew that the physical response was affected by color environment and it might be an indicator in the design of a color environment.

Importance of color in floral design has been emphasized for long time, but it is difficult to find out standardization of color for floral design and for educational system. Wedding bouquet is major and important part of floral design and it shows same problem. The research is concentrated on color image analysis of wedding bouquet designs which have been submitted for 'Interflora World Cup Competition' with the intention to utilize the study result as the basic information of floral design. Colors of wedding bouquets from 20 different countries were analyzed. All of designers chose high brightness and saturation more for designing the bouquets. Warm colors and cold colors have been taken in similar portion. Blue color has been rarely used and it is probably because of the rarity of blue flowers. This study shows each continent has different color preference. European designers used wide variety of colors while Asian designers preferred red color. From this study, we found that color image scales of wedding bouquets represent 8 images out of 12 representative images. Four exceptions are 'clean', 'elegant', 'gentle' and 'modern' images.

This study was performed in order to suggest useful data for color planning of eco-friendly and sensible fashion products. Silk fabrics were dyed in combination with natural indigo and Japanese pagoda tree and were treated with four kinds of mordants after combination dyeing. Then, their colorimetric properties were evaluated. From these composite-dyed silk fabrics, color sensibilities and color preferences of green yellow (GY) color were evaluated among the female university students, and thus, the influences of colorimetric properties and color sensibilities on color preferences were analyzed. When the silk fabrics were dyed in the combination of natural indigo and Japanese pagoda tree and were treated without mordants, they turned green color when indigo 10 g/L was used, and blue-green when indigo 20 g/L was added. And when they were dyed in combination of natural indigo and Japanese pagoda tree and were treated with four kind of mordants after combination dyeing, they turned GY color in almost all cases. The color sensibilities of the GY silk fabrics with the combination dyeing of indigo and Japanese pagoda tree, were classified into three factors: pleasantness, gracefulness, and comfort. Color sensibility factors showed significant differences according to the concentration of indigo and the kinds of mordants. There were almost significant relationships between colorimetric properties and color sensibilities factors of compositely dyed GY silk fabrics. The color preferences of the GY fabrics, which were dyed in the combination of using natural indigo and Japanese pagoda tree and four kinds of mordants, were found to be predicted by the color sensibility in a regression model.

In recent, many researches have been studying sensitivity and psychology of human being on color and the necessity of psychology therapy by color. Among them, a picture of children can be a tool to represent their emotion. Information of colors and direction on a child's picture often represent his internal psychological states unconsciously and is different from the brightness of a color. In this paper, we propose a method to extract domain colors by color classification and subdivision the classes of brightness using fuzzy inference. In addition, it is shown that our method is used for analysing the psychology status of children through their pictures.

This is a basic research aimed at enhancing a brand image by unifying color images of a brand at both online and offline stores. h survey was conducted on color images of online and offline stores to measure the level of consistency between consumers' perception of the color image and the brand's color strategy. A brand preference survey was also performed to shed light on the relationship between the brand preference and the consistency of color images at online and offline stores. This study is committed to building an effective color strategy, based on the brand strategy, through web color planning that is consistent with the offline color image. This paper started with a specific purpose of devising solutions in regard to the prior study, entitled 'Study on Color Strategies in Brand Coffee', which recognizes the need for consistent color images, or integrated color strategies, in online and offline stores. I specifically took the approach of looking at color planning in the stage of designing a website. Two standards were used to analyze emotional and functional aspects of color images: color grading by I.R.I and five communicators of color information by Rouge. Direct visits were made to the offline stores for surveys to address the shortcomings of the prior study, in which offline stimuli were limited to printed materials. The direct visits enabled a study of an overall color image of the offline stores, while providing a set of substantial and specific guidelines for designing colors for a website. I hope this study goes a long way toward enhancing the level of consistency between online and offline color images based on the brand's unique color strategy, and thereby improving the overall level of brand image.
