The purpose of this study was to investigate the sensibility image of necktie according to width and color combination of checked pattern. The experimental materials developed for this study were a set of stimulus and response scales. The stimuli were 18 color pictures, in which the width(small: 0.2cm, medium: 1cm, large: 2cm), tone combination(similar, contrast), and hue combination(WR: white+red, WB: white+blue, WG: white+gray) were manipulated. The 7-point scale was used for evaluation of sensibility image. The subjects of this research were 216 female college students living in Gyeongnam. The investigation was carried out at September 2009. The data were analyzed by using SPSS program. Analysis methods were ANOVA and Duncan-test. The results of this study were as follows.; The analyses of sensibility for necktie according to width and color combination of checked pattern revealed that the concerned factors are five characteristic dimensions of attractiveness, youth, appeal, elegance, and warmness. Width showed an independent effect on appeal. Tone combination showed an independent effect on attractiveness, appeal, elegance, and warmness. Interaction effects of width and tone combination on attractiveness were found. Hue combination showed an independent effect on all dimensions. In addition, significant interaction effects of width and hue combination on attractiveness, youth, appeal, and elegance were found. Significant interaction effects of tone combination and hue combination on attractiveness, youth, and appeal were found.

This study analyzed the influence of MBTI (Myers-Briggs Type Indicator) personality types on preferences for user interface (UI) design in music applications. Through an online survey, 535 responses were collected, and data were processed using ANOVA analysis in Python. The analysis revealed that certain MBTI types tend to prefer combinations of warm and neutral color tones, aligning with their artistic sensibilities and emphasis on harmony. Conversely, other MBTI types show a preference for colder color tones or combinations of cold and neutral tones, reflecting their practical and systematic tendencies. Additionally, it was found that UI layout preferences also vary according to personality types. Some MBTI types exhibit a preference for the 'Mostly Fluid' model, reflecting their efficient and systematic nature. These findings underscore the importance of considering users' individual personality types in UI design for music applications.

Purpose: The purpose of this study was to colorimetrically evaluate the masking effect of different opacity of ingots on the final shade of IPS Empress Esthetic$^{(R)}$ laminate veneer restorations using the CIE $L^*a^*b^*$ system. Materials and methods: Six porcelain disks of IPS Empress Esthetic$^{(R)}$ system (translucency: E 01, E 03, E 0C-1, E TC-1, E TC-2, E TC-3) were fabricated with 7 mm in diameter and 0.6 mm in thickness. Six extracted human incisors (shade: A1, A3, A4, B2, B3, C3) were used as the abutment specimens. The incisors were prepared using a diamond wheel and made with a flat labial surface on the middle 1/3. For each combination of different shades of abutments and copings, the change in color was measured with a colorimeter. CIE $L^*a^*b^*$ coordinates were recorded for each specimen. Color differences (${\Delta}E$) were calculated. Descriptive statistical analysis was done. Results: ${\Delta}E$ values were significantly affected by coping translucency and abutment shade (P<.05). The color differences (${\Delta}E$) of laminate veneers among abutments with A3, B3, C3, and A4 shade were mostly below 2.7 which was within the clinically acceptable range, while color differences between A4 and B2, A3 and B2, and A1 and A4 showed more than 2.7. Conclusion: The final color of IPS Empress Esthetic$^{(R)}$ laminate veneers were significantly influenced by translucency of the coping and shade of abutment teeth. The large value difference of abutment teeth limited the masking ability by laminate veneers.

This study examined the trends of an illustration artist's art marketing widening its area in recent years and proposes a design concept of color cosmetics. Art marketing is a type of culture marketing and means marketing through exhibitions, performances and other artistic activities. Free artistic sensibility expression in which the artistic motif is melted into a product beyond the works of a particular artist, and the product, in turn, can be reflected in the canvas, has attracted attention. The works of illustrators are widening their area into the item in life not canvas. This paper proposes the color cosmetics design that reflect art marketing. The main target who proposed the design concept was trend-oriented and in their early to mid-20s with a strong personality, showing a strong tendency of attracting attention and being recognized. To emphasize the design concept of color cosmetics packaging design, the progressive image of the target class was reflected through brilliant and intense color combination. The cultural value and meaning are provided as the artistic mood becomes a part of life.

The purpose of this study was to identify which combination of zirconia crowns and cements is most similar in color to the maxillary primary incisors by varying the color of zirconia crowns, crown thickness, and shade of cements. Prefabricated zirconia crowns in 3 shades and crowns fabricated using 6 types of zirconia blocks were used in this study. These were filled with A2-shade or translucent-shade resin cement and the $L^*$, $a^*$, and $b^*$ values were calculated using a spectrophotometer. The color differences between the natural teeth and the zirconia crowns were assessed. The shade of the final restoration was more similar to that of the natural teeth using A2-shade than translucent-shade resin cement. Application of A2-shade cement to a 0.5-mm-thick crown fabricated from a smile series 2 zirconia block resulted in the color most similar to that of the natural teeth. A2-shade resin cement is recommended for zirconia crown restoration in anterior primary teeth compared to TR-shade resin cement for more esthetic restoration. Since restorations with Nu-smile zirconia crowns were not esthetically favorable in terms of shade, improvement of the shade characteristics of the product or development of a new kind of zirconia crown is required.

Image mosaicking, which combines several images into one image, is effective for analyzing images and important in various fields of spatial information such as a continuous image map. The crucial processes of the image mosaicking are optimal seamline determination and color correction of mosaicked images. In this study, the overlap regions were determined by SURF (Speeded Up Robust Features) for image matching. Based on the characteristics of the edges extracted by Canny filter, seamline candidates were selected from classified edges with their characteristics, and the edges were connected by using Dijkstra algorithm. In particular, anisotropic filter and image pyramid were applied to extract reliable seamlines. In addition, it was possible to determine seamlines effectively and efficiently by utilizing building and road layers from digital maps. Finally, histogram matching and seamline feathering were performed to improve visual quality of the mosaicked images.

포토닉 의류는 의류에 다양한 광원과 광전달 소재를 적용하여 빛을 발현하는 디지털 기술을 적용하여 의류의 색채를 제어함으로써 착용자의 감성을 시각화할 수 있도록 하는 스마트 의류의 일종이다. 앞서 개발한 포토닉 의류의 중 LED램프와 광섬유의 조합으로 색광을 발현하는 기능은 특별히 RGB 색조합을 통해 의도하는 색채를 다양하게 구현할 수 있다는 특징이 있다. 현재 색채 발현 방법은 Red, Green, Blue의 3가지 색상의 LED의 적절한 조합을 통하여 색채를 발현하는 방식을 가지고 있으나 색체계 상의 기준 색상과 실제 발현되어 육안으로 확인되는 색채의 차이가 있어 의도와는 다른 색채가 나타나 디자이너의 색채 기획의도를 포토닉 의류에 적용하기 힘들며, 기존의 색체계에 의해 생산된 다른 텍스타일 색채와의 컬러 조합에 있어서 필요한 정확한 데이터를 얻기 어렵다. 따라서, 포토닉 의류에 의도하는 색채를 발현하기 위해서는 기존 색상과의 차이점 보정과 효과적인 데이터 베이스 구축이 필요하다. 본 연구에서는 포토닉 의류의 색채에 관한 보다 체계적인 연구를 통해 웹 컬러와 광섬유를 이용한 포토닉 컬러에서의 색채 이미지를 비교, 분석하고 RGB값과 색차값을 통한 차이점 보정을 참고하여 광섬유를 사용하여 제작되는 스마트 포토닉 의류의 제작 시 색채선정 기획에 있어서 기초적인 자료로 활용될 수 있도록 제시하고자 한다.

본 연구에서는 웹 접근성 평가를 위하여 기존의 문서의 배경색과 문자 색 사이의 색 대조 정의에 대한 알고리즘을 조사하고, 비교하였다. 현재까지 나와 있는 색 조합에 대한 색 대비의 정량적 정의는 가독성 측면에서 불완전하며, 사용자에 대한 시험 평가에서도 무시하지 못할 불일치를 드러내고 있다. W3C에서 색 대비 평가 방식으로 추천하는 토론토 대학의 웹 접근성 평가 수정도구인 A-prompt에서 사용하는 알고리즘과 미국 토양조사센터의 토양지도 작성을 위한 색 대비 평가 알고리즘을 비교 대상으로 하여 216개의 웹 안전 색의 조합에 대하여 총 46656개의 비교 평가를 수행하였다. 평가 결과 W3C의 기준은 미국 토양조사센터의 기준보다 대비기준이 너무 엄격하며, 전체 색조합의 94.7%가 부적절한 색 대비를 제공하는 것으로 판정 되었다. 따라서 W3C의 기준은 웹 문서 저작자의 색 선택을 상당할 정도로 제약하며, 적용 기준을 정상인에게도 혼란을 줄 수 있는 기준, 시각적 결함을 가진 사용자에게 혼란을 줄 수 있는 3단계의 기준을 적용하는 것을 제안한다. 추후에는 사용자 평가를 통하여 알고리즘의 타당성을 검증하고, 보완점을 제시할 예정이다.

It is important for designers to be supported with their decision-making on colours which is often based on personal distinction rather than logical dialogue that may lead to confusion within communicating with others. To help these problems and to gain productivity, we would like to propose a way to define colour grouping method. In other words, the purpose of this study is to help to improve the communication and productivity within the design and designers. The grouping was based and inspired by from the studies of Kobayashi, Hideaki Chijiawa, Allis Westgate and Martha Gill. The study of grouping is based on the "tones" of each group, as they seem to reflect a designer s sentimentalism of chosen colours the best. Each of these groups will be named Bright , Pastel ,Deep and Neutral The general concept of each groups are: - Bright: high quality of pixels of primary colour - Pastel: primary colour with white - - Deep: Primary colour with gray or black - Neutral: colours that does not include any of above Each of the colour group has been allocated into Si-Hwa Jung's colour charts and colour prism to visualize the relationships between the colour groups. These four groups and the colours included in them will be broken down to smaller groups in order to make colour palette. This would break the barrier and result in using colours in groups as well as crossover coordination. This study would result in new ways of using colurs for designers designers

People with color vision deficiency (CVD) experience difficulties in discriminating some color combinations and color differences due to the abnormal retinal cone systems. While there exist smartphones with a re-coloring function for CVD, monitors do not provide the re-coloring function. In this paper, we propose a new re-coloring algorithm that adjusts the displayed colors for CVD using a color controller embedded in the monitor. The proposed algorithm converts the hue and saturation in HSV color space, according to the type and strength of the color deficiency. The results of the performance evaluation with a certain number of people with CVD show that the proposed system can convert colors imperceptible into perceptible.
