Objective: The objective of this study is to evaluate affection on how users perceive colors viewed from an automotive visual display according to cultural and radical differences including North America, Europe, and Southeast Asia. This study especially aims to identify effects of the variation of tone and chroma of representative color groups by analyzing affection differences depending on cultural and racial differences targeting the colors constituted through variation of tone and chroma, centered on representative colors. Background: The colors of the menu, information display or background viewed through an automotive visual display are an important factor stimulating consumer's affection, and therefore an effort to express the vehicle's brand and product image through colors is made. The studies on colors focus only on the research on unique characteristics of colors, but an affective approach lacks according to cultural and racial differences on colors considering tone and chroma variation within a color from the currently used automotive visual displays. Method: To grasp the visual affection felt by users, this study extracted affective adjectives related with colors through existing literature and a dictionary for adjectives, and presented human affection dimensions on colors through evaluation of various colors. Prior to carrying out affection evaluation, the basic light sources, red (R), green (G), and blue (B) constituting the colors used for automotive visual displays were defined as a representative color group, respectively. When colors in a color group are constituted, the evaluation target of each color group consisted of the colors considering the variation of tone and chroma by changing color sense through RGB values of the remaining two light sources. And then, this study carried out affection evaluation on the constituted colors targeting the subjects with cultural and racial differences. Results: As a result of evaluating the constituted colors with representative affections, there were statistically significant differences between the groups having cultural and racial differences. As a result of S-N-K post-hoc analysis on the colors showing significant differences, North America and Europe were classified as heterogeneous groups. In some cases, Korea was classified as the homogeneous group with North America, but Korea was mainly classified as the homogenous group with Europe. Conclusion: The representative affections on colors from an automotive visual display was drawn as three affective dimensions: passionate, neat, and masculine. Based on these, the affection of Korea and Europe on the constituted colors showed significant differences from that of North America, as a result of affection evaluation on the constituted colors viewed through the visual display by reflecting cultural and racial factors. Regarding representative color groups, bigger cultural and racial differences were revealed in terms of affection on red and green colors than on blue color, and variation of affection was the biggest in the red color. Application: This study analyzed correlations of affection considering the colors constituted through variation of tone and chroma, and the culture and race in the representative color groups constituting a visual display. The results of this study are predicted to be utilized in coordination and selection of colors viewed from an automotive visual display taking into account culture and race.

This study analyzes the characteristics of the motifs and colors in flower and bird paintings which contain and present Korea's unique aesthetics based on its richest data among all other types of Korean folk paintings. With a theoretical exploration of folk paintings and an analysis of the motifs and colors, textile design with an aim to present highly valued korean modern fashion design was developed. Two hundred and seventy flower and bird paintings were selected from relevant materials, resulting in an extraction of 5,068 colors. A palette of representative colors was made based on densely distributed hues and tones. The research can be summarized as follows: Flower and bird paintings contain flowers, birds, trees and animals and the motifs in the paintings stand for spirituality, philosophies from different times and other symbols of our nation. Each of the motifs in these paintings is a prayer for good luck, especially conjugal harmony and fecundity to bring about happiness and richness. Colors in flower and bird paintings are characteristic of the order: YR(25.5%)>R(19.2%)>Y(10.6%)>PB(9.2%)>G(7.9%), with low-chromatic YR and highly bright R taking up a larger percent. The order of tones is: d(13.5%)>dk (10.5%)>s(10.4%)>dkg(10.0%)>sf(9.1%)and the tone is dark in general. YR, taking up the largest percent, was dull, light, and soft. As for the achromatic colors, the order is: W(5.2%)>Gy(1.9%)>Bk(0.7%). Based on the above analyzed color data, those colors which were high in their hue and tone were extracted to present representative colors. In this way, representative colors like yellow, yellowish red, red, green, and purplish blue were extracted. This was the basis to present motifs and colors originating from subjects of folk paintings in various patterns using Illustrator CS6, to create modern fashion design.

This paper proposes color databases that can be used for various purposes for people with a color vision deficiency (CVD). The purpose of this paper is to group colors within the sRGB gamut into the CIE $L^*a^*b^*$ color space using the Brettel algorithm to simulate the representative colors of each group into colors visible to people with a CVD, and to establish a confusion line database by comparing colors that might cause confusion for people with different types of color vision deficiency. The validity of the established confusion lines were verified by using an Ishihara chart. The different colors that confuse those with a CVD in an Ishihara chart are located in the same confusion line database for both protanopia and deutanopia. Instead of the 3D RGB color space, we have grouped confusion colors to the CIE $L^*a^*b^*$ space coordinates in a more distinctive and intuitive manner, and can establish a database of colors that can be perceived by people with a CVD more accurately. Editor - Highlight - Do these changes reflect the intended meaning? If not, please rephrase as intended.

본 논문에서는 칼라와 에지 정보를 이용한 내용기반 영상검색 기법을 제안하였다. 기존의 RGB 공간 정보를 이용하기 보다는, 시각적 인식에 보다 중점을 둔 HSI칼라 공간에서 고찰하였다. 비슷한 류의 색을 대표색으로 통합 표현하여, 개선된 칼라 정보 이용법을 본 연구에서 제안하였다. 또한 칼라 정보만을 이용했을 때의 시스템 성능상의 결점을 보완하기 위하여, 효율적인 에지 디텍션 기법을 함께 사용하였다. 칼라와 에지 기법을 통합함에 있어서, 각각의 기법에 적절한 가중치를 배분함으로써 시스템 성능을 실험적으로 향상시켰다.
