With the advent of the Fourth Industrial Revolution, people need healing. Research in neuroarchitecture shows that people feel happy and stable when working with nature, and patients heal quickly. Therefore, This study aims to quantitatively analyze the colors that help psychological healing in the painting images depicting nature by setting 'Natural Colors' of Biophilic Design as the subject of research. So the purpose of this study was to measure Biophilic Color and to develop Biophilic Color Palette. We extracted Biophilic colors using Impressionist Monet's Landscape painting. After extracting colors using Photoshop Color Picker, we converted RGB color code to NCS color code and Munsell color code. The results of this study were as follows; The ratio of Y was high in the GY-series and YR-series. This is due to the characteristic of impressionism that expresses the change of color by light in close relationship with light. Y is universally considered to be pleasant, representing happiness, sunshine and optimism. Therefore, it is possible to create an environment that helps psychological healing by utilizing the Y-series color palette. Average Blackness was 28. Average Chromaticness was 34.61. The significance of this study is to propose a biophilic color palette that is useful for psychological healing by quantifying the color code of biophilic colors depicted and expressed with adjective images and idiomatic color names. Quantitative and empirical studies on healing colors are needed continuously and should be actively utilized in healing environment planning.

Color image quantization is a process of selecting a set of colors to display an image with some representative colors without noticeable perceived difference. It is very important in many applications to display a true color image in a low cost color monitor or printer. the basic problem is how to display 224 colors with 256 or less colors, called color palette. In this paper, we propose an algorithm to design the 256 or less size color palette by using spatial maskin geffect of HVS and subjective distortion measure weighted by color palette by using spatial masking effect of HVS and subjective distortion measure weighted by color activity in 4*4 local region in any color image. The proposed algorithm consists of octal prequantization and subdivision quantization processing step using the distortion measure and modified Otsu's between class variance maximization method. The experimental results show that the proposed algorithm has higher visual quality and needs less consuming time than conventional algorithms.

현대인은 시각, 제품, 환경 디자인뿐 아니라 웹 콘텐츠, 애니메이션, 영상자료 등의 홍수 속에서 생활하고 있다. 그러므로 현대의 소비자는 그 어느 때 보다도 많은 선택권을 가지고 있으며 모든 디자인 결과물은 소비자에게 다양성을 제공할 수 있어야 한다. 우리는 디자인의 발전과 더불어 색채를 통한 새로운 감성을 개발함으로써 소비자에게 한 발 더 가까이 접근해야 한다. 그리고 새로운 감성을 창출하여 소비자에게 제안해야 한다. 본 MCC 팔레트는 디자인 할 떠 보다 정확한 감성을 적용하여 개인적인 편견을 없애고, 사용자에게 디자인 의도를 정확하게 호소하기 위한 것이다. MCC 팔레트는 한국적인 정거와 감성언어를 연구하고, 문헌적인 자료와 사진자료를 통해 감성 형용사를 수집하였다. 그리고 수집된 형용사를 균등하게 배분하였으며, 배분된 형용사를 각각 감성의 분야별로 정리하여 체계를 수집하였다. 그리고 각각 형용사별로 3색, 4색 배색을 하고 이들의 결과를 색채 전문가와 디자이너에게 설문 및 자문을 통하여 팔레트를 구성하였다. 그 결과 보다 실용성이 높은 색채 팔레트를 완성하였다. 완성된 배색은 웹상의 www.mcdri.net에서 운영되고 있으며, 또한 winders로 프로그램 되어 CD-ROM형 소프트웨어로 개발하였다. 인구결과로 만들어진 MCC 팔레트는 감성 자료 검색 데이터베이스를 구축함으로써 개발 후 실질적으로 적용이 가능하며, 각 매체별 색채오차 해소, 색채 배색의 검색을 통한 아이디어 개발, 사용층 및 사용대상에 대한 체계적인 접근을 용이하게 한다. 즉 산업체 활성화, 실무 사용자의 편의 도모, 디자인 교육 활성화를 위한 정보제공 등 산업계 및 교육계에 많은 도움이 될 것이다.

Many image display devices allow only a limited number of colors to be simultaneously displayed. in disphaying of natural color image using color palette, it is necessary to construct an optimal color palette and the optimal mapping of each pixed of the original image to a color from the palette. In this paper, we proposed the clustering algorithm using local region block centered one color cluster in the prequantized 3-D histogram. Cluster pairs which have the least distortion error are merged by considering distortion measure. The clustering process is continued until to obtain the desired number of colors. The same as the clustering process, original color value. The proposed algorithm incroporated with a spatial activity weighting value which is reflected sensitivity of HVS quantization errors in smoothing region. This method produces high quality display images and considerably reduces computation time.

New methods for both color palette design and dithering based on human visual system (HVS) characteristics are proposed. Color quantization for palette design uses the relative visual sensitivity and spatial masking effect of HVS. The dithering operation for printing uses nonlinear quantization, which considers the overlapping phenomena among neighbor printing dots, and then a modified dot-diffusion algorithm is followed to compensate the degradation produced in the quantization process. The proposed techniques can produce high quality image in the low-bit color devices.

저 사양 HMD(Head Mounted Display)를 사용하는 가강 환경 네비게이션 시스템은 true-color 이미지를 제한 된 색으로 표현 할 때 이미지를 양자화 해야 한다. 그러한 시스템은 고정된 팔래트를 이용하여 전체적으로 이미지를 양자화하고 사용자에게 주로 이미지의 일부분(시선영역)을 보여준다. 인간의 눈은 시선영역의 색변화에 민감하고 HMD를 통해 이미지의 일부분만을 보기 때문에 시선영역의 색만을 고려하여 동적으로 팔래트를 생성하고 이를 이용하여 이미지를 양자화 한다면 사용자는 가상 환경을 보다 생동감 있게 느낄 수 있다. 본 논문에서는 사용자가 가상환경을 보다 생동감 있게 느끼게 하기 위한 동적 팔래트 생성 방법을 제안한다.

This study proposed a color scheme that is harmonious with the working environment of industrial sites using Birren's color harmony theory for color planning. To apply the Birren's color harmony theory to working clothes, the basic colors were chosen, and six of the eight harmony formulas of Birren excluding achromatic colors (white + grey + black) and solid color harmony (solid colors + white + black) were used to form a palette for each case. For the basic colors, the color chips of four dominant colors (yellow-green, sky-blue, blue, and violet), which were chosen from a field survey for preferences in the first step, and the production of materials in the second step were collected through the PANTONE color chips. The selected color chips were PANTONE 13-0550 TPX, PANTONE 15-4105 TPX, PANTONE 18-3949 TPX, and PANTONE 19-3720 TPX. These color chips were scanned and their RGB values were extracted through Photoshop CS. Then the colors were arranged in accordance with the Birren's color harmony formulas (Color+Tint+White, Color+Shade+Black, Tint+Tone+Shade, Shade+Tone+Black, Shade+Tone+White, and Tint+Shade+Tone+Gray). In addition, the proposed palette color schemes were applied through Birren's color harmony formulas using Texpro V 10.1 textile to the schematization of working clothes that were designed in the previous study. Palette formation in line with Birren's color harmony formulas provided scientific color arrangement results. Visually presenting the color scheme of working clothes will help the color selection of working clothes in tune with the circumstances of industrial sites.

The purpose of the study was to determine if an abstract color palette was representative of a color scheme of interior environment by which the meaning of colcor could be determined. An abstract color palette was developed by the researchers to show contrast, overlapping, and adjacencies as they might actually appear in an interior environment. Six pictures and six color palettes were used to test the meaning of color. The questionnaire consisted of 21 words to describe the color of interior environment. The sample consisted of 73 undergraduate students of varied majors. A factor analysis was used to identify the structure of color meaning. Five factors; emotional factor, factor of unity, spatial quality factor, factor of complexity, and social evaluation factor were identified. A t-test was used to analyze the difference in responses to the descriptor words for the pictures and palettes. It was found that in 14 of 21 descriptor, there was no significant difference between evaluation of color meaning for the pictures and palettes in 50% or more of the cases.
