In this study, basic physical properties and color development of the black concrete depending on CASB-SP dosages are investigated. According to results, It showed that the slump and air contents of the concrete containing CASB-SP meet all requirements of concrete except when CASB-SP 5.0 % is used. It also showed that the more the CASB-SP is used, the higher the compressive strength becomes. On the other hand, It is found that if the CASB-SP 5.0 % is used, the compressive strength was reduced as the more CASB-SP 5 % is used. In terms of color, it was found out that the more CASB-SP is used, the darker the black becomes.

In the construction of a white LED, the region of the red emission is a very important factor. Red light emitting materials play an important role in improving the color rendering index of commercial lighting. These materials also increase the color gamut of display products. Therefore, the development of novel phosphors with red emission and the study of color tuning are actively underway to improve product quality. In the present study, heuristic algorithms were used to search for phosphors capable of increasing the color rendering index and color gamut. Using a heuristic algorithm, the phosphors that were identified were $SrGe_4O_9:Mn^{4+}$ and $BaGe_4O_9:Mn^{4+}$. Emission spectra study confirmed that these phosphors emit light in the deep red wavelength region, which can fulfill the requirement for the improvement in color rendering index and color gamut for a white LED.

In South Korea, with the advancement of the 'Port' project, the regeneration industry adapted to the modern economic development has been promoted, leading to construction around the port was also redefined. Therefore, through regeneration, the problem of image construction of buildings around the port has been re-examined, in which color is an important content of image construction. In this study, the exterior walls of abandoned factory buildings in the port area of Bongnaedong, Pusan were selected as the color research object and evaluated according to the characteristics of the regenerated factory buildings combined with the building color function. Technically, KSCP color analysis system is used for color analysis. In this way, the color plan for the exterior walls of the factory buildings is proposed to visually enhance the image of abandoned factory buildings and attract more attention, thus driving the regional economic development. The results of this study show that in order to adapt to the regional, industrial and commercial characteristics of the regenerated port space, the color hue, lightness, chroma and use area of the building can be changed to enhance the aesthetic value and enhance the inductivity and security.

The color harmony in video was no way to know for giving pleasure. By identifying these color harmony, it gives order, clarity, similarity, contrast, etc. Therefore, to identify the color balance is very important. Color Harmony identify the color is whether the harmony by color harmony theory of Munsell, Ostwald, Firren, Moon & Spenser, Itten, Chevreul, and Judd etc. One of these methods, we identify color harmonies of 2 colors, 3 colors, 4 colors, 5 colors and 6 colors using Itten's color balance. Identification is using by Canny edge extraction, labeling and clustering, and color extraction and harmony etc. By identifying this color harmonies, we have laid the foundation of emotional database construction and emotional recognition.

Biophilic design gives human beings positive and valuable experiences in nature. The experience in nature in the architectural environment is mainly symbolic and metaphorical, and is based on visual sensations such as color, form, and image. Recently, modern people living in a modern and simple style indoor space have a desire to pursue visual stimuli for interest or pleasure. This desire can be satisfied through color, lighting, and finishing plan. Therefore, the purpose of this study is to propose a biophilic design color palette based on the empirical characteristics and properties of biophilic design. The methods used in this study are as follows. First, the biophilic design factors and natural landscape preference criteria are examined. Second, based on the review results, natural landscape images are selected and color information for each biophilic design element is extracted according to the vertical and horizontal directions. Third, color information is converted to NCS color code and palette range and hue range are derived through the analysis of ratio and average values. Finally, based on the analysis results, biophilic design color palette is proposed for each element. The results of this study might be useful as basic data in establishing biophilic design strategies and applying them to architecture and interior construction.

Color inverse halftoning is the transformation of a color-halftone image to a continuous-tone color image that is more natural in human vision. In this paper, we propose a new smoothing mask that can remove halftone patterns in channel effectively and we apply it to color inverse halftoning. The proposed smoothing mask can make channel images more smooth and natural in human vision than traditional ones. Its characteristic can be adapted automatically according to the various color halftone images. We analyze the result images in various aspects through experiments. Experimental results show that the mask is useful for color inverse halftoning. It can be applied to field of multimedia application, such as desktop publishing, color facsimile and digital library construction.

Until 1960, the major housing type of rural area in Korea was traditional wooden frame building, which was made of natural materials. In the course of modernization and New Village Movement, most of traditional houses have been renovated focusing on changing roof material of rice straw into slate, keeping existing main wooden structure. And then from around 1980, by economical development the new houses have been constructed. On these three phases of traditional type, remodeling type and new construction type, the natural materials of housing facade as wood, soil, stone and plant changed into artificial materials as cement, chemical material and paint. At the same time the exterior color of housing also have been changed and varied. The purpose of this thesis is to find out the changing aspect of exterior color by comparing remodeled and new constructed housing with of traditional housing. The exterior color of one hundred and fifty seven houses were surveyed and the three color attributes of each part of facade, as roof, wall and window, were analyzed and compared. In case of traditional houses, 98.3% of color are concentrated on the warm color of Y and YR on HUE scale, and 88% of their color are low Chroma. And Value of their color has been varied and spreaded from low to high Value scale. From traditional types to remodeled and new constructed houses, the concentration ratio of warm color on Hue scale reduced from 98.3% to 68.7% and ratio of low Chroma was also changed from 88% to 73.2% and the ratio of low Value color reduced from 51.9% to 29.7%. The exterior color of houses in rural area varied on Hue, and the more saturated colors were used and they became brighter compared with color of traditional houses. It is expected that the results of this study can be used for basic data of exterior color planning and improvement into harmonized color with natural environment.
