This study aims at suggesting the applicability of color combination based upon the characteristics of environmental color perception and the nuance concept of Natural Color System(NCS). The results are summarized below: First, NCS is a scientific coloring system in consideration of the relevance between people, light and environment, to be based on a phenomenological point of view. NCS can be called a psychometric model reflecting our natural color sense. Second, the color triangle established by NCS is one of the methods of expression based on the human visual mechanism, which is classified by two attributes of hue and nuance, not by the three color attributes of hue, lightness and saturation. The nuance concept of NCS implies the impression, atmosphere and tone that are perceived in colors, which are related to lightness and saturation. Accordingly, this paper suggests that the coloring arrangement emphasizing nuance and tone is more useful than hue in color planning. Third, aesthetic impression in environmental color perception is inclusive of instantly perceptive nuance, which is connected with affordance. The affordance is revealed by the different relation of similarity. In this regard, a strong relationship is noticed between color combination and the sense of pleasantness. The hypothesis regarding the complementation and similarity of contrasting nature is judged to provide observers with aesthetic order. Finally, this paper also suggests four harmonizing methods in the NCS color triangle based upon equal blackness, equal whiteness, equal chromaticness and same nuance. At the same time, opposition and a different concept of hue, lightness and lightness are combined complementarily with the nuance value to suggest patterns of color combination.

This thesis aimed to reduce the differences of hair color when hair coloring, so it researched the differences & changes in hair color before shampoo v.s. after shampoo and dry on different heat processes when acid hair color dyeing. Five hair color dyes (Y, R, B, G, Br) manufactured by two different corporations were used. The acid hair color dyes were tinted on black and bleached hair pieces subjected to 3 different heat process; 1. Normal Temperature($25^{\circ}C$, 30min.) / 2. Heating($40^{\circ}C$, 15min.)+Normal Temperature($25^{\circ}C$, 15min.) / 3. Heating($40^{\circ}C$, 30min.). Color numbers were divided by NCS value, chroma, and hue. Statistical averages were derived and t-test was conducted using SPSS V12. Hair color differences and changes were drawn on an NCS chart using Photo Shop PS. The conclu is; If acid hair colorings are separated by a heating process, hair value & chroma change before shampoo vs. after shampoo & dry regardless of the color of hair and the heat process. Hue is not changed or shifted counter clockwise NCS color circle, but some exceptions, and it's the same when the total heat process results are combined. Black hair's value shifted downward and chroma left, and hue stayed either neutral or one color or it shifted counter clockwise on NCS color circle. Bleached hair's value shifted upward and chroma right, and hue stayed one color or shifted counter clockwise, but some exceptions. And it can be shown on NCS chart.

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.

A new fastness formula based on CIEDE2000 color-difference formula is developed by B. Rigg and his coworkers. It is very simple to calculate fastness grade for color change than ISO 105-A05 fastness formula based on CIELAB color-difference formula. Sample pair sets which cover a wide range color space were accumulated from NCS(Natural Color System) color book. For those sample pair sets, visual measurement experiment and instrument measurement experiment of fastness grade were carried out and each performance of ISO 105-A02 fastness formula and newly developed fastness formula was compared through degree of agreement for visual measurement result. Newly developed fastness formula indicated improved performance for measuring fastness grade but current ISO fastness formula for assessing change in color, ISO 105-A05, was confirmed that it's performance is inadequate to measure fastness grade. Then fastness formulae were examined more closely according to particular color spaces and the correlation of hue, lightness and chrom for measuring fastness grade was also considered in this study.

As the international competitive landscape deepens, the need to understand foreign cultures and establish effective strategies is increasing. At the beginning of the 20th century, Cartier actively developed exotic designs to secure international competitiveness; theses designs have also been used as design prototypes for Cartier in modern times. The purpose of this study is to analyze the color characteristics and types of exotic designs in the early 20th century, which was a turning point in Cartier's design. After studying the literature, a total of 248 exotic designs were presented in Cartier catalogs. This study also selected overseas monographs from the early 20th century, and their design types were classified and color analysis was performed based on the Natural Color System(NCS). Cartier's exotic designs cover wide range of styles, such as Chinese, Japanese, Persian, Indian and Egyptian styles. Multicolor, primary colors, and contrast are all strongly expressed. 97% of designs contained multiple colors, with at least two colors and maximum of six colors. The most frequently used colors are red, green, and blue, which means that only 9% of the designs do not contain the three colors, showing a high preference for theses three colors. In addition, color combinations of red and green, red and blue, or all three colors are used to show high contrast and utilize complementary colors, or near complementary colors, for coloration. This study is meaningful in that it analyzes the color characteristics of Cartier's exotic designs and translates them into practical data for establishing the color strategies of companies in the global market.

A new fastness formula based on the CIEDE2000 color-difference formula was developed by B. Rigg and his coworkers. It is much simpler to calculate the staining fastness grade than the ISO 105-A04 fastness formula based on the CIELAB color-difference formula. Sample pair sets, which cover a wide color space range were accumulated from the NCS(Natural Color System) color book. for those sample pair sets, a visual measurement experiment and an instrumental measurement experiment of fastness grade were carried out. Each performance of the ISO 105-A43 fastness formula and newly developed fastness formula was compared through degree of agreement for visual measurement results. The newly developed fastness formula indicated improved performance for measuring fastness grade as it was confirmed that the performance of the current ISO fastness formula ISO 105-A04 for assessing staining, was inadequate for measuring fastness grade. Then the fastness formulae were examined more closely according to the particular color spaces and the correlation of hue, lightness and chroma for measuring staining fastness grade was also considered to recommend more improved fastness formula. By modifying the weighting functions of CIEDE2000, which is a basis of new fastness formula developed by B. Rigg, a modified fastness formula is proposed in this study.

과학기술이 발달한 현대에 살고 있는 우리는 모두 ‘에너지’로 인해 편리한 생활을 영위하고 있다. 우리나라는 자원빈국으로 에너지원의 대부분을 해외에서 수입하고 있는 실정이며 계속되는 경제 성장과 국민 생활수준의 향상으로 에너지 소비는 더욱 증가하는 추세이다. 원자력은 우리나라처럼 에너지 부존자원이 빈약하고 에너지 수입 의존도가 높은 나라에서는 필수적인 에너지 자립형 대체에너지라고 한다. 하지만 원자력 발전이 위험 시설이라는 부정적인 인식과 방사능 처리 시설에 대한 불신 문제가 이슈화되면서 원자력 발전에 대한 대국민 교육, 홍보가 절실히 요구되고 있다. 이러한 문제를 환경 색채계획의 관점인 친인간, 친환경 색채계획을 목표로 접근하였으며 이를 통해 원자력에 대한 부정적 이미지를 최소화하고 친근하고 자연스러운 이미지를 부각시키며 대 국민 신뢰성 향상 및 청정 이미지 구축이 본 연구의 목표이다. 이를 위하여 일본의 원자력 발전소와 국내 발전소의 사례를 조사, 분석하고 발전소가 건설될 대상지를 방문하여 자연환경, 현황분석을 통하여 구체적인 색을 추출하였으며 지역 주민의 참여를 유도하고자 선물조사를 실시하여 색채계획에 반영하였다. 원자력 발전소의 환경 친화적 이미지구현을 통해 발전소의 안정성 및 친근한 발전소 이미지를 구축하며 원자력 발전에 대한 일반 국민들의 부정적인 인식을 계도하는데 적극적인 홍보 전략 및 수단으로 외관 환경색채계획을 시도하며 이를 통해 원전의 새로운 이미지 창출에 기여할 것으로 기대된다.
