This study was done with a goal to observe changes of color emotions according to time flow and light changes as well as to study its moaning of color experience of natural scene to modern city dwellers with artificial surroundings. Individuals develop various feelings after seeing a color, but there is sometimes a common feeling raised among these various feelings. This study aims to investigate the influence of natural colors of surroundings on the emotions of human beings. First of all, we tried to discover how feelings change after a person is reminded of a color through an experience (recognition) of a natural color. Second, differences in feelings resulting from color perception are analyzed after time passes (sunrise, daytime, and sunset) and the colors of natural surroundings change accordingly. Survey was done in the period of $Jul.8^{th}$ to $10^{th}$, 2005 with 100 people (55 male and 45 female) in various professions and various ages between twenties to forties as respondent.

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 study is a basic research to suggest user-centered healthcare environmental color, which aims to analyze tendency of color consciousness and preference depending on the user characteristics (generation, gender, residential area, and environment). For this purpose, this study constructed an analysis tool through the literature review with regard to environmental color of healthcare facility and influential factors of color preference. Besides, an online survey regarding general usage and satisfaction, health related color consciousness, and color preference tendency of healthcare facility was conducted targeting from 20s to 60s, total 1,500 persons. The results of this study are as follows: (1) The usage and satisfaction of healthcare facilities were higher for older generation and accessible urban area. (2) The respondents were aware that color and health are related, recognizing 'green' as healthy and stress relieving color. Besides, 'natural' and 'clear' was the highest in health related color image. 'Light' which relates to vitality was high as well for older generation. (3) In the color preference tendency survey, hue PB was generally the most highly preferred, in details, younger generation preferred B and R while older generation preferred G. The survey also showed high value and chroma were preferred, while female and younger generation preferred high value of 9.0 and low chroma close to achromatic color, which presented older generation preferred vivid color.

After the "Landscaping Law" was enacted in 2007 Korea, national and local governments has been responding swiftly by seeking various methods. Seoul Metropolitan City and other municipalities have established "Seoul Coloring and Systematization" project, which analyzes and extracts the humanities, humanities and natural environments in 2007 as an opportunity to recognize the importance of environmental color. However, it is necessary to slightly supplement the color scheme created by the observer's concept. In this way, you have to find the color of the environment in a city where real life takes place. The city's environmental color has the concept of "walking" as the basic human behavior. Because the average speed is 4km, it differs from that of a vehicle that travels more than 60km per hour. Also, most of the frontage zone is used except for special cases. Therefore the characteristics of the environmental color and frontage zone on the road side were concluded in this paper as Single Type, Connection Type, and Extension Type. In addition, the principle of environmental color of city was established by the change of texture according to space of time and the characteristics of urban scale, and new media characteristics were found in various interactions. The results of this study suggest an environmental coloring strategy for workability such as hue continuity, hue harmonization and integrated design.

Recently many environmental researcher are concerned about the ecological environment and the issue of environmental pollution in cave. In this paper we discuss about air pollution, water pollution, state of water quality, ecological environment and situation of environmental public damage in cave The concerning of air pollution in cave is mainly to the type of secondary contamination, which much is developed in various fields recently. The natural water in the most of cave is no problems but ground water has slitting with natural water during much raining period. The state of water quality is gradually contaminated with artificial environmental pollution, that is, the contents of kinds of Aluminum, Nickel, Copper, Zinc and Calcium are higher than before. On the other hand it is very important things to keep the control of constant temperature, darkness and humidity in cave. The contamination by lamp flora and even black colored contamination are appeared nowadays. The ecological environment in cave destructed by growing of mi coorganism. In fact the internal of cave is shielded with the state of climate of cave external but the environment of internal cave is contaminated, because blowing from external climate state. In addition to environmental pollution caused by carbon dioxide and body temperature of tourists. By the way eco-examination of cave is black color public damage, green color one and white color one has been discovered, so we need to have the situation of demand of environmental reservation alternatives.

Hair coloring before the 1980s was mostly to hide white hair by dying in black. With the introduction of color TV, however, the size of the coloring market has been expanding. Nowadays, artificial synthetic dyes are widely used, which, though advantageous in many points, have problems such as harmful effects on the human body, carcinogenesis, environmental contamination and damage on hair. On the contrary, natural vegetables obtained from Curcuma Longa L., A. catechu, polygonum indigo, henna, etc. are little harmful to hair or the skin of the head and cause few environmental problems. In addition, as they are natural materials collected from nature, they are considered positively by consumers. Thus the present study started from the necessity of research on the convenient use of environment?friendly and side-effect-free natural dyes, coloring technology for reproducing original color, the improvement of adhesion rate, etc. From the present research were obtained yellow color from Curcuma Longa L., brown from A. catechu, blue from polygonum indigo and orange from henna. It is expected that, based on materials from previous researches, there may be more researches on the use of natural dyes as hair colors.

The purpose of this study is to provide the methods of harmony in color combination of environmental color for apartment in order to improve the image of the urban landscape. For this study, apartment in Iksan City was selected is a sample and twenty two apartments were analyzed. This framework of this study is A. Hard and L. Sivik's color combination model based on Natural Color System. This study examines various theories on environmental color perception and new approaches to color aesthetics, and tries to present perceptual properties that can be applied to environmental color design First, the principle of color harmony feeling in based on nuance and tone. Therefore, to control brightness and chromaticness with are related with nuance is important in color combination. Second, the aesthetic experience in color preception can be defined as a combined effect of similarities and differences of color attributes. Third, color harmony theory is one of the areas that can be benefit a great deal from and interdisciplinary approach, add empirical study such as this can be used as a basis for environmental color design and evaluation.

For building an urban image, various elements such as symbolic building, ethnic characteristics, historical background, natural environment, and diverse cultural elements can influence on it. Many cities in developed countries are showing their unique urban image reflecting their own culture, history, and aesthetic tastes. Especially color, one of the major design elements, has greater impact than other visual factors to form an urban characteristic. Despite the long history and cultural background, Seoul as a capital city of Korea does not show an unique city image with the perspective of color. Recently, Seoul has been designated as '2010 World Design Capital' and implements various urban design projects. As a leading city of design, Seoul is trying to make its urban identity through the own symbolic environment color. The purpose of this study is to find an environmental color scheme for developing a desirable urban design through several cases of foreign countries. For the purpose, Paris, London, Amsterdam, and Tokyo were selected as case cities. Each of the cities showed their own cultural characteristics and made their unique urban image by appropriate usage of their natural environment, symbolic building, emblem of country, and so on. We need to consider these successful cases to build up the image of Seoul.

To evaluate the Hwangsu spring as natural mordants effect on dyeing. The natural mordants effect of Hwangsu spring were analyzed by pH, temperature, trace elements, organic matter and color fastness. Hwangsu spring having pH 2.42 and $14.4^{\circ}C$ was harvested at the end of September, in Yeongcheon (Gyeongbuk Province, Korea) and left on a $0^{\circ}C$ and $25^{\circ}C$ before use. Hwangsu spring during storage at $25^{\circ}C$ turned brown by photochemical reaction. The Result of ICP analysis, it contained Fe(414.9 ppm), Al(88.9 ppm), Mn(4.9 ppm) and observed character by water analysis. Dyeing and post-mordant procedure; Cotton(KS K 0905) were dyed with clove powder for 30 min at $70^{\circ}C$. Hwangsu spring, Aluminium Sulfate $14-18H_20(Al_2(SO_4)_3{\cdot}14-18H_2O)$, Iron Sulfate Heptahydrate($FeSO_4{\cdot}7H_2O$) were used by post mordant at the same ratio. The dyed fabrics were treated with 20% each mordant solution at $25^{\circ}C$ for 10min. Comparison with a reproduced chemical mordant, the K/S values of cotton fabrics dyed with Hwangsu sping were increased.
