The purpose of this study was to examine the visual evaluation of image according to the style, hue, value, and chroma of the male clothing and the preference of image. A quasi-experimental method was used for this study. The first factorial design was the $2{\times}3{\times}2{\times}2$ (style of upper clothes ${\times}$ hue ${\times}$ chroma ${\times}$ color of trousers), and the second factorial design was the $2{\times}3{\times}2$ (style of upper clothes ${\times}$ value ${\times}$ color of trousers). The styles of upper clothes were a soutien collar casual jacket and a polo shirt. The subjects were 509 female college students living in Seoul. Factor analysis showed five image categories of men's clothing: initiative, dignity, politeness, activity, and mildness. Yellow was evaluated as having the highest initiative and activity. Blue was shown to have lower mildness than red and yellow. The high saturated chroma was perceived to be higher initiative and activity than low chroma. The shirts were evaluated higher in activity and mildness than the casual jackets were. The beige pants were perceived to be higher in dignity and mildness than the dark blue pants. The high chroma jackets were perceived to be higher in both initiative and activity than the low chroma jackets. The navy blue pants with the upper clothes in low chroma blue were perceived to be higher in politeness than with the upper clothes in low chroma red or yellow. The low value clothes were perceived to be higher in both initiative and dignity.

The objective of this study was to find in what color Korean handmade paper(Hanji) is dyed when it is dyed with a pigment extracted from mugworts using different kinds of mordant, and how the paper is discolored and variety of strength under the condition of accelerated aging test. The results of this experiment are as follows. Among mugwort mordants, only ferrous sulfate mordant produced unique khaki color with a slightly lower degree of discoloration, so it is considered to be applicable in dyeing Korean paper. Bright yellow and light green colors were obtained using mugwort but their chroma was too low for actual use. With regard to water used, colors obtained using underground water had high chroma, but when distilled water was used paper was colored in useless light green. Mordant was found to lower the strength of Korean handmade paper, and the lowering of strength was even more serious under the condition of forced deterioration.

Natural red colorants were extracted from Phytolacca americana Linne by using 50% ethanol solution at room temperature for 12 hours. The colorant components were partially purified as yellow and deep red colorants by thin layer chromatography. Natural red colorants were consisted of major water-soluble red colorant, having maximum absorbance at 538nm and alcohol-soluble yellow colorant, having maximum absorbance at 664nm. Concentration of red colorants were calibrated by the equation of dye(mg/ml) $A_{538nm}\times{1.284}$. Red colorants were changed to yellow at extreme alkali pH and repaired 55% color intensity by neutralization of pH and stabled below $55^\circ{C}$. Dyeability of red colorants against wool fabrics was mainly operated by red pigment having 538nm absorbance without big color differences. Below $55^\circ{C}$, color differences $(\Delta{E}^*_{ab})$ were not changed in spite of big difference of chroma$(c^*)$, having higher scores at higher temperature. The effect of mordants were not drastically changed parameters of color difference without copper ion. Citric acid was big changes of color difference$(\Delta{E}^*_{ab})$ in spite of similar chroma$(c^*)$ values. From these experimental results, red colorants from Phytolacca americana Linne is available for wool fabric dyeing.

The purpose of this study is to analyze the colors in the school libraries and identify the images of adjectives derived from the colors. This study investigated the hue (basic color), value (brightness) and chroma (color intensity) in the school libraries through KSCA program. It analyzed 15 school libraries from elementary schools to high schools. Furthermore, with the aids of I.R.I Adjective Image Scale, the adjective images of the colors could be identified. The results are as follows: In the elementary school libraries, the hue was used in the order of YR (yellow red), N (neutral), and Y (yellow), while in the order of YR (yellow red), N (neutral), and R (red) in the middle school libraries. All the school libraries had medium brightness on average, whereas the colors had a low chroma. As for the adjective images of the colors, the adjective 'gentle' has appeared the most in every school library. The school libraries have similar colors and adjective images for all levels, not presenting any particular differences in the colors of every interior space arrangement.

The purpose of this study is to research the similarity and difference of color application in the culture of Korea and Japan. The subject of this research is the costume color of Changgeuk and Kabuki. This survey analyzes Munsell's 3 attributes(Hue, Value, Chroma), tone, and 3D color analysis by extracted color data. And representative color according to Obangsaek is proposed. The results of this study are as follows: 1. High chroma red in Kabuki costume is more used as symbolic color(passion and luxurious) in order to show character's personality than that in Changguek costume. 2. Low chroma YR color(no-dyeing color) in Changgeuk costume much more used because of Korean white robe preference and eco-friendly thinking. But high chroma yellow is restrictive color for symbolic color of emperor in Korea and Japan. 3. Blue is most frequently used in both costumes because blue is encouraging color by the theory of exponents of the five elements doctrine. 4. White in Korean Changguek costume is more used for white robe preference thinking, but black in Kabuki costume is much more used for symbol of power in Japan. The similarity of Korean and Japanese cultural color is to use much Obangsaek, less Ogansaek by the theory of exponents of the five elements doctrine, but the difference of Korean and Japanese cultural color is to use color differently according to preference thinking system.

This study aims to prepare the basic data of the teeth color by measuring analyze mode using the color of the maxillary anterior teeth (maxillary central incisor, lateral incisor, canine) of the college students in their twenties as the dental colorimeter. The maxillary anterior teeth of the subjects of study as 467 students (male 89, female 378) were measured from 14 November to 2 December, 2011, so the color of total 1,401 teeth was examined, and oral health and eating habit attributes were researched. The survey results were as follows. 1. The color of maxillary anterior teeth was changed from maxillary central incisor to maxillary canine, brightness ($L^*$) was decreased $76.79{\pm}4.86$ to $69.72{\pm}4.62$, red chroma ($a^*$) was increased $2.02{\pm}2.00$ to $4.10{\pm}2.60$, yellow chroma ($b^*$) was increased $15.51{\pm}3.42$ to $20.10{\pm}3.46$. 2. Brightness ($L^*$) was different according to sex (p< 0.001), major (p<0.001), grade (p<0.001), smoking (p<0.001), oral health education (p<0.01), daily brushing frequency (p<0.001), brushing method (p<0.05), oral hygiene devices (p<0.001), and red chroma ($a^*$) to major (p<0.001), daily brushing frequency (p<0.05), brushing time after meals (p<0.01), oral hygiene devices (p<0.01), and yellow chroma ($b^*$) to brushing time after meals (p<0.01), subjective tooth color (p<0.001). 3. Brightness ($L^*$) of eating habit attributes was different according to coke, candy ($R^2=0.053$, p<0.05). In conclusion, this study demonstrates that the color of maxillary anterior teeth has differences in brightness ($L^*$), red chroma ($a^*$), yellow chroma ($b^*$) from each tooth, also these showed various tendency according to the oral health and eating habit attributes.

Cotton and ramie fabrics were dyed with artemesia and gardenia dyeing solutions. The chroma values of the fabrics dyed with gardenia were higher than that of artemesia. The ramie fabrics dyed with gardenia showed higher chroma values than the cotton fabrics. The colors of fabrics were deeper in shade but their chroma values were improved no more by repetition of dyeing process in artemesia dyebath. The two ways of dyeing processes were carried out. In the first wan, each fabric was dyed in 5 different concentration(1∼5%) of gardenia dyebath to get the fabrics dyed in different shades. After then the gardenia dyed fabrics were dyed again in the artemesia dyebaths. In the second way, the 5 fabrics were dyed in different shades by repetition of dyeing process in artemesia dyebath. After then the artemesia dyed fabrics were dyed again with the gardenia dyebaths. When the artemesia dyeing process was added on the fabrics dyed in five shades with gardenia, the color differences between five samples were slight. But when gardenia dyeing process was added on the fabrics dyed in five shades with artemesia, the samples showed different hue of colors between yellow and green of Munsell color circle. Like almost of fabrics dyed with Plants materials, the colorfastness to light and laundering of the dyed samples were poor But the colorfastness to drycleaning was good.
