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.

The purpose of this study is to provide color information in order to planning and merchandising in china fashion through the color of Beijing opera. In objective study, we collect total 302 Beijing opera images. The collecting method of source data is to extract digital color data by color picker. We transform RGB color data to H V/C, CIE L*a*b and analyze the attributes of color and tone, three-dimensional analysis. The results of this study are as follows : 1. The color distrbution of Beijing opera is R(26.9%)>YR(18.2%)>PB(11.6%)>Y(9.6%). Traditional preference color, red is most popular color as 26.7%:, the practice of vivid tone red is numerous. 2. The tone distribution of Beijing opera costume is P(16%)>It(13.9%)>d(11%)>5(9.6%)>4kg (8.2%)>b(7.1%:). The value o# Beijing opera costume distribute medium and medium-high and the chroma of those distributes low. 3. High chroma yellow is restrictive color as the symbol of emperor in china but medium-low chroma yellow is very frequently used. 4. Blue is often used in china costume. Especially in Beijing opera costume blue is symbol of bravery, dignity, cruel character 5. White in Beijing opera costume is much used for symbol of righteous loyalist. Black is less used than white in Beijing opera costume and black is authority color for symbol of the prime minister.

Retinyl Palmitate, the skin normalzer, is useful to promote greater skin elasticity, to diminish lipid peroxidation and skin roughness following UV exposure, and promote a youthfull general skin appearance. We knew that the reduction of retinyl palmitate in W/O, W/S, O/W, MLV cream was caused by variable compound factors. Among the retinoids, we chose retinyl palmitate and studied the stability behavior of retinyl palmitate is liposomed. Furthermore, HPLC, CHROMA METERS, LASER SIGHT SCATTERING SYSTEM and FREEZE FRACTURE SCANNING ELECTROM MICROSCOPY was used to analyzing the stability and efficacy of UV and heat.

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.

In this paper, lightness mapping for uniform color distribution and gamut mapping for maximum chroma reproduction are proposed. In the conventional lightness mapping, the average lightness difference between the two gamut is increased and different color changes in bright and dark regions are also increased. To solve these problems, a lightness mapping is proposed that minimizes the lightness difference of the cusps at each hue angle and produces same color changes in bright and dark regions. Also, gamut mapping that utilize variable anchor point and an anchor point are proposed for maximum chroma reproduction and uniform color change. Accordingly, the proposed algorithm can reproduce high quality images with low-cost color devices.

Using buffer solutions, consisting of pH 4, 5, 6, 7, and 8, silk fiber fabric specimens, pre-mordanted with one of the mordanting agents, Sn, Al, Cu, Cr, and Fe, were dyed using cochineal dyestuff. The color of the dyed silk fabric specimens was predominantly red(R) for the acidic range of pH 4 and 5, and predominantly purple(RP) for the neutral range of pH 6,7, with 8, with the pH boundary differentiating between the shades being between pH 5 and 6. As a general trend, the chroma value decreased as the pH changed from acid to alkali, and the highest chroma value us attained between pH 4 and 5. Regardless of the mordanting conditions, the trend was that $ {\Delta}E$ showed the highest measured value in the acidic range of pH 4 and 5, and it dropped abruptly after the pH 6.

Although design, color, and material are important elements in stage costumes, stage lightning also plays significant role in the presentation of stage costumes. Costumes color, material and perception can be significantly influenced by visual effects. Stage illumination can be arranged or managed so that colors are closely related to or enhanced or change the effects of costume colors on the runway or display at specific times. The results of this thesis are as follow; 1) Fabric tone, name, brightness, and chroma of colors were changed by the colors of stage lighting. 2) An achromatic color was changed to a chromatic color after being combined with colors of stage lighting. 3) Stage illuminations can make fabric, colors look similar to stage colors. 4) Plain satin silk fabric which reflects light shows high brightness and chroma after being influenced by stage lighting its shining effects and color changes were clear and apparent. 5) Velvet pile fabric which absorbs light shows low brightness and chroma after being influenced by stage lightning its shining effects and changes of colors were not clear and apparent. In conclusion, natural lights did not significantly influence fabric colors and perception, while artificial lights had wide range of effects on fabric colors and perception.

The tristimulus values of 180 extracted maxillary and mandibular anterior teeth were measured by colorimeter. And it were colnverted to Munsell color order system(Hue, Value, Chroma) and CIE $L^*a^*b^*$ color coordinates. The commonly used Vita, and Bioform shade guides, 2 composite resin shade guides(Prisma APH and Z-100), and a glass-ionomer shade guide(Fuji II) were compared with these teeth. At the middle facial surface, color distributions of teeth were Hue(0.56YR to 9.77Y), Value(2.46 to 7.9), and Chroma(0.14 to 2.02). And the aberaged values and standard deviations for $L^*a^*b^*$ were $63.18{\pm}10.44$, $1.11{\pm}1.66$, and $5.79{\pm}2.36$. The shade guide did not match well with the color space of the human teeth. Especially, the lacks of the Yellow-red Hues and higher values were prominent. Compare with other measurements, the Hues of the teeth measured in this study were broadly distributed(most of ranges in Y and YR were included), while the Value and chroma were shown to the lower.

This study aimed to investigate and analyze the overall color utilization characteristics as design elements of advanced men's premium outer brands. From the analysis of a total of 889 color samples, PB showed the highest distribution in color, Bk, R, and P. The use of ltg and p of high and low chroma was high, centering on dkg of low value and low chroma, and g of medium chroma. The men's premium outer brand displays a luxurious color image centered on color planning due to color contrast between dark and grayish shades. The characteristics of colors and color distribution by brand were considered. The brands that utilized the most diverse colors and shades were Herno, which pursues sportswear of the Elegance image, and Stone Island, which pursues casual images of workwear style. These results show that systematic planning using colors and shades are utilized by all premium outer brand concept. The results of this study are meaningful because they can be used as basic data for effective product planning, men's outer design development, and color planning of outer clothing brands are they represent premium outer brands for men, and identifies color characteristics as differentiated design elements.
