Black-dyed PET fabrics were sputtered with stainless steel through DC-magnetron type device to investigate the possibility of coloration effect, and then considered the morphological structure and physical characteristics such as water permeation ability and washing fastness. Change in color was estimated on the basis of CIELAB color system. The color coordination of metal plated PET was shifted to yellow-red from red-blue. Colour difference$({\Delta}E^*)$ was increased by sputtering conditions with increasing ion current and treatment time. Especially, $Lightness(L^*)$ value of PET was remarkably increased by sputtering, whereas $Chroma(C^*)$ increased gradually. From SEM analysis, rough and uneven craters were found and thickened on the fiber surfaces with longer sputtering time. And washing fastness was a little poor and absorption ability slightly decreased. There were little changes of breaking load and breaking extension. It was evident that observed uneven craters in the plated thin layer resulted in the colour change of PET fabrics by sputtering treatments.

The five new red disperse dyes for unmodified pure polypropylene fibers were synthesized. As a coupling component, a di-n-hexyl substituent was used in common, while various substituents were used for the diazo component. The dye having electron donating group at diazo component showed hypsochromic shift compared to the unsubstituted dye, while the dyes having electron withdrawing groups showed bathochromic shift. Owing to their extreme hydrophobicity caused by the di-n-hexyl substituent, all dyes exhibited very high affinity toward pure polypropylene fibers. Fastness to washing was very good for all dyes and fastness to light was good except two purplish red dyes.

Kiwifruits introduced to Korea typically have green fruit flesh, yellow flesh, or yellow flesh with red coloration around the core. Here, we describe a new cultivar called 'Redvita', the first kiwifruit cultivar of Korea with yellow flesh and red coloration around the core. A conventional field cross was conducted in 2003, and permission for the final release of 'Redvita' was obtained in 2012. 'Redvita' originates from 'Red Princess', a maternal vine known for the red coloration in its flesh. The pollinizer is 'NHK0013' (IT233175), which blooms in early May. A principal feature of 'Redvita' is its high vitamin C content, which at an average of 140 mg per 100 g of fresh weight is 2 - 4 times higher than other commercial cultivars. The average fruit weight is 97 g; bigger than that of the control cultivar 'Hongyang'. 'Redvita' blooms in mid-May and is usually harvested in early to mid-October, approximately 150 - 160 days after anthesis. 'Redvita' produces 3 or 4 flowers per fruiting shoot, with no small lateral flowers, therefore does not need to be thinned before blooming for commercial production. The cultivar is acidulous because of a high titratable acidity content (about 1.5%), which is higher than other cultivars (less than 1.0%). 'Redvita' was registered with the Korean Seed and Variety Service in 2015 for plant variety protection rights (no. 5604).

This study investigated the effect of a pigment (C. I. Pigment Red 122) addition on mechanical properties of the epoxy resin, diglycidyl ether of bisphenol F (DGEBF) and G640 curing agent. The K/S value, thermal properties, tensile properties, and fracture toughness of the prepared epoxy samples were evaluated. When the pigment was added to the DGEBF/G640 epoxy system, the color of the epoxy resin changed to red from transparent and yellowish color, and the K/S value in the red region increased as the pigment content increased. When the pigment content was increased up to 0.1 phr, the tensile strength was improved up to 21.8 %, whereas the pigment content was over 0.1 phr, the tensile strength decreased. The fracture toughness was improves up to 23.1 % until the amount of pigment added was up to 0.2 phr, and then decreased when the amount of the pigment added was more than 0.2 phr. This attributed to the aggregation of the pigments in the epoxy resin when the amount of the pigment added was more than 0.2 phr. Therefore, the coloration of the epoxy resin with an organic pigment must be carried out very carefully because the coloration of epoxy resin affects its mechanical properties.

This study was conducted to compare the effect of various LED and UVa light to enhanced coloration of paprika fruits cultivars; 'Special', 'Helsinki'. Immatured paprika fruits were irradiated with red LED, blue LED and UVa lights which were high intensity (red: $50{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, blue: $70{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, UVa: $3{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$) and low intensity (red: $20{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, blue: $40{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, UVa: $0.25{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$). The coloration of 'Special' cultivar was increased the fastest in high intensity UVa light for 2 days after treatment. There were no significantly difference among treatments except the low intensity UVa light. The coloration of 'Helsinki' was increased the fastest in blue LED light, and followed by red LED light and UVa light for 2 days after treatment. The $a^*/b^*$ value of 'Special' and $b^*$ value of 'Helsinki' that indicated the paprika fruit coloration were generally higher high intensity LED and UVa lights than low intensity LED and UVa lights. We couldn't find out any significantly different coloration effect among all treatments in final days of coloration. and rather than UVa treatment fruit shrunk the surface of paprika fruits.

The purpose of this research is to understand the harmony of chromatic and achromatic colors of the traditional Korean dress. The subjects were women＇s college students in Korea and America. Chromatic colon, red, yellow, and green color, were chosen for the color of the Korean jacket, and achromatic colors were chosen for the color of the skirt, and then the colors＇ chroma were controlled and value of color was changed. In addition, the three colors of the jacket were combined with four kinds of the colors＇ tone. Then, the students of both countries assessed about the harmony for 48 colorations which were variously incorporated with the tones of skirt and jacket. The results of research can be summarized as follows. When red jackets were combined with skirts of achromatic colors, students of both counties showed the different views in the range of harmony and disharmony for colorations of white(N9) skin and vivid jacket, and white(N9) skirt and dark jacket, and black(N2) skirt and light jacket, and black(N2) skirt and dull jacket. In the tone of yellow jackets and achromatic skirts, students of both counties showed similar responses in that a light yellow jacket was well matched with dark grey(N4) and black(N2) skirt. While Korean students generally evaluated that coloration was well harmonized when low value color was arranged below, American students thought, that the tones of a harmonized skirt were different, according to the jacket＇s tones. When green jackets were combined with stills of achromatic colors, colorations that showed their different views of both countries were a white(N9) skirt combined with vivid, light, dull jackets, and a light grey(N7) skirt and dull jacket, and a dark grey(N4) skirt and dark jacket. Among 48 stimuli of coloration on the chromatic and achromatic colors, Korean students evaluated 16sets and American students judged 28 sets as harmonized colors. Therefore, it came to the conclusion that Korean students had the sense of harmonious coloration of more narrow range than American students.
