  • We compared the electroencephalogram, blood pressure, and sensory evaluation inspectioni several color of Petunia hybrida to analyze the physiopsychological effects of a plant. Considering occipital is related to visuosensory field, green color is thought as mild visual stimulator unlike to pink color. The results are coincident with the well-known facts that green color is less stimulating color. It is also accorded with the sensory evaluation results that green color showed te feeling of blue and stable. In case of green color is showed the feeling of blue and stable. In case of green color the generatioin of alpha waves increased according to the increase color area. Therefore it is thought that green color helps decrease of visual stimulation and increase in visual stability. However it is thought that pink has less physiopsychological effects on human beings depending on area sizes than green has.

  • Color is an important subject of interest for cognitive developmental stages of children and it also correlate to emotional and physical development. Children can acquire concept of color by 'play'. Color play can be experienced to children through diversity activity and theses activities contain creative craft art activity. The color-paly with art activity for kids can be called 'kids color-design play'. Recently, indoor playgrounds are rapidly grow-up because parent's concern degree that about play activity get higher. The indoor playground being enlargement and it contains various paly contents. Color-design play is also enacted animatedly in kids indoor playground. The great part of color-design plays are enacted through program that needs teaching. On the other hand, color-design play facility that children can play spontaneously is not composed sufficiently. Therefore this study aim at design proposal of 'Kids color-design playground apparatus' in indoor playground.

  • This research was performed to investigate the physical properties and color appearance of Hanji manufactured using bast fibers dyed separately by two reactive dyes with different colors. The breaking length of color Ha was above 7 km. The fastness was five grade; the use of reactive dyes made the color of the Hanji not to be faded away. The Hanji manufactured by mixing uniformly two types of bast fibers separately dyed showed the mixed color of two different colors. However, the shives showed their original colors, resulted in irregular color patterns all over the sheets. The color of color Hanji with different colors in the front and back side of sheets showed color difference between front and back side of the sheets. Accordingly, the color of the sheet has a reflection from the backside, resulted in Pink. The colors of the Hanji appeared in this study could not be found from the Hanji manufactured by traditional methods.

  • In order make natural food color from gardenia(Gardenia jasminoides), we investigated optimal conditions of color extraction, in case of water extraction, optimal conditions for color extraction were 7$0^{\circ}C$, 48hrs, pH 7.0 and substrate 10%, respectively. And extracted crude color was purified by activated white clay, were isolated glycoside peak (238nm) and yellow color peak(40nm) from extracted crude color. The pruified color was increased by 27-fold and the yield was 96%.

  • Contemporary architecture pursues new method of Interpretation of Non-linear space as digital media appears. As various materials and new methods can be used due to developments in science and expansion of thinking, contemporary architectural color developed extensive possibilities. It means not only the change of drawings, method of architectural product and materials but also the change of value system for architectural space. Thus the purpose of this paper is to suggest interpretation of space applied by color structure, and this point of view was based on the three elements of color perception which are light source, reflector, and observer. According to this categorization, architectural color of exterior color, layer color and interaction color are explained via examples of colors recently used on the contemporary architectures. In summary, contemporary architecture can be explained by Non-construction space interpretation for intrinsic complex meanings. Therefore, it can be explained as moving space, collage, by picturesque space, moving blur color and emptiness of color. This pursues various point of views for space interpretation, therefore it can be developed to the identity of strengthening architectures' design concept.

  • The purpose of this study is to identify the color combination characteristic and to find out the characteristics of color tones in interior environments of Korean traditional houses. The results of the interior color combination analysis, it was revealed that contrast was the most dominant in architectural elements color. In the furniture, graduation, contrast and analogous harmony were mainly used. Single color harmony, analogous harmony, complementary harmony were the dominant color combination characteristics in interior accesories. Color tones of architectural elements were dull and light(pale, light grayish, light grayish) and color tones of furniture were dark and dull(dull, dark, dark grayish). However, interior accessories of an-bang show wide range of color tones raging vivid to dark tone, while sarang-bang accessories have tendency to soft, gray and dull tones. Therefore, the color tones of an-bang and sarang-bang elements show clear differences.

  • Recently, as the prepress mainstream is changed to the digital workflow, various digital proofing systems such as high price dye sublimation printers and low price ink jet printers are widely used in printing industry. However, most of the digital proofing devices have lower resolutions than analog proofing systems and differ with actual color presses in the color gamuts. Therefore, proper color compensations are needed for digital color proofing in order to match color between the proofs and the press sheets. In this paper, we used 3-dimensional look-up table(LUT) and tetrahedral interpolation method for the color space conversion between the device independent color space(CIEXYZ or Lab) and the device dependent color space(CMY) to reduce the color differences between the original copy and digital color proofs and the press sheets.

  • The general commercial printing meets the customer's diverse demand by using spot color besides process four color. Especially, by using spot color for printing the enterprise's logo or specific color, we can see the effect of printing is getting better. The objective of this study was to examine the quality of spot color reproduction with Inkjet for 2 types of paper and Dye sublimation in ICC-based color management system. ICC profiles were generated for each device using ECI 2002 visual target and evaluated for the accuracy of each printer's color profile. The test chart consisting of Pantone color 1140 was selected to test the quality of spot color reproduction.

  • The propose of this study investigated the reproduction of color image on a CRT monitor, for a range of different values of monitor gamma. We have used the GOG(gain-offset-gamma) model of the behavior of CRT. Color difference have been computed in a color space, based on the CIELAB color appearance model. The 133 patch defined linearly color sample and 24 patch defined printing color target were used, and were subjected to the influence of nine different gamma value. The result shows that netural color is increasing the decrease range of luminance black color than white color. These results concern correct in the context display of color reproduction.

  • There has been an enormous emergence of imaging systems dedicated to hardcopy and softcopy color-appearance comparisons. Pre-press industry use the CRT as a soft proofing device to preview and aid with color corrections and changes before producing the final printed image. Color DTP system is required an accurate image-matching between CRT-image and printed image. In other to develop the color DTP,CRT calibration and CRT color transform to CIE color system are necessary. In this paper, we described a method CRT color transform to CIELab color system using RGB image raw data. Experimental results show that described method is useful valid of color image matching.
