The purpose of this study is to fond out the characteristics of color perception and preferred color scheme of the aged who becomes color weak due to yellowed eye sight. For this, this study was composed of two steps. First, an experimental simulation on aged vision using Spectrophotometer(CM-2600d, Minolta) attached Y-2 filter as a quasi lenses of the aged eye. The color data of 120 color chips of the aged vision was measured and analyzed to grasp the characteristics of color perception of the age. Then, a questionnaire survey was carried out with color chips and 8 interior color schemes. They participated in a questionnaire survey of the level of identification among the color chips of 11 tones of R, G, PB, as well as a survey of the preference color schemes. The result of this study are as follow; 1) The range of color perception on hue narrowed into YR, Y, GY, G. Especially, the aged have failed perception of B${\cdot}$PB${\cdot}$P${\cdot}$RP(short wave length of light) by yellowed eye sight. 2) The level of identification among the color chips of 11 tones of R,G,PB are different by each color. But Very Pale, Pale, Strong, Vivid are fractionated similarly in almost color. 3) In the preference of interior color scheme of the aged, preference color harmony scheme Is the complementary color scheme that is easy for identification, rather than analogous color scheme. The preferred dominant color is warm color rather than cool color.

The purpose of this study is investigate the characteristics of color perception among Chinese people, and compare the characteristics among Korean, Chinese and Japanese people, using Munsell color space. The results are as follows: 1) Chinese people were more likely to tell accurately red, yellow red, yellow, purple, and an achromatic color, but did not do accurately green yellow, blue, and purple blue. In terms of a comparison of average perceived color and standard color, there were significant differences among green yellow, blue green, and blue and standard color; 2) Color perceptions of Korean, Chinese and Japanese people were broadly classified into four types. Also, of ten chromatic colors, the color perception type of only two colors, red and yellow, were is same among the groups of the three countries. However, the color perception type of yellow red, green, blue green and blue were different among them; and 3) In terms of a color perception accuracy test among the groups of the three countries, there were not significant differences between yellow and purple and standard color. However, significant differences existed between the rest of the colors and standard color.

With the progress of the aging society into the aged society, the planning of senior housing is inevitably required. Among the factors of planning, color appeals to people's vision which mostly accepts information about the environment, so age-related color vision changes should be studied. The purpose of the study is to find out characteristics of color perception focused on yellow and blue with advancing of the yellowed eye sight in the old age. The findings are as follows. (1) Regardless of gender, losses of color perception in sensitivity is occurred as aging is proceeded. But the rate of reduction is mitigated compared with the ex-research in Japan because of the promotion of physical health. (2) Human lens coloration was not common until 85 years old and the hue of yellow and red was easily perceived by the older subjects. (3) Yellow is more preferred to other colors by the elderly and accuracy of yellow-color perception is higher than that of blue-color. (4) It is especially hard for the elderly to perceive the difference between pure blue and mixture of blue-green. Therefore blue and blue-green should not be adopted simultaneously in senior housing environment. Except for the space which specially requires carefulness, various color preferred by the elderly should be applied to the senior housing environment to satisfy their psychological condition and provide the vitality of life.

This paper presents an image processing method which emphasizes a certain perception feeling on a color image. A series of fuzzy image processing schemes are proposed, which transform an color image represented in the LCH coordinate system to the image with a certain perception feeling based on the rules and fuzzy inference. To obtain the rules, results of the sensory perception tests are applied to the quantification theory. The proposed schemes can be effectively utilized in the color copy system, since printed outputs possibly look better than originals.

The purpose of this study was to investigate the scope of color perception for Japan standard color. In addition to, we compared the difference in the color perception between the Korean and the Japanese undergraduates. 140 male and 119 female Japanese undergraduates were selected as the random sample. Color perception was made with the naked eyes. Minolta Chroma Metre CR 300 was used for physical measurement of the color. The results were as follows, 1) Japanese students' perceived color perception was classified into four large groups: simple group includes Red, Yellow, Blue, White, Gray and Black, X(-axis)group includes Green, Red Purple, Y(-axis)group includes Green, complex group includes Blue Green, Purple, Purple Blue, Red Purple. 2) There is difference between Korean color perception and Japanese; for Yellow Red, Blue, Blue Green, Red Purple. 3) There is little difference between the values of standard color and mean percept color for Yellow while big difference for Blue. And as for as country was concerned, Korean is more accurate than Japanese in color perception.

The research was designed to find out the effects of design elements ; ①color, ②pattern, on image perception of clothing by using a qualitative depth interview method. The subjects were 40 women who lived in Taejon and aged 20 to 40. The interview results were both hand recorded and tape recorded for further analysis by researchers and judge groups. And the results were as follows. 1. The most preferred colors appeared to be blue and black, while stripes, checks and flowers were most favorite patterns. 2. There were individual difference in color and pattern perception, however the color image of yellow was brightness, red was dashing, green comfortable, blue cool, and black tightness. The image of geometric pattern was modesty and natural motif pattern was dynamics. 3. The tow major forces which affected the image of design elements were appeared as followed : 1) Color images affected by the image of natural objects which obtained the color. 2) Individuals past experience and emotional status also affected the personal image perception. 4. The color and pattern preference for the Koran traditional customes and Western tow piece were significantly different and this result imply cultural stereotyping on image perception of design elements. On conclusion, the results supported the research model of form perception and image evaluation.

The purpose of this study will find out the primary element of point make-up image perception, the point make-up image perception by point make-up trend and demographic variables such as sex and age. And this study will show the preferences of the point make-up. This study is based on the quasi-experimental study method with contents analysis method and experimental method. And content ana]isis is primarily based on the color trend and cosmetics colors which were suggested by a fashion magazine. Experiment was conducted by gathering opinions by poll, with the model wearing different make-ups and checking the typical reactions of people. To summarize, sex and age were found out to be influential variable to distinguish color perception abilities. This could verify that point make-up was important factor, influencing on the face image perception. also, face make-up effect could be maximized with Natural or common color groups rather than trend-oriented color group selections. And the polled preferred Natural color group with no point make-up or Classic color group to any other color group.

The purpose of this study was to investigate the scope of standard color perception for Americans and to compare the differences in color perception between Korean and American undergraduates. Sixty male and fifty-one female American undergraduates were selected as a random sample. Color perception was tested with the naked eyes. Minolta Chroma Meter CR 300 was used for physical measurement of the color. Based on the objective of this study and the data generated the following results were drawn: 1) We found no distinctive difference in color perception by different eye colors. 2) Color perception of American undergraduates is largely classified into four different groups: simple group includes Yellow, Green, Blue, White, Gray, and Black, X(-axis)group includes Yellow Red, Y(-axis)group includes Blue Green, Purple, complex group includes Yellow Red, Purple Blue. 3) The differences in color perception between the two undergraduate groups were found to be significant with four colors: Yellow Red, Green, Blue, and Purple. 4) There is a wide difference between the values of standard color and inn percept color. When undergraduates in both countries were compared, it turned out that Korean students were more accurate than Americans in color perception. 5) American students perceived Red, Yellow, and Green colors relatively correctly, but showed an extremely low degree of accuracy in Blue and Purple Blue color perception.
