  • This Paper is intended to analyze color preferences for apparel, and color preferences according to personality types. The subjects are one hundred twenty five female university students majoring in clothing, textile & design. Color stimulus are divided according to season, value and chroma, and personality types are classified into four : introverted, achieving, age-gressive and conservative. Duncan test, factor analysis and descriptive statistics have been applied to data processing. The findings are as follows. In terms of hue preferences, winter colors are most preferred and autumn colors follow. In re-gard to value preferences, low value colors have been found to be preferred and in respect to chroma preferences, low chroma colors have been found to be preferred. Seasonal colors, value and chroma show significant differences at the level of P<.001. In terms of color preferences for apparel fabrics according to personality types, winter colors are most preferred regardless of person-ality types, and autum colors follow. The introverted and the conservative dislike summer colors least and the achieving and the aggress-ive, spring colors. In respect to value preferences, low value colors are preferred irrespective of personality types. The introverted and the achieving dislike high value colors least and the aggressive and the conservative, mid value colors. With regard to chroma preferences, all person-ality types have been found to prefer low chroma colors. They dislike mid chroma color, and high chroma colors are least preferred.

  • This study intended to propose a guideline designed to secure safety by developing a functional color design for the color of the ordinary working clothes worn in the actual industrial settings of the machine industry in national industrial complexes in Korea. For this, a total of 6 sets of actual working clothes were produced for test, using 2-color arrangements with blue, of varying brightness and chroma for top and bottom, in relation to the visibility proven in preceding studies and evaluated in the machine industry. Blue was suggested the best proper color for machine industry by previous studies. For the material of working clothes, a total of 111 swatches were collected from the Dongdaemoon Fabric Market, and they were analyzed for color values. A total of 6 materials were used to produce working clothes for testing, which represented high brightness, medium brightness, low brightness, high chroma, medium chroma, and low chroma. Clothes were tried at the industrial settings for machine industry in a national industrial complex located in Gyeongsangnam-do and the expert satisfaction evaluation was performed based on items related with safety. As a result, higher satisfaction was shown when the brightness difference of top and bottom clothes was greater, and for chroma, relatively higher satisfaction appeared when the chroma of both top and bottom clothes was high. To secure satisfaction for both brightness and chroma, it is possible to deduce that the 2-color arrangement using the strong tone with high brightness and high chroma and the dark tone with somewhat low brightness and high chroma would be effective. Top and bottom clothes in the same color with high chroma had high visibility but had somewhat low evaluation for harmonious arrangements. This indicated that the arrangement of vivid colors for top-bottom clothes is inappropriate.

  • 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.

  • This research is to study the functional color arrangement of work clothes based on the color chroma value arrangement, which could affect the safety of workers at the site of the mechanical industry. For the study, 5PB hue, indicating a high satisfaction level with proper colors at the site of the mechanical industry, were selected from previous research for 6 types of CAD simulation on a 2-color chroma value arrangement. To analyze the color data of each color arrangement after applying the color chroma value arrangement as well as to figure out the level of recognition on the color arrangement, an analytical result, which was based on the NCS color system, was evaluated. Furthermore, the survey study on items regarding the safety of the relevant work site for the simulated result was executed. As a result of the evaluation, the color arrangements which include high color chroma value indicated a high satisfactory level in all items under the visibility criteria for the safety of workers, propriety as a color arrangement of work clothes, and safety from the perspective of work site management. In particular, the color arrangement mixture between high color chroma obtained the highest satisfactory evaluation, indicating that the color arrangement of high color chroma is essential in the color arrangement of work clothes for the establishment of safety by adjusting the color chroma value. Yet, in order to figure out the independent function of the color chroma value, other factors are restricted in this study. Thus, it is not proper to apply the result of this study only at the actual work site. Therefore, a follow-up research centered on the tones of all three types is proposed, from which we can expect, a suggestion of the applicable color guideline for the industrial site.

  • The purpose of this research was to investigate the effects of clothing style and color of male casual wear on image perceptions and age evaluations. $4{\times}2$ (top color${\times}$trouser color) and $2{\times}3{\times}2$ (clothing style${\times}$clothing hue${\times}$clothing chroma) factorial designs were used as the experiment designs. Photoshop program was used to manipulate the clothing colors after creating photos of models wearing experiment clothing for stimulus. Subjects were 280 female college students from Seoul region and each subject responded to two stimuli. Factor analysis showed four factors of images of male casual wear; sociability, conspicuousness, softness and masculinity. Polo shirts were evaluated higher in sociability and softness than jumpers and nary blue trousers were evaluated higher in masculinity than beige trousers. High chroma clothing was assessed higher in sociability and conspicuousness than low chroma clothing. High chroma red jumpers displayed very sociable feel and low chroma blue jumpers displayed the lowest sociability. High chroma male clothing resulted in younger age perception but age was evaluated young when a black shirt was worn under the jacket when wearing a low chroma jacket.

  • This study tried to search the defferences between color designer's intentions of the exterior color design in elementary school design and the students' recognitions. I made a questionare for the elementary school students who are in the 3 schools which are located in the north Kyung-Gi Do. I got the some conclusions as follows. First, the elementary students have different recognitions of the exterior color of the school from coloer designers' intentions. Second, with fixing the Hue, changing the Value and Chroma, the students have more preferances than before. And they have more preferances in high value higher than N8, and they have more preferance lower than 4 in chroma. But in chroma, they have highest preferance in existing status which are low chromas. Therefore, when exterior color designing in elrmentary school design, designer must consider high value higher than N8, and low chroma lower than 4.

  • In this study, the colors and characteristics of Gwangbok-ro of Busan were analyzed in the standpoint of local images based on the examination of the facade designs of stores along the road of Gwangbok-ro, Busan a main street with massive population flow. To that end, the facades of stores, correlation with the city, color and locality were examined, and after the status of facade designs in Gwangbok-ro were identified through case survey by it, color images were analyzed. For color analysis, Munsell color system was used as basic tool. As a result of examining the colors in Gwangbok-ro area, the following status could be analyzed on 3 attributes of hue, brightness and chroma: First, analysis results of hue indicated that dominant color that covers 70% or more of the area represented mid brightness and low chroma in GY(36.1%) series, subsidiary color which covers 25% or more of the area mid brightness and low chroma in YR(26.5%) series, and accent color that covers less than 5% of the area high brightness and low chroma of GY(40%) series. Second, in brightness analysis, dominant color mostly represented mid brightness, subsidiary color mid brightness and accent color high brightness respectively. In particular accent color showed more intensive crowding phenomenon in high brightness. Third, as for chroma, dominant color, subsidiary color and accent color all are gathered in low chroma, however in small number of accent colors, peculiar high chroma appeared notable. In conclusion, the colors of Gwangbok-ro area analyzed based on the facade design of the stores along the road in this study were superficial colors that reflect the life of people in the area, artificial colors by improvement of the local environment. This study is meaningful in that the image of Gwangbok-ro was found through building colors in one part of the city Busan. It is judged that the study results would become useful as reference document in planning out environment colors later on.

  • Japan has several unique traditional colors. The traditional colors of Japan include a collection of colors used in traditional Japanese literature, textiles such as the kimono, and other Japanese arts. Japanese color system has a long history, leading to some consistencies in color and naming. During the Edo period(1603~1867), the unique color sense of 'iki' produced many color names that are often related to mouse(nezumi) and tea(cha), and fashion color originated as kabuki actors. As for colors named after animals, the most popular appears to be the mouse, which is used to express grey tones. Recently, many fashion companies in Japan have been working on reviving an interest in traditional Japanese colors. Ordinary people of Edo named even slightly different color tones, each with individual exquisite and mind valuing 'iki' senses. They translated these into their livelihood and culture. The colorimetry result of 49 restored dyed fabrics were as follows; Hue difference was 7.8, value difference was 2.9, chroma difference was 1.8 of prefix siro. Hue difference was 3.8, value difference was 1.6, chroma difference was 1.7 of prefix usu. Hue difference was 3.5, value difference was 1.5, chroma difference was 1.4 of prefix cha. Hue difference was 6.4, value difference was 1.1, chroma difference was 1.6 of prefix koi. Hue difference was 7.5, value difference was 0.8, chroma difference was 3.3 of prefix nezumi.
