The purpose of this study is to confirm the international unique color sensibility according to the ethnic color preferences. The existing studies about color sensibility were investigated to analyze the international color sensibility. The countries were chosen according to its, strong regional and racial color. Also, the documents and websites about environment color such as structure color, natural feature color, traditional folk costume color and customary color names were investigated, and then, the international color sensibility was analyzed by using the color image scale. As a result of the analysis about the differences of color sensibility, internationally distinguished color sensibility was discovered. There were differences not only for the preference trend of hue but also for the tone or contrast of color among the selected countries. Especially, Great Britain had a strong preference for G categories that they preferred the warm-grayish color image. Russia has a preference for R, G, and B categories with the preference for the warm-clear image. Netherlands had a preference for R, Y, and PB categories and it preferred the cool-hard-grayish, warm-soft-clear image. Italy had a preference for R and Y categories and it preferred the warm-clear image. Morocco had a preference for R and B categories and it preferred the warm and cool, clear image. Japan had a preference for R, G categories and it preferred the warm-grayish image. Korea had a preference for R and B categories and it preferred the warm-soft-clear, and cool-clear image. With these results, the researcher concludes that the integrated analysis of the environment color and the traditional racial color factors are very persuasive methods to comprehend the international color sensibility.

In contemporary times, there is an increasing demand for a dedicated healthcare environment, all over the world. The main motivation for this demand is the level of awareness manifested by the users and reflected on their expectations. Therefore new research strategies and design actions are investigated in order to answer to the users' needs and to provide objective design tools for the specialist. This study continues a series of previous developments of the Healthcare Environment Color Index that should be used for public facilities in Korea and abroad. The cross-cultural approach is a new opportunity for exchanging know-how and for testing and calibrating the perception of the users on the color index. The gathering of results was made based on the online survey provided in this phase in English version for the Romanian users. The survey was intended as an objective mean of research and an efficient way of disseminating information on the subject thus contributing to increasing the level of awareness of the users. A total of 86 Romanian and 89 Koreans with valid answers took part in the survey. Comparative visualizations of the results showed significant similarities concerning the patterns of color preferences but also cultural and emotional differences. As a result both categories of users proved to be aware of the relation between healthcare environment color and its effects on health. They also showed a common understanding on the potential of the color index. As a result the most appealing colors to be applied to the healthcare environment were the series G and B, and the most effective ones were proved to be the ranges of high lightness and low saturation but also the medium high lightness and medium saturation. Both the similarities and the differences of choice between Romanians and Koreans show that cultural and emotional differences of color recognition are important and that should be taken into consideration in design, in order to generate an inclusive and efficient healthcare environment.

Color is a significant factor for evoking human emotion. Therefore, the effects of color have been analyzed to predict and evaluate human emotion. The purpose of this study was to measure the cardiovascular responses depending on color stimuli in order to observe differences in color-emotions. Images consisting of six colors (red, green, blue, cyan, magenta, yellow) were used as visual stimuli. 26 college or graduate students (13 males) watched the color stimuli on the monitor and scored their subjective emotion while electrocardiogram (ECG) was meausred. The effects of the color on emotion were tested using Kruskal-Wallis test and Mann-Whitney U test. The coherence ratio showed significant differences between green and magenta (p = .004), green and red (p = .006), and green and yellow (p = .004). The significant differences of cardiovascular and emotions were relevant to emotional valence. This study shows significance as an empirical study by indicating that green induces pleasant and red induces unpleasant.

The study is about how the difference in education levels can affect the subjects' use of color and find out the features of the effect. This experimental study focused on the differences in color expression using the outline picture of a painting before and after being exposed to a full-color picture of the original painting. Differences between two conditions with two different stimuli were observed and the cause of the differences was analyzed based on the number of colors and the quantity of colors and composition of the colors used by the subjects. The study precedes an experiment based on how the level of education though experience can affect the use of colors. This study is focused on the various effects of color usage by children and adults who have various degrees of visual experience. In addition, the study analyzes how design majored subject differed in the use of color from non-design majored subject and compares the use of colors by the two groups. The results showed that design majored subject tended to use less coloring patterns after seeing the stimulus of the Monet picture with more colors, and included the colors from the stimuli they were exposed to. The non-design majored subject who viewed the Mondrian painting demonstrated opposite results by using less number of colors than before seeing the stimuli. In comparison to design majored subject, the variations in selected colors and the quantity of color by non-design majored subject were not consistent.

Recent color plans in school buildings are made by experts through public offerings for prizes for designs etc in relatively many cases. But it is necessary to review if such color plans are actually well conform to students' emotions and what trend the color plans made as such have. Therefore, this study examined and analyzed the exterior colors of the school buildings planned by public offerings for prizes for designs and reviewed the result comparing to the color preferences of students that had already been studied to figure out the differences between existing theories and the realities. And it was examined what differences were existing in the trends of color plans and color images examined between each of school levels. The result of the study compared to theories is as follows. First, when the color distributions were reviewed for each school level, it could be confirmed that the overall distributions moved from Y category to B category and whereas warm colors were more widely distributed and the number of colors were greater compared to cold colors in case of elementary schools, the distributions of warm colors gradually decreased as school level moves to high schools. Second, the color use distributions of elementary school students were revealed to be more diversified than middle and high school students and also the number of colors used was 9.5 in average in elementary school and middle schools and high schools were similar to each other with average 5.86 colors in middle schools and 6.33 colors in high schools showing a little differences in color use distributions among school levels of elementary schools, middle schools and high schools. Third, in case of elementary schools, except main colors, both of subsidiary colors and emphasizing colors had the distributions of warm colors of R, YR, Y categories and cold colors of B, PB categories and this is also consistent with the results of existing research results indicating that low grade students prefor for warm colors and high grade students prefer for cold colors. Fourth, in case of middle schools and high schools, although the distributions of warm colors decreased, the distributions of warm colors and cold colors were revealed to be similar. This is considered to be consistent with the existing research results indicating that girl students prefer for warm colors even if their ages go up. Fifth, as for the images of main colors, subsidiary colors and emphasizing colors resulted from the comparisons by solid color Image Scales and adjective Image Scales, first, in case of main colors, natural images or clear images appeared the most in all of elementary schools, middle schools and high schools indicating that basically calmness is emphasized with soft images rather than hard images and static images rather than dynamic images. Also, in case of subsidiary colors or emphasizing colors, cheerful images or splendid images are also seen to decrease as school level goes from elementary schools to high schools in adjective Image Scales and this is considered to reflect the color sentiment differences between children and juveniles based on ages.

PURPOSE. The aim of this study is to evaluate the effect of resin cement color, cement thickness, and thermocycling on the final color of monolithic lithium disilicate crowns. MATERIALS AND METHODS. A total of ninety prepared central incisors of typodont teeth were restored with lithium disilicate crowns which have different cement thicknesses (40 ㎛, 80 ㎛, and 120 ㎛) and cement shades (clear, yellow, and white). Color parameters of restorations were measured with a spectrophotometer in three different steps 1) before cementing 2) after cementing and 3) after thermocycling with 10000 cycles. Color differences (ΔE₀₀) were calculated with the CIEDE2000 formula and evaluated according to perceptibility (0.8) and acceptability (1.8) thresholds. The ΔE₀₀ data were analyzed by using two-way ANOVA before and after thermocycling (α = .05). RESULTS. There was no interaction between the cement shade and the cement thickness factors. After cementation, the mean ΔE₀₀ was under the perceptibility threshold in the group of 40 ㎛ cement thickness and clear cement while it was between the perceptibility and acceptability thresholds (0.8 < ΔE₀₀ < 1.8) for all other groups. After thermocycling, the ΔE₀₀ values were between the perceptibility and acceptability thresholds for all experimental groups. Although there were no significant differences among the groups, thermocycling increased the color difference values. CONCLUSION. The cementation of restorations with clear, yellow, and white resin cements resulted in color differences with uncemented restorations except for the group cemented with clear cement in 40 ㎛ cement thickness. All study groups revealed perceptible color change after thermocycling.

The composite resin, due to its esthetic quality, is considered the material of choice for restoration of anterior teeth. To get a satisfactory result in the composite resin restorations, it is necessary to choose right shade. At present, most of the commercial composite resins are based on the Vita Lumin shade guides or shade guides that are provided by their company, but color differences among them might be expected even using the same shade in various materials. This study is to measure color differences between various light-cured composite resins and shade guides and to provide the clinicians with information which may aid in improved color match of esthetic restoration. Four kinds of light-cured composite resins (Gradia Direct (GD), Z250 (Z250), Clearfil AP-X (AP-X), Esthet X (E X)) and shade guides with A2 and A3 shade were used. Three specimens of each material and one specimen of each shade guide were made. Each composite resin was filled into the Teflon mold (1.35 mm depth, 8 mm diameter), followed by compression, polymerization and polishing with wet sandpaper. Shade guides were grinded with polishing stones and rubber points to a thickness of approximately 1.35 mm. Color characteristics were performed with a spectrophotometer(color i5, GretagMacbeth, USA). A computer-controlled spectrophotometer was used to determine CIELAB coordinates ($L^*$, $a^*$, $b^*$) of each specimen and shade guide. The CIELAB measurements made it possible to evaluate the amount of the color difference values (${\Delta}E^*ab$) between composite resins and shade guides. CIE standard D65 was used as the light source. The results were as follows : 1. Among the $L^*$, $a^*$, $b^*$ values of most of 4 kinds of composite resin specimens which are produced by same shade, there were significant differences(p<0.05). 2. Among all 4 kinds of composite resin specimens which are produced by same shade, there were color differences that is perceptible to human eye(${\Delta}E^*>3.3$). 3. Between most of composite resin specimens investigated and their corresponding shade guides, there were color differences that is perceptible to human eye(${\Delta}E^*>3.3$). 4. In the clinical environment, it is recommended that custom shade guides be made from resin material itself for better color matching. Shade guides supplied by manufacturers or Vita Lumin shade guide may not provide clinicians a accurate standard in matching color of composite resins, and there are perceptible color differences in most of products. Therefore, it is recommended that custom shade guides be made from resin material itself and used for better color matching.
