Colour properties can be classified based on hue, brightness, and saturation, and the characteristics of colour perception vary by colour property. In terms of colour perception, surrounding colours are viewed together rather than independently, and the characteristics of the original colour perception may vary depending on the colour characteristics of the surrounding. Thus far, research on colour perception and sensibility has focused on a monotonic environment, which is different from colour perception in real life. As such, a fundamental study on colour perception considering surrounding colours must be conducted. In this study, a psychophysical experiment was conducted, and the results were analysed to study the colour perception characteristics by edge brightness, Edge brightness was set as a variable based on the visual traits that are most sensitive to brightness, and the experiment was conducted using the Munsell colour system to specify the stimulus colour. Based on the analysis of the experimental outcomes, this study reveals the significance of fundamental research data on the visual and perceptual characteristics of colour perception with regard to edge brightness and provides directions for future research.

This research was carried out in order to suggest useful data for planning fabrics of summer eco-friendly fashion products. For this purpose, four cellulose fabrics were dyed with natural indigo under three different dyeing conditions, then, their colorimetric properties and color sensibilities were evaluated, and their influences on color preferences were analyzed. All cellulose fabrics naturally dyed with indigo showed the characteristics of PB color tones, middle and low value, and low chroma. Color characteristics were significantly different according to fiber type and dyeing condition. The color sensibilities of the fabrics dyed with indigo were classified into three factors: sporty, classic and natural. These sensibilities showed partially significant differences according to fiber type and dyeing condition. Also, there were partially significant relationships between color characteristics and the color sensibilities of the fabrics dyed with indigo. The color preferences of the dyed fabrics with indigo were found to be influenced by the sporty and classic of color sensibility and $L^*$ of color characteristics.

This study was carried out in order to investigate the colorimetric values, the color sensation and sensibility for naturally dyed fabrics with microbial prodiginine colorant and to find out the relationship among color sensation, color sensibility factors and colorimetric properties of them. Color sensation and sensibility of four different fabric stimuli coloring red purple by a microbial prodiginine colorant produced from Zooshikella sp. were subjectively evaluated by university students. The color sensibility for the naturally dyed fabrics was classified into four factors: 'pleasantness', 'gracefulness', 'characteristic' and 'relax'. Color sensibility factor 'pleasantness' was the dominant factor for the naturally dyed fabrics with microbial prodiginine colorant. All color sensibility factors showed a significant correlations with the color sensation and colorimetric properties of the dyed fabrics with prodiginine. There were showed significant relationships between the color sensibility factors and lightness $L^{\ast}$, color saturation $C^{\ast}$, $a^{\ast}$ and $b^{\ast}$. Also, color preference of the dyed fabrics with prodiginine was found to be influenced mainly by color sensibility factors.

In this study, the Bookstore Block of Historical and Cultural Street in Kaifeng City is taken as the object, which makes analysis on the landscape color features appearing in the elements of the bookstore block landscape. Through literature, it obtains the contrast list for the landscape composite elements of the historical and cultural street. After mastering the general characteristics of architectural colors and basic analysis methods of landscape colors in the Qing Dynasty, it conducts the site survey on the landscape composition elements and colors of the bookstore block. According to the conclusion, it is found that the landscape color of bookstore block is composed of R series, PB series, Y series and achromatic (N) series, in which the overall color shows relatively high integrity. However, it exists some deficiencies in the use of colors in signs, facilities and modeling objects. Therefore, it is necessity to increase the color plan of landscape elements such as signs, modeling objects and facilities, enhance the recognition possibilities of visual information.

This study was carried out in order to investigate color sensation and sensibility for yellowish natural dye fabrics and reddish ones and to establish prediction models for color sensibility factors of them by color sensation and the related physical measurements focusing on 40s middle-aged people. Eight fabric stimuli which were dyed with a variety of yellowish or reddish natural dyes was subjectively evaluated in terms of color sensation and sensibility by 40s aged participants. As results, three color sensibility factors including 'Active', 'Characteristic', and 'Relax' were extracted and they were examined in respect of their relationships with color sensation and physical color properties. Color sensibility factor 'Active', the dominant factor for the naturally dyed fabrics was explained by $L^*$ and sensation 'Deep' in its predictive model and a yellowish fabric dyed with 300% solution of armur cork unmordanted was perceived the strongest in the factor. Factor 'Characteristic' was predicted by both $a^*$ and sensation 'Light' and reddish natural dye fabrics tended to be felt more strongly for it. Color sensation 'Strong' was the only predictor for factor 'Relax' in that naturally dyed fabrics with lower values for the sensation seemed to show higher 'Relax' factor and a reddish fabric dyed with safflower 125% was the highest for the color sensibility factor. These results could be utilized to design color-sensible natural dye fabrics for middle-aged people.

Based on Goethe's color theory, this study presented concepts and classification methods through the following research methods for the purpose of defining sensory, emotional, and experiential colors as spatial colors in digital space. First, the concept of spatial color is defined through theoretical consideration and three (3) types of spatial color are classified as the surface, outline, and physical colors. Secondly, the study includes the characteristics of digital space and color sensory type. Third, based on the identified color sensory type through the previous theoretical consideration, the four (4) categorized digital spatial color were derived and presented as techno Chromatic, S.E.N.S.E, pixel, and blur colors were determined and proposed. Based on such research contents, this study is meaningful in that it systematized the meaning of Goethe's color theory in the present age through digital spatial color.

This study was performed in order to suggest useful data for color planning of eco-friendly and sensible fashion products. Silk fabrics were dyed in combination with natural indigo and Japanese pagoda tree and were treated with four kinds of mordants after combination dyeing. Then, their colorimetric properties were evaluated. From these composite-dyed silk fabrics, color sensibilities and color preferences of green yellow (GY) color were evaluated among the female university students, and thus, the influences of colorimetric properties and color sensibilities on color preferences were analyzed. When the silk fabrics were dyed in the combination of natural indigo and Japanese pagoda tree and were treated without mordants, they turned green color when indigo 10 g/L was used, and blue-green when indigo 20 g/L was added. And when they were dyed in combination of natural indigo and Japanese pagoda tree and were treated with four kind of mordants after combination dyeing, they turned GY color in almost all cases. The color sensibilities of the GY silk fabrics with the combination dyeing of indigo and Japanese pagoda tree, were classified into three factors: pleasantness, gracefulness, and comfort. Color sensibility factors showed significant differences according to the concentration of indigo and the kinds of mordants. There were almost significant relationships between colorimetric properties and color sensibilities factors of compositely dyed GY silk fabrics. The color preferences of the GY fabrics, which were dyed in the combination of using natural indigo and Japanese pagoda tree and four kinds of mordants, were found to be predicted by the color sensibility in a regression model.
