Under the influence of Western culture, the style and pattern of cheongsams were significantly transformed during the Republic of China period. Color is sometimes considered as one of the symbols that can represent people’s social background and emotional preferences. The analysis in this paper was based on 414 images of cheongsam patterns from the Republic of China. To begin with, the colors were digitally extracted, and then a rule-based analysis of color style was performed. Finally, the traditional color scheme was re-applied to the new design using the user-friendly 3D virtual design software. For color extraction, the main colors of a single pattern were used as a sample, and then they were combined to provide the overall representative colors. Superpixel-based Fast Fuzzy C-means Clustering (SFFCM) and K-means split-channel clustering algorithms were employed to extract single and multiple pattern colors. In the processing of color images, the original color pixels are simplified efficiently by superpixel segmentation, so the SFFCM provides better segmentation results and takes less time than fuzzy C-mean clustering. The color distribution and silhouette coefficient were used to determine the optimal clustering number. Then the 414 images were clustered separately to extract the corresponding main colors, and a total of 1,725 color values were obtained. It can visually display the color and the proportion of the images by reducing a complicated image to basic numbers, which makes the subsequent analysis and data processing easier. After that, the number of colors was further decreased using K-means clustering to get the most representative color. Based on the HSV non-uniform quantization model, the hue values of 1,725 colors were first divided into eight categories, and then the lightness and saturation values in each category were clustered independently. Finally, they were integrated into 24 representative colors and corresponding color cards. Following the collection of data, the cheongsam patterns were analyzed in terms of both the color style and the color matching rules. The colors were primarily concentrated in yellow and red. Green, cyan, and other cool colors were used in smaller amounts. It can be seen that the costume system was changed at that time, and the use of colors was no longer frowned upon, so people had more freedom in their choices. The cheongsam pattern colors were primarily found in the low-medium saturation, medium-high lightness, and low contrast color regions, which was different from the feudal era when the clothing system mainly emphasized vivid and contrasting colors to express powerful national sentiments. The lightness and saturation of the distribution pattern caused cheongsams to be more simple and elegant in style. Meanwhile, the tonal distribution of cheongsam pattern colors was analyzed with the PCCS system. The values of the S and V channels were divided evenly, and then related to the system to ascertain the color tones and calculate their percentages. The result shows that the cheongsam pattern colors are primarily concentrated in five tones. The most prevalent is light grayish, making up 26.55 % of all colors. Grayish and soft come in second with 19.24% and 16.46%, respectively. In addition, pale and light also account for more than 8%. However, there aren’t many other colors, particularly the bright, vibrant, or others with strong color preferences, which only make up roughly 1% of the total color distribution. On the one hand, the theory of the Western color system progressively influenced people’s aesthetic tastes, and as a result, the neutral color series became the trend for garment during that time. On the other hand, the number of colors and the quality of printed fabrics were both improved concurrently with advancements in textile printing and dyeing technologies. The color matching rules are explored by the Apriori algorithm, and there are 13 two-color and five three-color matching rules discovered with low contrast between or among colors, which has some significance on the recommendation of color schemes. It can create a network of various color combinations by discovering the most representative color co-occurrences, and the method can offer more varied design possibilities based on users’ selection and confidence value. In order to test the effect of recommendations, a long cheongsam was chosen with a standing collar, one-piece sleeves, and slant opening. The style is simple and in line with the general shape of the Republic of China cheongsams, which can more naturally express the color style and design effect. The fabric pattern was incorporated into the cheongsam’s overall appearance by 3D virtual fitting software. The findings demonstrate that the color schemes and tonal collocations correspond to the traditional cheongsams with stable and elegant characteristics. Digital technology helps to analyze color schemes of cheongsam patterns in the Republic of China objectively and achieve design recommendations, which will provide a theoretical guide for re-designing cheongsam patterns.

Started from color generation theory of colored polyester, its partial and whole color generation characterization were studied. Analogized from Neugebauer formular establish in color printing, adaption of color generation for colored fibers and its color generation theory were analyzed and model was established. Color prediction accuracy verification was performed on established model by testing. Color matching theory of colored fibers and error causes were analyzed. Test results showed that blended color gamut space of ink four primary colors was larger than that of colored polyester. Found by comparing chromatic aberration of prediction color of colored fibers with practical test values, color prediction effect of Photoshop color test was better compared with that of computer color tester. Color prediction effect was affected by experimental condition, fiber blending ratio and so on. When colored polyester and white lyocell fibers were blended, chromatic aberration change trend predicted with model was basically same as chromatic aberration of polyester blending. It is considered that color prediction formular for colored fibers blending established relying on optical model and analogized Neugebauer formular is beneficial to establish color matching model for colored spun yarn accurately.

The paper sewing kits in Guizhou are a kind of daily storage item, which is mostly made of local handmade paper. The producer uses the folding method to construct a multi-layer space, and draws decorative patterns on it by hand, making the paper sewing kits both practical and artistic. In the past, paper sewing kits used to be an important tool for Miao and Dong women to engage in handicraft skills in Guizhou. In modern life, due to the lack of raw materials, long production cycle, complex production process and other factors, paper sewing kits have gradually disappeared in local people’s daily life, being replaced by some convenient machine,made products. Therefore, the research and innovative development of paper sewing kits are of urgency and important significance. This paper analyzes and studies the visual modeling of paper sewing kits using the research methods of field investigation and physical analysis in combination with the three composition principles, and sorts out the following characteristics: first and foremost, the producer draws rich and layered decorative patterns by hand on the paper sewing kits, including plant patterns, animal patterns and geometric patterns. With the help of plane composition principle, we can find that the visual patterns of paper sewing kits are organically composed of points, lines and planes of different forms organically combined on the skeleton of " Chinese characters shi (ten)" and " mi (meter)" . These patterns with the form of multiple plane composition in the plane space highlight the regular layout and rhythm of the picture. At the same time, the special material texture and original ecological preservation method strengthen the unique texture and charm of the paper sewing kits. Besides, the colors of the paper sewing kits from the external homespun packaging to the internal pattern mainly include blue, yellow, red, green and so on. It is concluded from the analysis of the color composition principle that the paper sewing kits contain the holistic harmonic color and the partial contrast color in the harmonious color relationship, and the color lightness and purity are low. These visual colors not only have decorative function but also contain cultural implications. Red and green are the two most common colors in the paper sewing kit samples seen by the authors, which is obviously related to the local color aesthetic orientation. For example, red and green are the main colors in the decorative parts of Miao women’s costumes in Xijiang. The rich colors conveying the beautiful feelings and sustenance of Guizhou minority women, are also associated with traditional folk customs and religious beliefs. Last but not least, the paper sewing kit is folded and pasted from several pieces of handmade paper, locally known as cover paper. After being unfolded successively, it contains three kinds of boxes with large, medium and small specifications. Different spaces are suitable for storing different sewing supplies. The closed paper sewing kits are as thick as a book, and it is of moderate size and easy to carry around. From the perspective of three-dimensional composition, the producers of paper sewing kits skillfully construct storage space by folding and pasting and realizing the free conversion on a plane and three,dimensional level, which fully improves the utilization rate of space. It can be seen that the paper sewing kits are a folk artwork of ethnic minorities containing the beauty of composition, and its unique visual elements provide abundant inspirations for modern design. To truly integrate this kind of traditional thing into modern life, creative integration with modern design is needed to innovate practical products that not only serve the public but also integrate culture and art. This creative mode is also an effective approach and method to activate traditional folk art in the new era. This paper interprets the decorative patterns, color collocation and structural characteristics of paper sewing kits from the perspectives of plane composition, color composition and three-dimensional composition, and excavates its deep cultural connotation. At the same time, the authors pay attention to the innovative development of paper sewing kits in modern society, hoping to promote the innovative development of traditional things by integrating the visual elements of paper sewing kits with modern design innovation, so as to better inherit national culture.

PURPOSE: To evaluate the clinical application of digital photography in special color teeth, and to explore the role and the problems s of digital photos to improve cosmetic effect. METHODS: Digital photography combined visual color- matching was applied in 50 cases with special color teeth in ceramic restorations selected randomly. Then the satisfactory degree of the patients and dentists was evaluated and the value of L*a*b* between prosthesis and its neighbors was collected by self-developed software Dental ImgShop. Chroma (Cab)and hue (hab°) were calculated according to the value of a and b. The data was analyzed with paired t test using SAS6.12 software package, so as chromatic aberration (ΔE). RESULTS: The satisfactory degree of the patients was 98%, and the satisfaction degree of the dentists was 94%. The range of L, a ,b Cab, hab ° of special color teeth was 54.50-92.29, -0.97-8.12,-0.73-20.85,0.85-21.34,29.73-89.20, respectively. There was no significant difference between the prosthesis and their neighbors statistically (P>0.05). The mean value of chromatic aberration (ΔE) was 0.948 (0.136-3.45), and only 3 cases were unacceptable (ΔE≥52). CONCLUSIONS: Digital photography could record and transmit the color information of special color teeth more exactly, and could improve the patients satisfaction and the cosmetic effect in color measuring.
