Exploring the potential of plant-based emulsion gels enriched with β-glucan and potato protein as egg yolk alternatives

This study investigated the microstructure, physicochemical properties, and digestibility of plant-based egg yolk (PBEY) as a potential replacement for real egg yolk (REY). The PBEY consisted of oil-in-water emulsions containing β-carotene and vitamin D in the oil phase and β-glucan and potato proteins in the aqueous phase. The potato proteins were used as natural emulsifiers and gelling agents, the β-carotene was used as a natural yellow pigment, and the β-glucan, β-carotene, and vitamin D were used to improve the nutritional profile. In aqueous solutions, β-glucan was susceptible to aggregation and precipitation. However, it remained stable in PBEY during storage, which was attributed to non-covalent interactions between the potato proteins and β-glucan. β-glucan increased the apparent shear viscosity and shear thinning behavior of the PBEY, which was attributed to its polymeric nature. The thermal gelling properties of the PBEY were also affected by β-glucan addition, with a decrease in gelation temperature and final gel strength, indicating changes in gel structure. The addition of β-glucan also increased the hardness and resilience of the egg analogs, with 2.5 wt% yielding properties like REY in terms of springiness and chewiness. The color matching theory was used to match the color of the PBEY to REY. Optimizing the concentration of β-carotene in the PBEY allowed us to successfully match the yellow color of REY. The presence of β-glucan in the PBEY increased protein hydrolysis during simulated gastric and small intestinal digestion, but it decreased lipid hydrolysis and vitamin D bioaccessibility in the small intestine. This reduced bioaccessibility was attributed to the ability of the polysaccharide to inhibit the digestion of the protein-coated oil droplets. This study provides an improved understanding of how β-glucan affects the properties of nutrient-fortified PBEY. The PBEY developed in this study may be suitable for consumers seeking healthy and sustainable plant-based alternatives to REY. However, further research is required to test the sensory properties.

Adaptive Differential Evolutionary Algorithm for Innovative Teaching and Learning in High School Project-Based Courses

Abstract In this paper, for the innovative teaching of high school project-based courses, an adaptive differential evolutionary algorithm is used as one of the tools of the project to help students solve complex problems. The traditional adaptive differential evolution algorithm has the problems of local optimum and low convergence accuracy; to overcome these limitations, this paper proposes an enhanced reverse learning adaptive differential evolution algorithm. The OL-ADE algorithm is improved by introducing the reverse learning strategy in machine learning to extract the reverse elite individual population from the original individual population and select the better-adapted individuals for mutation operation. After the project-based teaching, the students’ works have high scores in layout color matching, technical operation, organization, information awareness, and information social responsibility, and their scores are 8.6, 9.75, 9, 9.35, and 8.75, respectively. Therefore, this paper proves the Adaptive Difference Evolution algorithm’s effectiveness in innovative teaching of high school project-based courses.

Research on landscape design of Chinese museumsTaking Suzhou museum as an example

Museum design needs to consider how art and architecture can be combined to create a unique, aesthetically pleasing and attractive space. In the new Chinese pattern, a point is often used as the axis, and the elements, color matching and space proportion on both sides are symmetrical forms, showing a stable and dignified symmetry aesthetic feeling. The new Chinese style needs to be integrated into the landscape design, because the color requirements of the new Chinese style reflect Chinese characteristics. At the same time, it is combined with modern landscape materials, and the classical "national color" is perfectly integrated with modern materials. Therefore, this paper investigates the design of several museums and new Chinese style buildings, summarizes the environmental factors, functional factors, artistic factors and technical factors, and believes that environmental factors, artistic factors and technical factors are important, while functional factors are not. Finally, taking the Suzhou Museum as an example, this paper discusses the importance of several factors to provide help and reference for the subsequent museum design. The factors that should be considered in the design of the Suzhou Museum include environment, function, art and technology. The factors to be considered in the design of buildings include Functional requirements, building safety, building environment, building materials, building shapes, building costs, and building regulations.

Visual Communication Design Features Based on Traditional Animal and Plant Patterns

Abstract This paper contributes to the visual communication design of traditional animal and plant patterns by recreating the traditional pattern graphics based on the specific skeletal laws of traditional patterns. Based on the demand for vectorization of traditional animal and plant tattoos, a vectorization algorithm based on edge structure extraction is proposed to pre-process the tattoos using the gradient minimization model, and the tattoos are processed by image vectorization using the edge structure extraction algorithm of clustered segmentation and the Bézier curve fitting algorithm of the least squares method. Based on the image vectorization rendering of traditional animal and plant patterns, the visual communication design is carried out, and the color matching effect is analyzed in terms of single-factor color matching and comprehensive color matching. 10 extracted colors are analyzed in terms of the hue angle difference on the color ring, and the two comparative colors are the contrasting colors when the angle difference is 120~180°. The contrast height is highest when the difference value is 180°.

Utilizing 3D Printing Technology to Create Prosthetic Irises: Proof of Concept and Workflow.

There are currently limited treatment options for aniridia. In this context, 3D printed iris implants may provide a cost-effective, cosmetically acceptable alternative for patients with aniridia. The purpose of this study was to develop a proof-of-concept workflow for manufacturing 3D printed iris implants using a silicone ink palette that aesthetically matches iris shades, identified in slit lamp images. Slit lamp iris photos from 11 healthy volunteers (3 green; 4 blue; 4 brown) were processed using k-means binning analyses to identify two or three prominent colors each. Candidate silicone inks were created by precisely combining pigments. A crowdsourcing survey software was used to determine color matches between the silicone ink swatches and three prominent iris color swatches in 2 qualifying and 11 experimental workflows. In total, 54 candidate silicone inks (20 brown; 16 green; 18 blue) were developed and analyzed. Survey answers from 29 individuals that had passed the qualifying workflow were invited to identify "best matches" between the prominent iris colors and the silicone inks. From this color-match data, brown, blue, and green prototype artificial irises were printed with the silicone ink that aesthetically matched the three prominent colors. The iris was printed using a simplified three-layer five-branch starburst design at scale (12.8 mm base disc, with 3.5 mm pupil). This proof-of-concept workflow produced color-matched silicone prosthetic irises at scale from a panel of silicone inks using prominent iris colors extracted from slit lamp images. Future work will include printing a more intricate iris crypt design and testing for biocompatibility.

Quantifying the spatial quality of urban streets with open street view images: A case study of the main urban area of Fuzhou

With the advancement of global urbanization, urban streetscapes have become a critical part of urban public spaces. As one of the important ways to enhance the living environment, relevant government departments have accelerated the construction of urban streetscapes; however, certain issues, such as emphasis on surface and light protection, still persist. The visual effects of street landscapes hardly meet people's daily and spiritual needs. Therefore, assessing the quality of urban streetscapes has scientific and practical significance for improving urban planning and construction and creating a new intelligent and green city. In this study, the spatial distribution of vehicle interference index, spatial feasibility index, road area index, green visual index, sky visibility index, spatial enclosure index, color richness index, and visual entropy evaluation indices were drawn from the framework of combining deep learning and machine learning to quantify the spatial quality of urban streets by integrating a large number of streetscape images. The spatial quality of street landscape was evaluated according to the ELO scoring mechanism and random forest method, taking the main urban area of Fuzhou City as an example. The results showed that the overall street landscape quality of Fuzhou City was high, and the spatial distribution showed a pattern of concentrated high values in the center and dispersed high values in the periphery. Therefore, based on quantifying the spatial quality of urban streets, strategies, such as the pavement layout of pedestrian and vehicular paths, control of the continuity and permeability of visual landscape elements, and plant color matching, should be regulated. The method proposed in this study can provide novel insights for urban builders to improve the construction of cities.

Free Thoracodorsal Artery Perforator Flap for Head and Neck Reconstruction: An Indian Experience.

Background We describe our experience with use of free thoracodorsal artery perforator (TDAP) flap for head and neck (H&N) cancer reconstruction, with respect to the patient and disease profile, suitable defect characteristics, the reconstructive technique, and complications. Methods Consecutive patients ( N = 26) undergoing free TDAP flap for H&N onco-reconstruction, in a single center, were included from January 2015 to December 2018 and the data were analyzed. Results Perforator(s) were reliably predicted preoperatively, using handheld Doppler. Lateral position was comfortable for the harvest. Twenty flaps were harvested on a single perforator, more commonly musculocutaneous ( n = 16). The thoracodorsal nerve and latissimus dorsi muscle could be preserved, completely in almost all cases. The skin paddle was horizontally ( n = 5) or vertically ( n = 21) oriented, both giving a satisfactory scar. The flap was used as a single island or two islands by de-epithelializing intervening skin. Pedicle length was sufficient in all cases. Four cases were explored for suspected venous insufficiency. Two had thrombosis, of which one was salvaged, while the other necrosed. One flap had minimal partial necrosis, which was managed with secondary suturing. The 5-year follow-up showed good oral competence, mouth opening, and cosmetic satisfaction among patients. Conclusion TDAP flap provides all the advantages of a perforator-based free flap and of back as a donor site with close color match to the face, relatively hairless, and thickness in between the thigh and the forearm. It can be a useful tool to provide an ideal functional and aesthetic outcome, with a hidden donor site and minimal donor site morbidity in selected cases.

Combined application of plant extracts (tannic acid and baicalin) with acid dyes in the simultaneous dyeing and finishing of tussah silk for enhanced antioxidant, antibacterial and UV protective properties

The one-step dyeing and finishing of tussah fiber have advantages of short process, high efficiency, and energy and water saving. Additionally, to upgrade the functionalities of tussah silk fiber using natural chemicals with environmental benefits can increase its applicability. In this work, the combined application of plant extracts and acid dyes was presented for simultaneously imparting colorful shades, antioxidant activity, antibacterial activity, and UV protection capability to tussah silk. The stability of tannic acid, baicalin, and their mixtures with acid dyes was first discussed, and the colors and functionalities of dyed and finished tussah silk were evaluated. Tannic acid had less effect on the colors of dyed tussah silk. C.I. Acid Blue 113 was not stable in hot baicalin solution, and its pre-heated mixture with baicalin dyed tussah silk to dull red hue rather than blue hue. The bright blue and green colors of tussah silk were obtained by dyeing with anthraquinone and triarylmethane dyes, but their hues were affected by baicalin due to the light yellow color of baicalin and the matching of colors. Tannic acid exhibited better antibacterial property than baicalin on tussah silk, while baicalin had better antioxidant and UV protection capability than tannic acid. This work demonstrates that the one-step dyeing and finishing of tussah silk with acid dyes and plant extracts are feasible. However, special attention should be paid to the color changes of individual dyes for pale dyeing.

Evaluating Various Colors of Persistent Luminescent Powders on Rose Cut Flowers

Rose cut flowers are popular in everyday bouquets or for special occasions, and tinting of the flowers by means of color addition increases the flowers economical value and aesthetic appeal. This study evaluated red and white luminescent rose cut flowers, which was achieved by applying six persistent luminescent powders. Solutions of each color were prepared by mixing 6 g of powder and 240 ml of deionized water and sprayed four times around the flower head plus a control. Images were taken of the flowers before ultraviolet blacklight exposure and after exposure to be later analyzed with ImageJ software. Daily measurements were taken including vase weight, average floral diameter, and visual deterioration based on scale of 1 to 4. Overall measurements included mean brightness; red, green, and blue measured values; dominant wavelengths of emitted color; flower diameter change rate; relative water percent; solution uptake rate; and vase solution uptake rate. For luminescent brightness mean without ultraviolet, white rose with blue powder had the greatest value. For luminescent brightness after ultraviolet exposure, white rose with green powder had the greatest value. With ultraviolet exposure, white roses with green powder had the greatest value followed by blue, orange, and white. Red powder on white and red roses experienced little to no luminescence before or after ultraviolet exposure. Mean and mode varied in their calculated dominant wavelengths; therefore, it is recommended to use mean values because more similarities in matching of the powder color and the calculated dominant wavelength were reported. Ultimately, white roses are preferred because they seemed to have greater health and luminescence compared with red roses, and green and blue powder would be recommended for luminescent application for brightness.

Analysis of the integration path of contemporary costume culture and clothing design innovation in the context of big data

Abstract This paper uses feature fusion methods to classify the characteristics of dress culture, focusing on the application scope of pixel-level, feature-level, and decision-level. A system for recognizing dress culture classification is constructed by combining machine vision technology, and the support vector machine algorithm is used to solve the nonlinear mapping problem in two-dimensional space. The range of values of support vectors is established by using decision functions to construct a linear hyperplane. The results show that integrating the color system of costume culture and clothing design can lead to new design paths. 70% of the clothing design works have natural color matching, and 60% have color matching that can alter body shape. The research in this paper provides a new reference path for clothing design innovation.

Forehead flap reconstruction for post traumatic nasal defects: functional and aesthetic outcomes

The nose being the central unit is an important structure with a social and psychological significance. The reconstruction of nasal defects is complex as it involves the reconstruction of three separate structural layers which should be properly restored to maintain a functional nasal airway and an acceptable appearance. In this study, the aim was to reconstruct the 3D contour, border, outline and symmetry of the nose in post-traumatic defects with a forehead flap cover. A prospective study was conducted in the department of plastic and reconstructive surgery, over 3 years, 20 patients with post-traumatic nasal deformity were included in the study. The defects were categorized based on the subunits involved. The parameters recorded were age, sex, mode of injury, existing co-morbidities, habit of smoking and alcohol, any previous scar on the forehead, and history of previous surgery. Twenty patients underwent resection, out of which 13 (65%) were males and 7 (35%) were females using a para-median forehead flap cover. The most common mode of injury was road traffic accident in 12 (60%) cases, followed by animal/human bite in 5 (20%) cases and sharp cut injury in 3(15%) cases. (50%) patients required an intermediate stage after 3 weeks in which flap thinning was done with or without cartilage placement. Complications included suture dehiscence in one case for which re-suturing was done. 60% of patients were very satisfied with the results, and only 1 patient was unsatisfied. The forehead flap is a reliable choice for reconstruction in post-traumatic defects due to excellent color and texture match. Immediate reconstruction can be done in all the patients after adequate debridement under antibiotic coverage. Full thickness defects including the lining can be easily addressed by folding the flap.

Application of single anterior teeth defect with computer-aided design and computer-aided manufacturing polymethyl methacrylate single-retainer resin-bonded fixed dental prosthesis in children

Objective: To explore the clinical effect of computer-aided design and computer-aided manufacturing (CAD/CAM) polymethyl methacrylate (PMMA) single-retainer resin-bonded fixed dental prosthesis (RBFDP) for single anterior teeth defect. Methods: A total of 14 children between 10-14 years old (male 8, female 6) who visited the Department of Pediatric Dentistry, School of Stomatology, The Fourth Military Medical University from March to December 2022 with single anterior teeth loss were enrolled in this study. The intraoral scanner was used to obtain their digital impressions, and then the data were imported into CAD software. The single-retainer RBFDP was designed by the CAD software and was manufactured by milling equipment using CAD/CAM PMMA disk. The prosthesis was then tried-in and bonded to the abutment teeth with resin cement and evaluated in a 12 month follow-up observation. The marginal discoloration, marginal adaptation, color match, secondary caries, the occurrence of fractures and loose of abutment tooth were examined on the basis of the modified United States Public Health Services evaluation system. The evaluation was divided into three scores, in which score A indicated ideal restoration effect, score B means that the restoration effect was acceptable (evaluation of restoration integrity, loose of abutment teeth and secondary caries excluded), and score C indicates that the restoration effect is not good. Results: All the 14 CAD/CAM PMMA single-retainer RBFDP had good marginal adaptation and color match with no marginal discoloration, no secondary caries, no fracture of restorations and no abnormal loose of the abutment teeth. All of the six criteria achieved score A evaluation after a three month follow-up observation. One restoration was classified as score B for fracture after a six month follow-up observation, while two restoration were classified as score B for marginal discoloration after 12 month follow-up observation. Conclusions: The CAD/CAM PMMA single-retainer RBFDP was clinically effective in restoration of single anterior teeth defect in children.

City Architectural Color Recognition Based on Deep Learning and Pattern Recognition

The collection of information about buildings and their colors is an important aspect of urban planning. The intelligent recognition of buildings using image information plays a significant role in the development of smart cities and urban planning. This thesis proposes a building color-recognition technique based on morphological features utilizing convolutional neural networks and the K-means clustering algorithm of image-recognition technology. The proposed method can identify buildings in images and classify them into two categories, buildings and panoramas, for color extraction and matching. This method involves training convolutional neural networks on deep learning so that the buildings can be differentiated and segmented. Subsequently, the K-means algorithm extracts colors from the segmented building images. The extracted building category, color, and text information were analyzed to obtain a comparison and analysis results of buildings and panoramas. The results demonstrated that the system is capable of accurately segmenting buildings, as well as extracting colors from both buildings and panoramas separately. It can also contribute to the extraction and presentation of color schemes in smart city planning and provide valuable insights for the future development of urban colors.

Color tuning halide perovskites: Optical amplification and lasing

Light emission with delicate wavelength control generates fundamental colors that are essential for vision-based applications such as displays, information communication, visual and augmented reality. Yet these light emitting technologies critically rely on the development of photonic sources for proper lighting and color matching. Halide perovskites have recently emerged as excellent and efficient photonic sources due to their outstanding photophysical properties, such as low defect trap densities, long carrier lifetime, large absorption coefficient, high quantum yield and optical gain. On a par with the rapid advances of light-emitting diodes (LEDs), perovskite-based optical amplifiers and lasers have made great strides in the past few years, which have much more accurate control of color-matched lighting, high power, spatial and wavevector control of color emission. In this review, we aim to review the recent progress of perovskite lasers at micro-, nano- and subwavelength scales, discuss the properties of halide perovskites and optical cavity structures that benefit color light emission, and examine the remaining challenges in the field for the future development of perovskite-based lasing technologies.

Survival and complications of 3D-printed, non-invasive restorations for prosthetic rehabilitations: A 12-month preliminary observational study.

The adjustment and transfer of a stable occlusion can be a major challenge in prosthetic rehabilitations. The aim of this study was to assess a non-invasive treatment option for complex prosthetic rehabilitations and occlusal analyses using 3D-printed restorations clinically. Eleven patients received a partial or complete rehabilitation with the aid of 3D-printed restorations (n=171). After 12 months of clinical service, all restorations were analyzed using the United States Public Health Service (USPHS) criteria. The 12-month clinical data revealed that 3D-printed restorations showed a survival rate of 84.4%. Complications occurred mostly regarding the anatomical form (7%) or marginal integrity (6AC%) and were consequently rated "Charlie" or "Delta." Color stability and color match of 3D-printed restorations were rated "Alpha" in 83% and 73%, respectively, of all restorations. Marginal inflammation was rated "Alpha" in 89% of all restorations. An excellent surface texture and no secondary caries or postoperative sensitivities (100%) were observed. 3D-printed restorations might be an alternative treatment option for initiating complex prosthetic rehabilitations. Technical complications rarely occurred. Biological complications did not occur at all. The color stability showed promising results after 12 months of clinical service. However, the results should be interpreted with caution. Long-term results with a high number of restorations should be awaited.

A step-by-step technique to create an ideal color match, form, and surface texture to all-ceramic restorations.

Although the presence of a chairside CAD/CAM system in the dental office saves time and cost, it deprives the dentist from the dental technologist' skills and experience. The dentist now has to gain and acquire knowledge and skills about how to finish, characterize, stain, and glaze ceramic restorations. The main objectives of this article is to teach novel and reproducible techniques for surface color, texture, glaze and polish for either the chairside or laboratory fabricated indirect ceramic restoration. A protocol for intraoral characterization of monolithic ceramics; the "Triple R" protocol for tooth color mimicking was followed. It consist of three steps: (1) "Recognize" tooth color shapes, (2) "Record" the present color shapes in the patient dentition by drawing a color map for the color shapes extension and determine which luster paste stain to be used for replicating them, and (3) "Replicate" intraorally the recorded color shapes guided by the adjacent natural teeth using low fusing ceramic pastes (shades and stains) for color shape replication. Also, the final touch technique was followed to shape, texture and final surface finish of dental restorations. It is composed of 5 basic levels which we call dental "micro-esthetics that define shape, texture, and surface luster. Following the steps of both; the "Triple R" protocol and the "FINAL TOUCH" technique will help to reproduce the final shade of the restoration to create the illusion of a natural tooth to the observer. This article shows how combining two practical methodologies to record and replicate both color shapes and surface texture of natural teeth may extend mimicking, that is, step by step natural tooth shade beyond the limitations of the available commercial shade guides.

The use of color elements in graphic design based on convolutional neural network model

Abstract Exploring the effective application of color elements in graphic design based on a convolutional neural network model is beneficial to promote the innovative development of the graphic design. Starting from the convolutional neural network, this paper defines the quantification of geometric features of graphic images by convolutional operation and pooling operation and uses pixel and spatial distribution for color element extraction. The global color features and local color features are used for color matching perception feature quantification, and then a graphic image design feature model is constructed, and the application analysis of color elements is carried out for this model. From the primary design color, the average selection rate of this paper’s model is 41.58%, which is 13.4% and 9.6% higher than that of the DCGAN and PLS-MLP models, respectively. From the keyword color quality generation, the color design results of graphic images have significant differences (p < 0.05). This indicates that the use of CNN-based graphic image design feature models can realize the effective application of color elements and also provides a new research direction for intelligent graphic design.

Interference of same/different learning by a spatial discrimination

Same/different learning by pigeons has long been of interest to experimental psychologists. In one of these procedures, matching-to-sample, responses to a sample stimulus result in the presentation of two comparison stimuli, one of which matches the sample, the other of which does not, and choice of the matching stimulus is reinforced. Evidence of a matching concept has been found when transfer has been found to new stimuli. Given the transfer results, it is surprising that acquisition of two matching tasks (or two mismatching tasks), has not been found to be any faster than one matching and one mismatching task (i.e., two compatible tasks do not appear to facilitate each other). In the present experiment, we asked if matching acquisition involving three colors would be retarded if the correct response to a fourth color was not matching but was spatial (e.g., if the sample is red choose the red comparison, if the sample is green choose the green comparison, if the sample is yellow choose the yellow comparison, but if the sample is blue choose the left comparison). We found that acquisition of this task was slower than acquisition of a four color matching task (i.e., when the sample was blue, the blue comparison was correct). The results suggest that there is an interaction among matching associations, such that common rules facilitate learning compared with having to learn an inconsistent (spatial) rule. This result provides further evidence of the development of a matching concept by pigeons.

Evaluation of Giomer Using Eighth Generation Bonding Agent and Resin-Modified Glass Ionomer Cement Restoration in Non-Carious Cervical Lesions.

Non-carious cervical lesions (NCCL) raise a considerable restorative challenge for the dentist in bonding, as adhesion is not as strong and predictable as enamel bonding. A critical factor for restorative success is the selection of restorative material. Clinicians have tried many restorative materials and techniques to obtain the best performance. The aim of the present study was to evaluate and compare the clinical outcome of a Giomer and Resin modified glass ionomer cement (RMGIC) restoration in NCCL using united states public health service (USPHS) criteria at baseline, 3, 6 and 12 months. Patients from age 25 - 50 years having non-carious cervical lesions on both the sides and requiring restorations were screened. 20 patients were selected and further divided into 2 groups using simple random sampling technique. Group A- Beautifil II restoration using G-Premio bond (n = 10) and Group B- Ketac N100 restoration (n = 10). Restorations were done according to manufacturer's instructions and consequently evaluated at baseline, 3, 6 and 12 months using the USPHS criteria for marginal discolouration, marginal integrity, surface texture, colour match, gross fracture and post-operative sensitivity. Giomer restorations showed better results than RMGIC. There was decrease in alpha ratings in both the study groups i.e., Giomer and RMGIC from 6 to 12 months. The overall findings suggest that both Giomer and RMGIC gave satisfactory clinical results when used to restore non-carious cervical lesions. Both the materials can successfully be used since there was no statistically significant difference in the clinical outcome.

Instrumental and visual evaluation of the color adjustment potential of a recently introduced single‑shade composite resin versus multishade composite resins

Single-shade composite resins simplify the process of shade selection by providing a narrow range of color but the ability to simulate all shades. However, evidence is limited for the color shifting ability of a newly developed single‑shade composite resin. The purpose of this in vitro study was to evaluate the instrumental color adjustment potential (CAP-I) and visual color adjustment potential (CAP-V) of a recently introduced single-shade composite resin compared with conventional multishade composite resins against different background colors. Four multishade composite resins (Spectrum TPH3, Beautifil II, Clearfil AP-X, and Gradia Direct) and a single-shade composite resin (Charisma Diamond One) were tested. Four base shades (A1, A2, A3, and A3.5) of the same composite resin (Filtek Z350XT) were selected as different background colors. Dual specimens (an outer base material with an inner hole filled with inner test material) and single specimens of all test and base materials were prepared (n=6 per group). Spectral reflectance values were obtained by using a spectroradiometer. The color difference (ΔE00) and relative translucency parameter (RTP) were calculated by using the CIEDE2000 and RTPCIEDE2000 formula. Visual scoring of color matching was performed by independent observers. The CAP-I and CAP-V values were calculated according to ΔE00 and visual scoring. Analysis of variance (ANOVA) was used for statistical analysis (α=.05). CAP-I and CAP-V were significantly affected by composite resin type, background color, and their interaction (P<.001). Positive CAP-I and CAP-V values were found for the majority of test materials. Charisma Diamond One exhibited the highest CAP-I value under all background colors, the highest CAP-V value under most background colors, and the significantly highest RTP value (P<.001). The color adjustment potential was dependent on the material type and background color. Charisma Diamond One exhibited the highest color adjustment potential and the most pronounced color shifting ability.
