Fortezza da Basso—a large, fortified complex consisting of old and new buildings—is the main venue in Tuscany for international exhibitions and cultural activities. In 2010, the Municipality of Florence started its restoration, which is still ongoing. The goal is to renovate the Renaissance parts of the fortress and replace the 20th-century pavilions with environmentally sustainable buildings, harmonically integrated in the context. The renovation started with a project aimed at assessing the preservation status of the fortress. In 2016, the Municipality of Florence developed a body of design rules, the “Fortezza System,” dedicated to the design of new buildings within the fortress. A key role was assigned to CMF design: at first, to identify the fortress CMF identity; then, to develop CMF prescriptions to harmonically integrate the new constructions with the historic parts. The CMF approach required for such an ambitious plan also had to be flexible and with wide design margins to allow architects experiment innovative CMF languages. Such conflicting needs were met by designing a CMF approach based on Chromatic Areas, that is, usable continuous areas in the color space rather than on color charts based on lists of allowed historical colors. The article shows how the developed CMF approach can contribute to the full preservation of the Fortezza historical identity and at the same time increase the autonomy of architects in their material and color choices.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140115222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was reported that reddish skin was matched with a higher lightness scale stimulus than yellowish skin among Japanese observers. However, this trend is inconsistent among Thai, Korean, Chinese, and European observers, implying the influence factors, such as ethnicity, environment, and judgment criteria. In this study, we investigated the influence of the experimental method on facial brightness perception using test stimulus images with constant lightness and different hue angles. We examined two instructions (“Appearance match” vs. “Brightness match”) and the scale stimulus for matching (a uniform color patch vs. a face image). We further conducted an impression evaluation experiment of the whole face. The matching results from the Japanese showed a similar trend in both instructions and scale stimuli under most conditions, suggesting that matched brightness is not influenced by instruction and the complexity of scale stimuli. The impression evaluation results were similar for Thai, Japanese, and Chinese observers, with reddish faces being evaluated with higher scores in brightness. Our findings suggest the influence of experimental methods on facial brightness judgment. The holistic judgment of facial brightness would be universal among different East Asian groups, at least for the range of variation in skin color we used.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139956842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study conducted a psychophysical experiment to investigate the association between lipstick colors and the impressions they create. Thirty-five observers were invited to participate in the experiment. They were asked to assess 20 lipstick colors on 23 impression scales. The results showed that the impressions created by the lipstick colors comprised three factors: charm, cuteness, and contemporary. Charm was correlated with a* and lightness value of lipstick color and the color difference between lipstick-skin colors. Cuteness was negatively correlated with the hue angle of the lipstick colors and lightness differences between lipstick-skin colors. Contemporary was correlated with chroma differences and negatively correlated with b* of lipstick color. These lipstick colors can be classified into three groups based on impression factors. The results showed that a* value of lipstick color and the color difference (<math>\u0000 <mrow>\u0000 <mo>△</mo>\u0000 <mi>E</mi>\u0000 </mrow></math>) between lipstick and skin color are identified to determine the grouping of lipstick colors.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139945434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within teacher education, this is particularly crucial, as these early conceptions can deeply influence how future educators understand and teach these concepts, highlighting the need for an approach that weaves these initial understandings into a coherent scientific framework. Instructing students on color concepts reveals that many grapple with the fundamental optical principles. These initial understandings are integral to designing educational sequences that facilitate conceptual evolution, allowing for a deeper grasp of scientific ideas. This study aimed to examine and interpret the initial conceptions that aspiring primary and secondary educators hold about color and its optical fundamentals, while also developing and applying virtual teaching resources to promote a conceptual change about these foundational concepts. A quasi-experimental approach was employed, comprising control and experimental groups, and utilizing both qualitative and quantitative methods for a comprehensive analysis. Engaging 409 trainee teachers through non-probabilistic sampling, the study stratified participants by degree program. These groupings facilitated a comparative evaluation of the pedagogical efficacy of the educational resources developed. The study utilized an online assessment comprising single-answer multiple-choice questions, grounded in prior research, which was psychometrically validated. Educational tools were then developed and implemented to foster a deeper understanding of color concepts among prospective teachers. Results analysis highlighted the existence of preconceptions about color among participants from diverse educational backgrounds. The interventions employed were effective in catalyzing a shift in conceptual understanding and in elevating the knowledge levels of the trainee teachers.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139518675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Boster concluded that both the unfolding of color piles in a sequential color sorting task and the unfolding of color terms according to Kay and McDaniel's model reveal how human beings understand color. If this is correct, then: (1) pile sorts should be reasonably robust across variations in the palette of colors to be sorted, as long as the palette contains good examples of Berlin and Kay's universal color categories, and (2) pile-sorting should be more related to lexical effects and less related to perceptual processes governed by similarity judgments alone. We report three studies on English speakers and Somali speakers (Study 1 only), where participants sorted colors into 2…6 piles. The three studies used varying numbers of palette colors (25, 30, or 145 colors) and varying chromaticity schemes (mainly hue, widely-separated in hue and lightness, or densely distributed at high chroma). We compared human sorting behavior to Kay and McDaniel's model and to the “optimal” patterns of color sorting predicted by Regier's well-formedness statistic, which quantifies the perceived similarity between colors. Neither hypothesis is confirmed by the results of our studies. We propose that color sorts are determined by pragmatic influences based on heuristics that are inspired by the palette of colors that are available and the task that the viewer is asked to perform.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/col.22918","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139094566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the conversion method from CIE-XYZ color system to DIN color system consists of the DIN 6164 method combined with the manual reading method. However, the DIN 6164 method cannot be used for the edges of a chromaticity diagram. The manual reading method can read all areas in a chromaticity diagram; however, it is too inefficient to convert large quantities of data. This study builds on the manual reading method to create a new method entitled the program reading method. Upon comparing the relative error, absolute error and conversion times of all methods, it was determined that the program reading method achieved higher accuracy than that of the manual reading method. The maximum relative error of the program reading method was 3.24%; however, the conversion time for each sample was 0.07 s, which was 3.5 times slower than that of the DIN 6164 method. Based on these findings, this study proposes an automatic conversion method that combines the strengths of both approaches: the DIN 6164 method to be used for interpolable areas and the program reading method to be used for areas that cannot be interpolated. The automatic conversion method outlined in this study provides an efficient, precise and fast way to convert a CIE-XYZ color system to a DIN color system.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138743537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The original methodology was therefore extended across 10 linked sub-experiments to make comparisons between some 36 gamuts, which were designed to exhibit a variety of different gamut shapes, contrast ratios, and substrate colors within the constraints of a desktop display. In addition to each set of test images, a common normalization set was included in all sub-experiments in order to adjust each observer's choice of modulus to a global average observer, and thus combine the results into a larger data set. Finally, an interval scale was inferred from the normalized magnitude data using a categorical judgment approach to calculate scale values.

Specifically, alkali-based pigments, commonly used as spot colors, are carefully formulated to ensure consistency across production batches. The presence of OBAs, which absorb ultraviolet light and emit it in the visible spectrum, significantly affects color perception and accuracy on paper when interacting with these inks. This research marks an initial investigation into how OBAs in paper influence the color accuracy of five distinct alkali-based spot color paste inks using a Little Joe ink proofer. The research examines the physical, optical, and colorimetric characteristics of two paper samples-one with OBA and one without- and analyzes the colorimetric changes occurring during the ink drying process. The results indicate that reflex blue, purple, and violet spot colors achieved acceptable delta E (ΔE00) value of below 3 on non-OBA paper, with rubine red being on the borderline at 3.1 after 48 h. In contrast, purple, rhodamine red and violet achieved acceptable ΔE00 below 3 on high OBA paper. The distinct behavior exhibited by certain inks led to the conclusion that achieving a consistent proofing procedure across diverse alkali-based ink formulations is impractical.","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":null,"pages":null},"PeriodicalIF":1.4,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/col.22914","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138525045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although AI exhibited prowess in replicating established design parameters, the study underlined the importance of critically assessing its outputs. The quantitative analysis illuminated overarching similarities in primary color selections. However, the AI's diversity in color remains less concentrated than that of human, suggesting a gap in the AI's capacity to match human expertise in color proportioning and distribution. As AI continues to evolve, it is crucial to discern its capabilities and potential limitations in the design domain, ensuring it augments human creativity rather than supplanting it.
