This paper proposes a perception-guided HDR-to-SDR framework that combines tone mapping and color correction using perceptual supervision from a cross-media appearance-matching experiment. In the experiment, color-chart patches were presented under three illuminance levels (50, 1000, and 35 000 lx), and observers adjusted their perceived appearance on a calibrated wide-gamut SDR display. The collected data showed good observer consistency, with mean <span></span><math>\u0000 <semantics>\u0000 <mrow>\u0000 <mo>∆</mo>\u0000 <msub>\u0000 <mi>E</mi>\u0000 <mn>00</mn>\u0000 </msub>\u0000 </mrow>\u0000 <annotation>$$ Delta {E}_{00} $$</annotation>\u0000 </semantics></math> values of 1.4 and 3.4 for intra- and inter-observer variation, respectively. Based on these data, a compact tone-compression model was developed using a shared power-law mapping parameterized by adapting-white luminance and applied locally through pixel-wise white estimation. In addition, an appearance-guided colorfulness correction was introduced to reduce colorfulness drift while preserving hue stability. Quantitative evaluation on two benchmark HDR datasets, comprising 105 images from Fairchild's HDR Photographic Survey and 457 images from LVZ-HDR, showed that the proposed method performs competitively in terms of TMQI, FSITM, and HDR-VDP-3, indicating strong performance in both fidelity and perceptual quality.</p>\u0000 </div>","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":"51 3","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148089352","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}

Lindsey","doi":"10.1002/col.70087","DOIUrl":"https://doi.org/10.1002/col.70087","url":null,"abstract":"<p>Researchers studying color naming and categorization often face challenges in integrating their results across different studies that employ different stimulus color samples. While the Munsell Book of Color (MBC) is predominant, many studies use the more accessible Color-aid Corporation (CAC) samples—either the “Standard Set” of the Color-aid system (CAC-220), used in 1948–1989, or the “Full Set” (CAC-314), introduced in 1989. To facilitate cross-study comparisons, we measured 65 color samples from CAC-220 and 67 color samples from CAC-314 sets that were used in earlier studies. We performed measurements in two independent laboratories, using different calibration devices, but under nominally identical D65 illumination. We determined colorimetric properties of those color samples in CIE <i>xyY</i>, <i>Lab</i>, and <i>LCh</i> color systems and established correspondences with the World Color Survey (WCS) palette, derived from MBC. Results demonstrate acceptable correspondence between most CAC-220 and CAC-314 samples (average CIE 76 a*b* ΔE = 3.62), with only six samples showing larger differences. We successfully matched 55 of 67 CAC-314 samples to the WCS palette by visual inspection, providing a bridge between studies using different color sets. Inter-laboratory measurements showed good agreement (ΔEs = 2.70–4.26). However, our calibrations differed substantially from previously published CAC measurements (ΔEs = 11.67–12.70). Sample copy variation, illuminant differences, manufacturing changes, or sample aging might explain some of the differences. Overall, our conversion tables should enable researchers to translate between color systems, compare results from studies using different color sample sets, and establish reproducible methodologies, enhancing past and future comparability in color cognition research.</p>","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":"51 3","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/col.70087","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148086157","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}

The methodology employed two psychophysical experiments using 24 stimuli consisting of glass, metal, and stone. The first was a direct comparison of the perceived gloss between the real objects and their initial colorimetrically reproduced images. The second was a selection task where participants matched the gloss of the real objects to a set of algorithmically processed images. The findings reveal two key results: (1) The direct comparison demonstrated that digital colorimetric reproduction significantly reduced the perceived gloss compared to the real objects. (2) The subsequent image selection experiment indicated that the contrast component of gray level co-occurrence matrix (GLCM) features is a significant predictor of the accuracy in reproducing the real objects' gloss. These results suggest that accurate gloss reproduction in digital displays is not solely dependent on colorimetric fidelity, but can be effectively achieved through the modulation of image contrast.</p>\u0000 </div>","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":"51 3","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668439","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}

Considerable efforts have been devoted to developing methods that more accurately estimate the illuminant color, typically aiming to minimize the angular error between the ground-truth and estimated illuminants. The results of this study suggest that focusing solely on reducing angular error may not be optimal, given the practical variations in ground-truth illuminants and the mismatch between angular error magnitude and the overall perceived color appearance of the processed image. Instead, minimizing the chromaticity shift between the estimated and ground-truth illuminants perpendicular to the blackbody locus appears to be a more effective alternative to angular error.</p>","PeriodicalId":10459,"journal":{"name":"Color Research and Application","volume":"51 3","pages":""},"PeriodicalIF":1.4,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/col.70084","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147668260","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}

With the development of HDR display and imaging technologies, the characterization of the perceptual attributes of highlight stimuli with the luminance beyond the diffuse white luminance is becoming important. None of the existing UCS or CAM (i.e., CIELAB, CIECAM02, CAM02-UCS, IPT, ICtCp, and hdr-CIELAB), however, was developed for such purposes. In this study, we carefully designed three experiments to investigate the lightness and chroma scales of highlight stimuli in HDR scenes. The results clearly suggested the poor performance of these models, especially the overestimation of the chroma for highlight stimuli.
