This raises multiple questions on how to measure color of 3D translucent objects, how to describe their color appearance, and how to quantify color differences among them. Or are these ill-posed problems in the first place? We discuss the first steps on this topic and suggest the future directions for color and appearance research.Attribution 4.0 International LicenseCategories and Subject Descriptors (according to ACM CCS): I.3.6 [Computer Graphics]: Methodology and Techniques- -Standards J.4 [Social and Behavioral Sciences]: PsychologyI.3.6 [Computer Graphics]Methodology and TechniquesStandardsJ.4 [Social and Behavioral Sciences]Psychology10.2312/mam.202411754 pages
