Abstrakt: | Objectives: This multicenter study aimed to evaluate visual-instrumental agreement of six color measurement devices and optimize three color difference equations using a dataset of visual color differences (∆V) from expert observers. Methods: A total of 154 expert observers from 16 sites across 5 countries participated, providing visual scaling on 26 sample pairs of artificial teeth using magnitude estimation. Three color difference equations (ΔE* Results: The ΔE* Significance: Optimization of color difference equations notably improved visual-instrumental agreement, overshadowing device performance. The optimzed ΔE ' formula demonstrated the best overall performance combining computational simplicty with outstanding visual-instrumental agreement. (Copyright © 2024 The Authors.
