This study investigates if the physical gamut correlates with realism judgments in natural scenes and finds that a real-world gamut better aligns with human perception than a theoretical model.

This study shows that optimal colors can predict luminosity thresholds in natural scenes, suggesting that physical gamuts encompass both self-luminosity and naturalness concepts.

This study investigates whether physical gamut theory applies to naturalistic stimuli, finding it valid for natural objects in realistic scenes and showing that luminosity thresholds are influenced by both self-luminosity and naturalness.

This study investigates how object shape cues and top-down factors influence translucency perception in rich environments.

This paper introduces a method for calibrating VR HMD colors using Three.js and evaluates three HMDs, finding the HTC Vive Pro Eye performs best.
