Abstract:

In our study, we used virtual reality to examine how the color of an object's surroundings affects color constancy. We manipulated lighting and object properties in computer-generated scenes using Unreal Engine with jive different light sources, together with the virtual reality HTC Vive Pro Eye headset for visualization. Participants assessed color constancy by matching the target to a neutral reference among five differently colored objects in the scene. Our findings showed that color constancy performance drops significantly when considering illuminant colors in the opposite direction of the local surround color, revealing the interactive effects of surround color and illumination.
