Three-dimensional stimuli and environment for studies of color constancy

Publication date: December 2019Source: Current Opinion in Behavioral Sciences, Volume 30Author(s): Yoko MizokamiWe perceive the stable surface color of objects even if the reflected light changes depending on illumination color. This perceptual property is known as color constancy. To understand color constancy in real life it is essential to conduct experiments within real three-dimensional (3-D) space. Color constancy is generally better and more stable for 3-D stimuli compared with two-dimensional (2-D) stimuli. Color, shape, and material properties are not represented precisely in a 2-D environment, such as images or patterns. Thus, there is missing information that may influence our recognition of objects and scenes. The critical factors for color constancy have not be conclusively identified. However, the combination of various cues present within the object and environment, and the recognition of space, illumination and objects, should contribute to establishing good and stable color constancy.Graphical abstractColor constancy in a real 3-D environment and various possible cues available in the scene contributing color constancy.
