Color perception
The term color perception is how we experience the hue, saturation and brightness of a color. The manner in which we organize our experience of color must have a correlate with neural activity at some level of the visual system, so the manner in which the information is sampled, integrated and transmitted in the visual system should be related to the representation of color. The historical broad usage of the term color to refer to physiological or physical properties and events, rather than to perceived phenomena, is a common misconception and source of confusion.

As we progress through the visual system, the receptive fields expand to encompass larger portions of the visual field. This suggests that at later stages of visual processing, the responses of cells are influenced by events occurring at locations further away from the centers of receptor fields. For example, the colors that we attribute to lights and surfaces are highly dependent on the spatial, temporal and chromatic properties occurring elsewhere in the visual field. Therefore the neural processes mediating color perception are intertwined with those in object perception.

Depth perception
Identifying the spatial layout of the variety of different objects and surfaces that make up our surroundings is a crucial goal of depth perception. The perception of depth is actively organizing the depth estimates into meaningful sections. To determine an inconsistency of an element, the element must be localized in the visual system in two retinal images. Once the matching image features have been identified, the difference in retinal location is the retinal disparity,which can be utilized to estimate depth.
