In perception research, the memory color effect is cited as evidence for the opponent color theory, which states that four basic colors can be paired with its opponent color: red—green, blue—yellow. This explains why participants adjust the ripe banana color to a blueish tone to make its memory color yellow as gray. [10]
Visual memory occurs over a broad time range spanning from eye movements to years in order to visually navigate to a previously visited location. [1] Visual memory is a form of memory which preserves some characteristics of our senses pertaining to visual experience.
Color vision is categorized foremost according to the dimensionality of the color gamut, which is defined by the number of primaries required to represent the color vision. This is generally equal to the number of photopsins expressed: a correlation that holds for vertebrates but not invertebrates .
Visual perception is the ability to interpret the surrounding environment through photopic vision (daytime vision), color vision, scotopic vision (night vision), and mesopic vision (twilight vision), using light in the visible spectrum reflected by objects in the environment.
It coexists with VSTM but unlike it visual stimuli can overwrite the contents of its visual store. [21] Further studies suggests an involvement of visual area V4 in the retention of information about the color of the stimulus in visual working memory, [22] [23] and the role of the VO1 area for retaining information about its shape.

The visual hemifield contralateral to a lesion in the lingual or fusiform gyrus is the one that appears grey, while the ipsilateral visual hemifield appears in colour. [13] The variance in symptoms emphasizes the need to understand the architecture of the colour centre in order to better diagnose and possible treat cerebral achromatopsia.

Close up of the human eye, where vision begins. Visual memory describes the relationship between perceptual processing and the encoding, storage and retreival of the resulting neural representations. Visual memory occurs over a broad time range spanning from eye movements to years in order to visually navigate to a previously visited location. [1]
