In 1872 German physiologist Ewald Hering suggested that color vision was based on opponency between red and green and between yellow and blue; at each spot in the visual field, the redness and ...

In a separate experiment, the researchers found that this color-opponency system did not work for memories. They presented the same participants with pictures of objects that a color is commonly ...

This finding suggests that color opponency, which is responsible for cancelling out certain hues (red versus green, blue versus yellow and black versus white) of color, can be disabled ...

The result is a color signal that travels back to the brain ... The diagram revealed different patterns for the red /green opponency and the yellow/blue opponency, and provided new information ...
