Impossible colors



Residing in the visual cortex of our brain, the two opponent neurons function in a binary way: red-green opponent can signal either red or green, while blue-yellow opponent signal either blue or yellow. These neurons cannot signal both the colors at a time. The neurons won’t let you see blue and yellow at a time nor red and green, the combination of which is known as impossible colors.
