Answer 1

The opponent-process theory of vision explains that an individual's capability to see color is controlled by three types of receptor with opposing mechanisms. These three receptors - red-green receptor, blue-yellow receptor, and black-white receptor.The opponent-process theory described that these cells can only perceive the one color at a time because these two colors are opposite to each other. For example- People can perceive only one colour out of greenish and red because these opponent cells could perceive one colour out of these colors at a time.

The opponent color process occurs via a mechanism of excitatory and inhibitory actions, with the two aspects of each mechanism are opposite to each other.

Such as red creates a excitatoryresponse, while green creates a inhibitory response. These responses of cells are managed by opponent neurons. Opponent neurons means neurons that have an excitatory response to some wavelengths and an inhibitory response to wavelengths in the opponent part of the spectrum.
