red–green responses

a concept of color vision in which certain retinal cone receptors have excitatory responses whereas others have inhibitory responses to the same wavelength of light. Because red and green are at opposite ends of the spectrum, it is assumed that a red excitatory response is accompanied by a green inhibitory response.
