Suppose you perceive something as red. According to the trichromatic theory, what is the explanation? a. Light from the object has excited your long-wavelength cones more strongly than your other cones. b. Light from the object has excited your short-wavelength cones more strongly than your other cones. c. Ganglion cells that increase response to red and decrease their response to green are firing strongly. d. Ganglion cells that increase their response to green and decrease their response to red are responding weakly.
