According to the trichromatic theory of color vision,
A) the brain separates images into "either-or" messages of red-green, blue-yellow, or black-white.
B) there are three types of rods, each sensitive to either yellow, red, or blue.
C) the eye has color receptors that are limited to white, black, and red.
D) there are three types of cones, each sensitive to either red, green, or blue.

Question

Quizplus · Accepted Answer

The trichromatic theory of color vision proposes that there are three types of cones in the eye, each sensitive to a different range of wavelengths. These cones are primarily sensitive to red, green, and blue light, and they work together to allow us to perceive a wide range of colors. This theory is supported by research on the physiological properties of the eye and provides a basis for understanding color mixing and color blindness. Choice A is incorrect because the trichromatic theory does not propose an "either-or" system for color perception. Choice B is incorrect because rods are not involved in color vision, and they do not have specific sensitivities to colors. Choice C is incorrect because the eye has color receptors (cones) that are sensitive to a range of colors, not just white, black, and red.
