Question 18 (1 point) The trichromatic theory of color vision proposes that the perception of color O a) occurs when cones respond selectively to certain ranges of light wavelengths b) results from cones responding in a stimulate/inhibit fashion to specific pairs of colors is the process of cones responding selectively to certain ranges of light wavelengths but in a stimulate/inhibit fashion to pairs of colors c) O d) is much like mixing different colors of paint to achieve a single color that is new

Explanation / Answer

Option A The first, trichromatic theory, is based on the idea that the visual system is maximally responsive to three colors and that color vision is a result of the combination of differential responses of these three components. As evidence for the theory, proponents cited the fact that all the colors that can be perceived can be created by mixing three colored lights that differ in wave length. All you have to do is to differentially vary the intensity of the three lights, so long as they are different wave-lengths (colors), and you can get the three of them to mix to display virtually any color. There are three receptors in the retina that are responsible for the perception of color. One receptor is sensitive to the color green, another to the color blue and a third to the color red. These three colors can then be combined to form any visible color in the spectrum. The three different cone receptors are:- Short-wavelength cone receptors, Middle-wavelength cone receptors, and Long-wavelength cone receptors.
