An individual with only M-cones:
A) is sensitive to changes in the wavelengths of light but not the intensity.
B) can achieve metameric color matching with only certain wavelengths of light.
C) can achieve metameric color matching by adjusting the intensity of light.
D) cannot perform metameric color matching.

Question

Quizplus · Accepted Answer

Individuals with only one type of cone, such as M-cones, can still achieve metameric color matching by adjusting the intensity of light. This is because metameric matching involves matching the perceived color of different light sources by adjusting variables such as intensity, even when the spectral compositions are different. Without the ability to compare different wavelengths via multiple cone types, adjusting intensity is a method to achieve a form of color matching.
