The fact that a person with normal color vision sees yellow when both red-sensitive and green-sensitive cones are stimulated simultaneously is most directly supportive of the Young-Helmholtz theory, which states that color perception is based on the activity of three different types of cones- red-sensitive, blue-sensitive, and green-sensitive cones. This theory suggests that stimulation of both red-sensitive and green-sensitive cones simultaneously can create the perception of yellow.
