Evidence that some cones are especially sensitive to red light,others to green light,and still others to blue light is most directly supportive of

A) Weber's law.
B) the Young-Helmholtz theory.
C) accommodation.
D) the opponent-process theory.

Young-Helmholtz Theory

A theory of color vision proposing that the eye contains three types of receptors sensitive to red, green, and blue, which can produce the perception of all colors through their combined activity.

Especially Sensitive

Referring to individuals or systems that react more intensely or quickly to stimuli or changes in the environment than is typical.

Cones

Photoreceptor cells in the retina of the eye that are responsible for color vision and function best in relatively bright light.
