Verified step by step guidance

Understand that the human eye contains photoreceptor cells called cones, which are responsible for color vision.

Recognize that there are three types of cones, each sensitive to different wavelengths of light, corresponding to different colors.

Identify that the three types of cones are sensitive to red, green, and blue light. These are the primary colors of light in the context of human vision.

Note that the combination of signals from these three types of cones allows us to perceive a wide range of colors through a process called color mixing.

Remember that this trichromatic theory of color vision explains how the human eye perceives color by combining the input from the red, green, and blue cones.
