Eye

As a sensory organ for the perception of light and color, the eye absorbs light stimuli through photoreceptors. These stimuli are processed by the brain into optical perception. The human eye contains rods in the retina for detecting light/dark contrasts and cones for color perception (blue, red, green). These signals are then processed by the brain into subjective color experiences. Individual color perception varies with factors such as gender, nationality, and age, and is also influenced by ambient light. As a result, color determination remains a subjective experience.
