Color processing is a complex neural process that occurs in multiple stages:
- Light enters the eye and stimulates cone cells in the retina
- These cells convert light into electrical signals
- Signals travel through the optic nerve to the visual cortex
- The brain processes these signals in the V4 region
Interestingly, color perception isn’t just physical – it’s also influenced by psychological factors. The brain can adjust color perception based on context, lighting, and memory. This explains phenomena like color constancy, where we perceive objects as having the same color under different lighting conditions, and why colors can affect our emotions and behavior.
