Color processing is a complex interaction between the eyes and brain:
- Light enters the eye and stimulates cone cells
- Signals travel through the optic nerve to the visual cortex
- The brain processes these signals in specialized areas
The brain’s color processing center (V4) combines information about wavelength, intensity, and context to create our perception of color. This explains phenomena like color constancy – how we perceive an object’s color as consistent despite changing lighting conditions. The brain also influences color perception through memory and experience, which is why different cultures may categorize and name colors differently.
