Color processing in the brain is a complex neural process that begins in the retina and extends to multiple brain regions. The sequence involves:
- Light activation of cone cells in the retina
- Signal transmission through the optic nerve to the lateral geniculate nucleus
- Processing in the primary visual cortex (V1)
- Further processing in the V4 color center of the brain
The brain combines this information with memory and context to create our final color perception. This is why colors can appear different under various lighting conditions or when surrounded by different colors (color constancy). The brain’s processing also explains why we can recognize colors even when lighting conditions change dramatically.
