Different People's Brains Process Colors in the Same Way

Researchers at the University of Tubingen have discovered that human brains process colors in remarkably similar ways across different individuals. The team used fMRI scans from 15 participants viewing various colors to train a machine-learning model that could then accurately predict which colors a second group was viewing based solely on their brain activity patterns. Published in the Journal of Neuroscience, the study found that specific brain cells in the visual cortex consistently respond more strongly to particular colors across all participants. The discovery challenges long-standing philosophical questions about whether people perceive colors differently.
