Claims about private color perception

“I would say recent experiments lead us down a road to the idea that we don’t all see the same colors,” Neitz said.

One person’s red might be another person’s blue and vice versa, the scientists said. You might really see blood as the color someone else calls blue, and the sky as someone else’s red. But our individual perceptions don’t affect the way the color of blood, or that of the sky, make us feel.
