We can't know if anyone sees red the way you do. A researcher used quantum catch methods in monkeys to show how genes and eye color shape color perception, and your brain rewires itself based on what you've seen.
If you've ever wondered whether other people see color the same way as you, according to current scientific understanding, the percent chance that anyone else sees color the same way as you is essentially zero. We all see colors differently and I used to do research on this, so I'll tell you why. I used to work in a research lab doing something called a quantum catch, where we would take the genotype of the color detecting cells in different monkeys eyes and then we could map on a color plot how they would perceive fruits in the rainforest. And you could see how different monkeys would perceive the same color, fruit differently and humans are the same way. And genetic code is only one reason. The color of your eye, like brown versus blue, can also change how you see color. And our personal experiences can also shape how we perceive colors. Neural circuits in the brain that are involved in color processing can adapt based upon our experiences.
