Is your red my red???

Is your red my red ??? Its a question  philosophy students are frequently confronted with. When you and I look at the same red object and we both agree it's red , how do we know we're experiencing the same color?  what you experience as red can be my green. It's a fascinating question since there are so many ways to look at it. 

Most scientists would have answered that people with normal vision probably do all see the same colors. The thinking went that our brains have a default way of processing the light that hits cells in our eyes, and our perceptions of the light's color are tied to universal emotional responses. But recently, the answer has changed.

"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.

Its Impossible to know but it's an interesting question and might answer why we like different colors. We can agree on that an object is red but we might perceive the  colors differently.

Scientists believe that color perception may not be predetermined like many have believed for hundreds of years.
