Colors

This is something I think about from time to time. What if we didn't see the same colors? Sure we call them the same name, like green or blue or even purple. But what if my orange is your black and your yellow is my red? How would anyone ever know? What if it's true? What if no one else sees the world like I do? What if my beautiful red, orange, pink, and yellow sunset is someone's green, blue, teal, and aqua sunset? What if the sky isn't really blue?
