Naturally I have wondered that if the purple I see, is the same purple you see when we are looking at the same flower. Obviously we can both agree that the flower is purple, but the complexity of something like the eye and the brain working in tandem to create an image in my mind makes me think that there has to be variation from person to person on the hue, tone, and quality of color of the same flower. Turns out I am not the only person to contemplate this.
Radiolab (a.k.a. my 2nd favorite radio show) did a whole episode on color. They talk about that very thing. Is color something created by our perception and interpreted by our brains or is it something independent and outside of us? Turns out it’s both.
dogs – 2 cones
humans – 3 cones
butterflies – 5-6 cones
mantis shrimp – 16 cones
I really wish I could see what the mantis shrimp sees, at least for a few minutes.
They also discuss the evolution of color through literature starting with the Odyssey. It’s freaking cool. But I won’t say any more, you have to check it for yourself. LISTEN TO THIS EPISODE here. You're welcome.
