I believe in purple.

After you get done exploring how we perceive colors associated with different wave lengths of light, and how nobody really knows whether these are common somehow, or unique to each of us, that sentence should bring you both a chuckle and some wonder about perception.

From the physiological standpoint human individuals are far, far from being unique. The electrochemical reaction of a neuron in the cortex which indicates the perception of ‘red’ is pretty much the same in any human (and not only).

Whether that subjective perception is the same remains unknown. We have no solid way to communicate any of that yet.

I am inclined to believe it is, but we do not really know.
