Colour

 Goethe's Colour Wheel

What is colour? Is it intrinsic to the object or a creation of neural processing? An article I found here entitled Colour Plays Musical Chairs In Our Brain intrigued me. 

"One view," says Noë, "is that color is a property of the surfaces of objects, not the property we naively think we see, but maybe something like a disposition to absorb and reflect light of certain wavelengths... another view is that... color happens to us. The leaves in the tree are not green. Greenness is just something that happens. In me it’s a kind of sensation that is produced thanks to the activation of my nervous system by those leaves." 

 So, what do you think? What is colour, anyway?
