Really? And what can we learn about the color _in the brain_ from a study 
of photons and wavelength?
Dammit....
Functional Magnetic Resonance Imaging allows the study of the working 
brain.
Color is of course an element of that reality that put us all here. Our 
perception of it is of course in the brain. But you must grant that what 
is color out there is not the perception of it. That truth is 
self-evident.
And while a study of photons and wavelength provides us with some 
knowledge about how the eye itself works, only fMRI and its cousin 
techniques provide us with studies of the working brain.
Is not the study of perception a core pursuit? From somewhere inside my 
slumber I think it is....
