Not sure where this should go -- will this be an entry on color as part of the visible spectrum of light, on the biology of color reception by the human eye or brain, or color in the arts? Russell Potter 08:33, 13 June 2007 (CDT)

I think all three! I plan to discuss pigments, how it's produced in various materials, use; but also elaborate more on the scientific process behind it. There's lots of work to do.--Robert W King 08:32, 13 June 2007 (CDT)

The funny thing is, I was just about to add biology, but someone beat me to it. Greg Woodhouse 14:56, 13 July 2007 (CDT)

This segment:

"The wavelngth of monochromotic light (or of an individual photon) falls into a continuous range of about 400 to 750 nanometers. We split this range up into seven colors because they correspond well to the way we see light."

I agree it's an integral part of the article but where it currently stands is a little out of place; it does not "flow". Perhaps it should go into the introductory paragraph?--Robert W King 11:52, 15 July 2007 (CDT)

I added it where I did because I wanted to clarify the statement that light is divided up into seven colors. it probably should be moved up, but then the section on the spectrum (which is misnamed) also needs to be rewritten a bit. At any rate, I was trying to be as nonintrusive as possible. Greg Woodhouse 12:21, 15 July 2007 (CDT)

I'm not implying you're intruding ;). I welcome any and all feedback; I just wanted to know where you thought it should go and what needs editing for readership context.--Robert W King 12:31, 15 July 2007 (CDT)

Biology of rods and cones

I think the section

The capability for these cone receptors to absorb different wavelengths exists because of the pigments within them: a transmembrane protein called opsin which binds to the prosthetic group retinal, a type of Vitamin A. Rods employ a different kind of pigment called Rhodopsin, which is in the membrane of the outer section.

is inaccurate, or at the very least, misleading. I think a more accurate (if less poetic) description of photoreceptors would be appropriate. Greg Woodhouse 12:31, 15 July 2007 (CDT)

I confess, I wrote that with the intention of expanding it out at a later point, but I haven't and I agree that it comes up short. --Robert W King 12:32, 15 July 2007 (CDT)

Should be improved now, simplified and more meaningful, but still incomplete.--Robert W King 13:14, 15 July 2007 (CDT)

Newton's prism experiment

There probably ought to be some mention of Newton's prism experiment, too. Greg Woodhouse 15:38, 15 July 2007 (CDT)
