Hal has talked about how the brain compensates to build a proper white balance and I have to deal with this issue maybe a bit more than others.

I had cataract surgery a couple years ago now on my left eye. The new intraocular lens left me with 20/40 vision and a perfectly clear lens. My old, biological lens in my right eye is noticeably yellowed, (and gradually degrading into cloudiness that will require replacement).

I find to really "see" color accurately, I have to close my right eye.

Another aspect of the two different lens "tints" is that if I look at something through a railing, like a white house, I will see white in my left eye, and more of a yellowish white in the right eye, both at the same time. Brain wern't wired up for that!

Anyway, my contribution to the foibles of brain/eye interaction in building colors.
