I recently posted an Article on 'We Have more colors Than we See'.
I mentioned there that there are infinite colors and we see only seven because of our limitations.
I found an interesting article on the same subject to-day.

It provides the entire field of view. By contrast, our eyes can only see a narrow angle ahead of us, and the images they form are only sharp at the very center of our visual field.
