Hey Roger,
The threshold of differentiation is, I suspect, different for different
people, taking into consideration the brain as "computer" or perceiver
and the eye as camera or sensor. Environment will also be a big
factor--or how the colors are presented: two patches close in color
next to each other will be more easily distinguishable that those colors
presented amongst other disparate colors.

David,
It comes back to my "idea" of "threshold"; what's the 'criteria' that makes two colors
appear "different" to a 'normal observer'? It has to be 'measurably' different otherwise, we're
going to argue until the cows come home.

Hi Andrew,
My point was that when there are colors separated by an extremely small
increment, they may be indistinguishable from each other and we may may
perceive them to be the same color--so not invisible but visible--just not
perceptually different. Seems like we are making two different valid arguments.
