Subject: Re: a link to some interesting illusions
Very interesting!
Skeptics should be shown the RGB values of relevant pixels, by using
PhotoShop, or other viewers which show this info.
I suspect the striking success of Illusion #2 capitalizes on the fact that
"brown" is not a spectral color and so is more subjective in character -
depending greatly on surrounding colors.
