Nice link. The first illusion is excellent and probably does have some affect on those who claim the sun is yellow while high in the sky. A slight majority favor a yellowish-white sun based on a poll conducted here. Hmmm, maybe it's time to bump it and get more opinions.
However, notice their error in the third illusion. If you mask the two center squares, one is lighter than the other.
