Grey illusion

Here's an amazing optical illusion. The squares marked A and B on this checkerboard are the same shade of grey:

Don't believe me? Check out the rest of the article see if it's true.

I didn't believe it myself, so I snipped out the squares to compare them outside of the context of the checkerboard. Check out these details (zoomed 2x):

Pretty neat, huh?

Oy! It is TOO EARLY in the morning for a mind-bender like that. I am flummoxed! A good reminder though, pace St. Exupery, that "only with the heart can one see rightly."

St. Exupery is a nice reference, but Josef Albers is more pertinent. Those of us who suffered through Tony May's color theory classes will never forget the Bauhaus artists, Albers and Itten, who made our lives miserable for days without end as we mixed and remixed and remixed again to learn about the practical implications of relational color.

Hey, who would have thought that would pay off. Even in this context! Tony May probably doesn't remember me, but I bet he'd be pleased to know he made an impression.
