In black you can read the word GOOD, in white the word EVIL (inside each black letter is a white letter). It's all very physiological too, because it visualize the concept that good can't exist without evil (or the absence of good is evil )
The word TEACH reflects as LEARN.
Can you see why this painting is called optical illusion ? You may not see it at first, but the white spaces read the word optical, the blue landscape reads the word illusion. See for yourself !
In brown you can read ME, and when you look through you can read YOU.
