Are you experienced in colour composition?!

OK, then have a good look at the following picture...

Are the colours of the

squares “A” and “B” the same?

NO?

Have a closer look!...

Not convinced?!

Go back if you want.

Nobody has changed the colour of the squares.

You have just witnessed an important

phenomenon about the funcion of the brain...

The brain interpretes the squares

as they should appear: Black or white,

shown here as a dark and light gray. It completely

disregards that they have the same shade! The

opposite squares suggest 2 different colours...

and your brain accepts this as a fact.

It shows that often we observe thingsnot as they are

but as we want them to be!
