He then places it behind his back again and then chooses to reveal just one of the two balls, picking one of the two at random with equal probability. Next, he takes one of the balls and brings it out from behind his back and displays it. You give the two balls to your friend and he puts them behind his back. You want to prove to him they are in fact differently-coloured, but nothing else in particular, you do not want to reveal which one is the red and which is the green ball. To your friend they seem completely identical and he is skeptical that they are actually distinguishable. Imagine your friend is red-green colour-blind (while you are not) and you have two balls: one red and one green, but otherwise identical. One of these involves two differently-colored balls and a color-blind friend.
