The figure above shows nothing more than a set of blinking magenta dots, but
if you stare at the cross for a few seconds, a green dot will appear
to fill in the gap. By staring at the cross even longer, the
magenta dots will completely dissappear, leaving only the green dot.
The new dot is green because green is the opposite (or complementary)
color of magenta. Try changing the color of the blinking set
of dots to discover what their opposites are.
