1 Colour selection Green and orange appear to have no link with the design of the flag. When observing a colour wheel, however, you’ll see the tones have in fact been carefully selected. Facing green on the wheel lies red, while facing orange is blue. This makes them opposite colours. 2 Stare out When you look at something, specific colour receptors in your eyes are stimulated based on the tones of the object in front of you. As you stare at the colours in this picture for an extended period of time, the receptors recognising green and orange become fatigued and less responsive to that colour of light. 3 Fresh vision As your eyes look away, these visual receptors are able to rest, stimulating the unused receptors. The opposite colours are produced briefly as a result, which in this case are blue and red, showing the true flag. 4 Background selection The plain background helps you to see the afterimage. The image remains in your eyes for a while due to the overstimulation that’s caused by staring for so long at the bright inverted image. 5 Fade away This afterimage illusion will remain for around 30 seconds before your eyes’ photoreceptors readjust to normal stimulation.
