Flag Optical Illusion - China Poster

Senario: "An alien who has landed on this planet can only see the colours as different shades of pink. She discovers a new colour by observing the flags of different countries, namely the Green colour. She knows immediately this is a sign from her planet, showing her what is her mission on planet Earth. The message was namely: ' Turn all the flags into Green and then get rid of them altogether ' ..." Optical Illusion: There exist no green colour in this flag whatsoever. The viewer should first use the magnifier (View a larger image.) Now to turn the stars in the flag into a bright green colour, the viewer should completely ignor the stars and watch the right side of the image for a while, counting to 50 (just as an example.) Now looking at the whole image will turn the stars into fully bright green. The longer the observation, the deeper the green colour.
