Illusion: an instance of a wrong or misinterpreted perception of a sensory experience
The base of this poster is the Ishihara test. If you stare at the poster, you'll find some stuff, like spaceship, candle, lion,genitals and many other.
First I randomly placed some coloured triangle, then I made different colour groups, contrast pairs, like complements, light and dark, simultaneous, warm and cool. I made only the half of the poster and the illusion title in the middle, then I flipped it horizontally.
