This illustration appears to show green and blue spirals, but in fact the apparent green and blue are exactly the same colour. More about this here and here.
What? I see only alternating thick purple and teal (blue-green) spirals, and some thin orange ones going the opposite way. I don't see any effects that are distinctly blue or green, and none of the three types of spirals look any different from others of their type in hue or shade. I'm not seeing what the illusion is here.
Then again, that classic black/white pattern which supposedly has illusionary gray spots in them? Can't see those either.
Waiiit... I went back to look at it again and just noticed that the orange lines aren't really spirals, and end in purple lines which cross over half of the teal ones... so now I have some inkling of what probably causes the illusion, but I'm still not seeing it.
