Novil, what is this graphic supposed to be? I just see three colored swirls.

The "green" and "blue" are the same color.

For those still doubting, this is a picture with some of the orange and pink lines taken out of it. The parts with the lines still hold the illusion, interestingly enough.

The pink/purple makes it seem blue, and the orange makes it seem bright green. This illusion alternates having the pink/purple lines go though this color, and having orange lines, making it look like each stripe has its own color. It's impossible to see this unless the orange and pink lines are taken out.
