The blue and green lines are actually both the same color.

I’m not lying. Explanation under the cut…

“The reason they look different colors is because our brain judges the color of an object by comparing it to surrounding colors. In this case, the stripes are not continuous as they appear at first glance. The orange stripes don’t go through the “blue” spiral, and the magenta ones don’t go through the “green” one.”

Still don’t believe me? Test it out in photoshop.
