Your Lyin' Eyes...

The picture at right (click to enlarge) appears to show a pair of blue spirals and a pair of green spirals on a red/purple background. That's what your eyes are plainly telling you.

Your eyes are lying.

Both of those spirals are exactly the same color.

I didn't believe it either, so I enlarged the picture in GIMP and examined it under extreme magnification. Those colors really are the same!

All is explained here and here.
