Seeing Blue?

Check out this color illusion I found on the Bad Astronomy Blog...
The stripes in the BLUE spiral are the same color as the stripes in the GREEN spiral!! Look in close and you'll see Green stripes next to Magenta stripes and our brain compares them to make it look more Blue. The stripes are actually mostly green with a splash of blue!! Just another reason why we can't always trust our senses. "We make up our own reality as we go along", a comment made on the Bad Astronomy blog.
