Stare at the picture. I mean really stare at it. Interesting how the mind puts color where there is none. If only for milliseconds.

Good old retina burn in. What's really cool when I look at that is that I can still see the partial eclipse from a couple of months ago too.

Allan has it. Shift happens at the retinal level. Red receptors get fatigued so green receptors aren't inhibited as much.
For the analytical, part Young Helmholtz part Hering theories of color perception.

With a little white tab, let it melt in your mouth you can see colors everywhere.

I think it's magic.

Of course, it could be what njlarry said and still be magic.
