I saw an "Eye of God" photo that had blue in the center and pink around the outside of a circle.

I thought to myself, I have seen the horizon from all angles rimmed with pink-purplish clouds and the center being all blue. And if you were looking up, it looked the same, a circle rimmed with pink with blue in the center.


Also, there is The Wizard's Rainbow.

The bend of the bows.

Here contains a segment on the pink bend...
