I've been traveling a lot and about to start another burst.
The nice thing come home is the view. Here is one of a double rainbow.
One interesting fact of a double rainbow is the color are inverted.
While a primary rainbow is visible when light is reflected once off the back of a raindrop, a secondary and usually dimmer rainbow is spotted when light is reflected twice in a more complicated pattern.
The colors of the second rainbow are inverted, with blue on the outside and red moved to the inside. The second bow appears dimmer or cloudier because much more light is released from two reflections, and both bows cover a larger portion of the sky.
Zooming into the above picture you can see the colors are inverted.
