I have seen photos of sunrise rainbows, but I had never seen one in person until this morning. The orange-pink of the sunrise alters the colours of the rainbow to fill the sky with a pink-gold-orange arch.

You can even see a hint of echoes of the rainbow.
Fleeting, but spectacular!
Addendum: Here's another photo I took, this one with my Note2:
