Colorful Orbs, One a Baffling "Sun Next to the Wreath"

Photo date: December 17, 2015. Photographer: Mark Mahin.

The photo below was taken in Grand Central Terminal in New York.  We see a bright blue orb at the top, and next to the Christmas wreath is a rare yellow orb. I have photographed hundreds of blue orbs at this location, but it is very rare for me to get a yellow orb at this location (although I get lots of non-lunar yellow orbs in the night sky, as shown here).

Below is a closeup of the yellow orb. This is not lens flare, as the little light behind the orb was way too dim and distant from my camera (at the opposite end of the huge station) for lens flare to be created.
