Orb Changing Color as It Speeds?

Photo date: October 25, 2015. Photographer: Mark Mahin.

The photo below was taken while photographing ordinary drops of pure, clean water falling against a dark featureless background.  Below what looks like several orb faces, we see an orb that seems to be speeding as it changes color from orange to white.  Quite the little trick!

This is another example of the orb centrifuge effect, in which orbs are spinning around the outer edges of a water drop. See this series of photos for 77 other examples of this strange effect.
