Why does the red and orange lights appear to be "blinking" and the blue and green lights appear to be still? The lights on this hula hoop are always stagnant, and in every picture this exact same thing happens.

  • $\begingroup$ I don't see any blinking effect in your image, but what you're experiencing might be related to the flickering wheel illusion of Sokoliuk and VanRullen. $\endgroup$ – PM 2Ring Jun 5 at 4:38
