In the pictured photo, dark and sharply defined ring shadows appear to constrict the flow of color from Saturn's warmly hued south to the bluish northern latitudes.
Aside from the color differences, the cloud morphology is quite different in the polar regions compared to the mid-latitudes. Bright, isolated clouds dot the high latitudes, while Saturn's middle is characterized by flowing cloud bands and the occasional bright or dark vortex.
This view looks toward the lit side of the rings from about half a degree below the ring plane."
