Rainbow Saturn
South to north: pastel salmon to yellow to blue. Saturn appears calmer than Jupiter because of cooler temperatures at cloud tops. The blue clouds in the northern hemisphere are thought to be a winter phenomenon. Saturn's axial tilt is a little more than earth's, but the 29.5 year rotational period means an earth-equivalent winter longer than seven years. Still not up to the white witch's standards, but long enough.
