Voyager 2 image of the rings of Saturn. The faint colour of the rings has been enhanced in this image. The C-ring (bottom left) & the particles in the Cassini Division reflect short wavelengths better & appear dark blue. The B-ring changes colour smoothly`from the outside (blue-green) to the inside (orange), which reflects longer wave- lengths most efficiently. There is a sharp change in colour between the B-ring & the C-ring outside the black band of the Cassini Division. The ice of the particles composing the rings is probably coloured either by impurities or by damage to its crystalline structure from high-speed subatomic particles trapped in Saturn's magnetic field.
