Saturn’s Rings
Possible variations in chemical composition from one part of Saturn’s ring system to another are visible in Voyager 2 and other pictures as subtle color variations that can be recorded with special computer-processing techniques. These highly enhanced color views were assembled from clear, orange and ultraviolet frames from a distance of 8.9 million kilometers (5.5 million miles)I.
In addition to the previously known blue color of the C-ring and the Cassini Division, the bottom picture shows additional color differences between the inner B-ring and and outer region (where the spokes form) and between these and the A-ring.
