Quizplus · Accepted Answer

The distinct colors in narrow features suggest that different materials may have been added to the ring system at various times, which contradicts the idea that all of Saturn's rings were formed at the same time. The trace amounts of chemicals other than water ice in the ring particles may be responsible for the different colors observed. Furthermore, the fact that ring particles have distinct colors in different regions suggests that the particles may have migrated substantially from one ringlet to another.
